Adam and Eve, not Ug and Eev!

Question from Dontay:
Evidence of dinosaurs has been found…museums show that cavemen existed…. But… How can cavemen be real if Adam and Eve are supposedly the first people on earth?

Answer by SmartLX:
If by “cavemen” you simply mean people who lived in caves and hunted and gathered for a living, then perhaps Adam and Eve’s immediate descendants did that once the garden of Eden was closed to them. The timing doesn’t work out at all when you count the supposed 34 generations from the Biblical Adam to the Biblical and historical King David and compare them to the scientifically estimated dates of the cavemen’s remains, but people who are motivated to prop up the story of Genesis will accept it anyway.

If on the other hand you mean Neanderthals and other departed species within the genus Homo, there you have a conflict which is less easily dismissed. The story goes that God not only made Man more or less in his present form (or a super-version that was huge and could live for centuries) but He made Man in his own image, which is poorly defined but usually taken to mean an image of perfection. “Lesser” or more primitive versions of Man don’t jibe with this idea at all. That’s why creationist explanations of the evidence simply assert that they were all just modern-type humans with primitive lifestyles.

As for dinosaurs, all evidence points to the fact that the last ones were dead millions of years before the first humans were born. Not so for most creationists; rather than deny they existed, many of them say dinosaurs were present on the Ark, and they’re depicted as such at the new Ark Encounter park in Kentucky. Any evidence or argument that so much as requires the expression “millions of years” is explicitly demonised.

Why Fight the Young Earth?

Question from Jerry:
I very often hear about if the Earth is ~6000 – ~10.000 years old or if it is billions years old.

But I don’t understand how this is an argument, just because in the Bible it says God created the heavens and the earth and all live on the Earth in 6 days.
So.. if Adam would do scientific research on the universe and the planet, would the planet look like its only a couple of days old?
I can’t imagine how that would look like, because scientifically, a 6 day year old planet would look nothing like a planet, more a ball of lava.

So If God created the Earth to be habitable, it would HAVE to be a billion year old planet, there is no other choice. So of course the planet looks old, even if it’s created just a second ago.

So many atheists use the evidence for an old Earth as an argument against Creation. I don’t see how it has any argumentative value though.
I’m wondering what an atheist’s response to this is.

Thank you ever so much 🙂

Answer by SmartLX:
Young Earth creationists (YECs) do say that God created the Earth more or less the way it is, without working through the lava-world phase over millions of years. As you say, there’s strong evidence for an old Earth (geological, astronomical, radiometric, etc.), so a young Earth would have been created with all that evidence essentially falsified. This is the problem though, because why would God go to so much trouble to deceive us into thinking it was so old? Especially if we’re supposed to take the roughly six thousand year history of the world in the Bible seriously?

Of course the problem with any anti-religious argument that goes, “Why/how would God do this?” is that it’s possible to assert as gospel (sometimes literally) any answer which explains it away. The Earth looks old because God’s testing our faith, for example. Thus faith is insulated from any attempts to make their beliefs sound silly, and plot holes in scripture can be ironed out.

The main point of this particular battleground is that young Earth creationism follows on from Biblical literalism. The Bible says the world was created in six days, and that there have only been a small number of generations of humans since then, so that’s the way it was. There’s no good reason to believe it except if you want or need the Book of Genesis to be literal. Outspoken YECs try to convince nonbelievers that the world is young so that they will accept that God created it, because supposedly nothing else could explain a young Earth. Even if they fail, they often succeed in reassuring other Biblical literalists.

To give their position a respectable veneer, in order to appeal to nonbelievers and impress believers, YECs need to make it look like it has secular scientific support, which means presenting scientific arguments that the Earth is young. The proper use of the real evidence that the Earth is old, rather than to jump straight to advocating atheism, is to simply counter these arguments by YECs, and the evidence does so very easily. Thus there is no intact evidence for a young Earth, YECs are reduced to claiming God made the world look old, the young Earth becomes a mere assertion and it cannot serve as a solid premise for arguments for the existence of the God of Abraham. Thus you can believe in a young Earth if you want but it won’t get you anywhere with those who don’t already agree with you.

How The Snake Got Its Venom

Question from Robert:
What would be your reasoning as to how the evolution of venomous snakes could have happened? Obviously, the first snakes did not start off with venom glands in their heads. That means that they were getting along just fine without any venom to kill their prey for hundreds of thousands or millions of years. So why in the world would venom glands evolve inside their heads? That is not ‘natural selection’. Indeed, that is completely unnatural. A creature wants to keep poison out of its body! So why would any creature start to make poison inside its body? That makes no sense at all. And it would potentially be extremely dangerous to that creature.

But just for the sake of argument, let’s say that such a totally bizarre thing occurred. So now what? You have snakes with venom glands in their heads. How in the heck are the snakes supposed to get the venom into their prey? That would be 100% impossible for snakes to do that without hollowed out, syringe-like, very sharp fangs.

That’s a HUGE problem. That means that snakes which somehow evolved venom glands, would then have to evolve syringe like teeth. And there is absolutely no way that could happen because that would require forethought and planning. And it would totally go against the theory of natural selection. Also, by the time that snakes could have strangely evolved syringe like teeth, their venom glands would have already been naturally phased out because those glands would have been totally useless for an extremely long time. But again, just for the sake of argument, let’s say that this second totally bizarre thing occurred. Now snakes would have had to evolve a structure that would connect the venom gland to the syringe like teeth. How could all of these bizarre things happen accidentally? …. or naturally?

Answer by SmartLX:
We don’t have to rely on my reasoning, not when Scientific American has a full article on this exact subject and Wikipedia has a good summary sitting right there. What the heck, here’s the National Geographic article too. These are literally the first three results when you Google “evolution of snake venom” so I guess you didn’t start there.

The first snakes actually did start off with venom glands because the glands first evolved in the ancestors of snakes, four-legged burrowing lizards more similar to the Komodo dragon. The proteins in venom share DNA with compounds that do other jobs. One is saliva, which breaks down organic material for digestion. Immune system proteins, which attack foreign elements in the body, are another. One compound that isn’t mentioned is stomach acid, but this is another dangerous substance that is essential to normal bodily function. We need poisons in our bodies to survive, only they’re poisons we’re able to tolerate because of how they’re produced and contained. Venom evolved many times over throughout the animal and plant kingdoms, because it has lots to build off.

As for delivery systems, of which there are many, you don’t need much of a starting point. Toads secrete poison on their skin and let it sit there, because the only animals they want to poison are those who try to eat them, so any number of bodily glands could have switched their purpose. Spitting cobras squirt venom forward, so what if they started by just plain spitting, or to be more specific, gleeking? With this technique, even humans can shoot liquid a long way from the body straight from a gland. A gland with a naturally effective nozzle like this can slowly evolve into either a weapon that can be aimed or a hard retractable tube that can inject, because every little bit closer it mutates to either one of these makes for more effective hunting and defense, and ultimately a better chance of survival.

With the specifics covered, let’s look at the overall nature of your challenge because it is VERY similar to those that have come before. You point to something remarkable and ask how it could have happened, and implicitly assert your own explanation by elimination after assuming no good answer is forthcoming. A textbook argument from ignorance (a harsh name, sorry, but the official one) and thus an informal fallacy, which is a failure of the premise of an argument to support its conclusion. It fails for several reasons: obviously it’s rebutted if an alternative answer is presented, but even if not it relies on the assumption that if you and I can’t think of a way then it’s impossible. We’d have to be gods ourselves for this to be true. I point out this fallacy whenever it comes in because it is the basis of many of the arguments for God, and every creationist argument. As a result, these arguments are only good for reassuring yourself and those who agree with you, because by themselves they have little power to persuade.


Question from Moses:
I’m not going to enlighten you on my personal beliefs, because it is moot to my question that I will pose momentarily.

I have made note that your readers all seem to agree that science and rational thinking should be revered above all else.

And further understanding that choice is a free will, individual thought process or belief that may or may not be brought into actions.

So here is my rational, scientifically proven, free willed, intellectual question: “If there is no creation theory, then why isn’t the earth filled with abundant quantities of deuterium just as the rest of the solar system is?”

p.s. The world’s space agencies has sent, and continues to spend billions of dollars for, probes and robots searching for life, but science has proven that the water here on earth is certainly different than elsewhere in our solar system.

I await your response in earnest.

Answer by SmartLX:
Thanks in advance Moses, it’s almost never this simple.

Deuterium IS abundant on Earth; one in about 6,400 hydrogen atoms in ocean water is a deuterium isotope (which is just a hydrogen atom with a neutron) instead of the usual type. This ratio is higher than some of the objects in space we’ve been able to analyse, and lower than others. All measurements within the solar system including on Earth have been within 1-2 orders of magnitude (specifically a factor of ~30), with Halley’s Comet and Comet Hale Bopp near the high end and Jupiter’s atmosphere near the low end. The fact that our ratio is closer to the comets has caused some to theorise that comet collisions with the early Earth are the source of much of our water. There’s nothing special or unique about the ratio at all.

Your personal beliefs may be moot, but to an extent they are also obvious. Only a creationist would make an argument from ignorance based on the supposedly unknown reasons for a scientific factoid (and I’m not surprised that the factoid itself is bogus, though perhaps you are surprised), or use the term “creation theory”. Only devout theists are creationists because faith in a creator is ultimately the only compelling reason to be one. You might be a Christian creationist or a Muslim creationist; few other religions have so many.

As for the water, we’ve known about the ice crust on Europa since the 1970s and it’s likely that Mars and Venus had liquid water in the past. Multiple extrasolar planets are the right distance from their stars to have liquid water, provided water exists there; here’s a list.

Counting Chromosomes

Question from Ken:
I’m agnostic. There’s one thing I’ve always wanted to understand about evolution for a while, and I hope this is the place to get it answered.

When I learnt about it, in school and university, they expressed the idea of increment changes (whether modifications of traits that were already there, or new traits through mutation) over time, passed on through generations, “chosen” by the ability to procreate and pass on genes. That, I think I get for the most part.

But what I never really understood is how the number of chromosomes could change over time. How can chromosome numbers increase and decrease? I mean… let’s say an individual somehow has it happen, shouldn’t he or she be unable to produce viable (or fertile?) offspring with others of the species because of the wrong numbers of chromosomes? How does chromosome number change at all? The only way I know is through issues that happen in meiosis, the kind of stuff that causes Down’s Syndrome, and the XXY and X gender chromosomal abnormalities that cause problems in humans.

So, my question is: How can chromosome number change in to produce a viable, fertile individual for it to be able to spread to an entire species?

Answer by SmartLX:
It’s a good question because a sudden whole extra chromosome full of junk, or a whole one gone missing, can indeed cause serious defects. That said, it helps to remember that a chromosome is merely a container of genes, and the number of chromosomes has very little to do with the amount of genetic information in each.

The addition of a chromosome is the more complex process, so I’m linking to an explanation of one mechanism by PZ Myers. Essentially, one chromosome’s worth of genes ends up being shared by two, and at first it can interact just fine with the old combined chromosome because the total sequence is the same. This does introduce a higher rate of error until individuals with the split chromosome start mating with each other, at which point there’s no longer a downside. Once the new number of chromosomes is settled, each chromosome is free to mutate independently and add new genetic information in the usual ways.

As for a reduction in chromosomes, we need look no further than our own genome. Our #2 chromosome pair is equivalent to two separate chromosome pairs in our closest ape relatives, but fused together. You can tell because there are two end markers (telomeres) right in the middle of it. No genetic information was lost, it was merely repackaged. This, importantly, is a very clear example of the kind of predictions one is able to make using evolutionary theory: the number of chromosomes in our genome compared to our ancestors’ (i.e. one less) tells us that exactly one fusion must have occurred, and we can then check the genome for only one extra set of markers.

And The Rest: You Finally Made A Monkey Out Of Me

If we evolved from monkeys, why are there still monkeys?

Answer by SmartLX:
Welcome to And The Rest, a potential new series where visitors and I try our best to create serious, concise, easy-to-understand answers to the most ignorant, misguided rhetorical questions and other hopeless arguments posed by theists who think they’ve got the ultimate trump card.

When you get one of these it betrays such lack of understanding and willingness to parrot propaganda that you may get angry and refuse to answer it; most of the time this will simply send the message that it works as rhetoric. I’d rather work on a library of straightforward answers which can be passed on and spread as wide as the questions themselves, until it’s inconceivable in each case that the question was ever given merit by anyone.

Right then, the monkey question is the classic example, so here’s my attempt to clear it up as quickly and simply as possible:

“Because not all the monkeys evolved into humans. Most of them evolved into other kinds of monkeys. They had different offspring like any family does. [Bonus semantics if you’re snarky:] And technically it was apes, not monkeys.”

Think you can come up with something more elegant? You’re probably right, so have a go in the comments. Otherwise, comment with some other faux “stumpers” we should cover in this series. Cheers.

The Dating Game

Question from Bryan:
Why is radiometric dating considered accurate? I will give two examples, one speculative and one based on actual observations:

I understand half-life, log base-2 calculations and radiometric decay. What I don’t understand is how we assume a starting point for radionuclides v/s daughter nuclides. For example, what if the meteorite that hit the earth and killed the dinosaurs (or any other large meteorite) was a big ball of lead? We have not found traces of it, therefore, we can only speculate what it could have contained. If it were a big ball of lead and mixed with the elements on earth, it would give the appearance that more U-238 half lives had occurred and give falsely high age outputs. (Granted, this is probability based, so is the statement that the meteorite wasn’t lead). This is just one possibility of something that could throw off parent-daughter nuclide ratio. It could have easily just been that there was more lead on earth than we previously thought at the beginning.

This one is not speculation. C-14 dating depends on two things:
1. That production rate and loss rate have been in equilibrium for an extended amount of time, and
2. The equilibrium ratio has not changed in an extended amount of time.

C-14 is produced in the upper atmosphere when various forms of cosmic radiation produce thermal neutrons. A N-14 atom nucleus collides and absorbs the neutron and ejects a proton, thus, making C-14. This process is attenuated by the existence of the earth’s magnetic field. The stronger the magnetic field, the lower the production rate of C-14, therefore, the ratio of C-14:C12 would be initially more weighted to C-12, and therefore, give a falsely older output. The earth’s magnetic field has decreased 10% since Mathematician Gauss started observing it. This decrease is exponential. In the year 7800 BC (rounded) the magnetic field would have been approximately 128 times stronger than it is now, based on current observations of the decay rate of the magnetic field. This would have caused 100% decrease in C-14 production. (Which also begs the question, how C-14 is in fossils that are millions of years old? – throw in the half life of C-14 being only 5700 years (rounded) with that question too). In fact, Dr. Libby noted that the C-14:C-12 ratio was NOT in equilibrium when designing the test, and subsequently decided to assume equilibrium anyway. So why is this test considered accurate when there is definite evidence to the contrary?

Answer by SmartLX:
Radiometric dating is not considered universally accurate. It’s a measurement like any other, there are any number of ways to get it wrong, and there are documented examples of when it has gone wrong. Despite this, it’s been successfully used to accumulate a mountain of evidence that the world is older than a literal interpretation of the Bible would lead one to believe. The threat to Biblical literalism really is the only reason anyone challenges the principle anymore, and it’s also the only reason why you would ask a question like this on Ask The Atheist instead of an actual science site. Mind you, it wasn’t all used explicitly to disprove the Bible like the scientific conspiracy some believers imagine. Scientists were investigating all sorts of questions; the answers just happened to lie between tens of thousands of years and billions of years in the past.

There are almost 20 independent methods of radiometric dating, each based on the decay of a different parent isotope into a daughter isotope. Each has its own starting point, a known past event when the substance to be dated theoretically contained known proportions of the parent and daughter (which could be all of one and none of the other). This is non-negotiable because a method is useless without a reliable starting point, as you would agree. The implication, then, is that the knowledge of serviceable pre-conditions is a major reason why each of the ~20 methods was developed in the first place, out of the multitude of unstable isotopes in the heavier half of the periodic table. It’ll always be there, if you pick a method and look it up.

If a method’s starting point is the least bit ambiguous, say, vulnerable to contamination by outside sources of the daughter isotope (like your meteorite that’s already full of lead), one or more other independent methods are used in conjunction, taking advantage of other elements in the object. The fact that unrelated methods consistently return almost precisely the same result is a major reason for confidence in the principle as a whole, since their reasons for potentially failing are so different.

As an example we’ll look at carbon dating animals in more detail.

Artwork by Randy Russell at Windows to the Universe
Artwork by Randy Russell at Windows to the Universe

As you wrote, Carbon-14 is formed when radiation strikes nitrogen in the air, which means it happens all the time above ground. It’s absorbed by plants in the carbon dioxide they breathe, and then eaten by animals. The starting point is therefore when the animal dies and stops accumulating it. Afterwards the carbon-14 decays back to nitrogen-14, which normally dissipates as gas but is trapped with the body if the specimen is buried. Dating it is then a matter of comparing the amount of N14 to the remaining C14. This works for about 50,000 years post-mortem. Afterwards the amount of remaining initial C14 is so low it cannot be distinguished from the small amount of C14 produced in a different way: alpha or gamma radiation from other radioactive materials in the earth (with millions of years more longevity) can re-irradiate atoms of the N14 and convert it to C14 a second time. This effect is the reason why C14 would have been detected in dinosaur fossils, which are WAY too old to retain their own C14. Hence, other elements with longer half-lives are used to date them instead.

On to your other point. The observation that led to your claim about the Earth’s magnetic field was merely that the dipole field has apparently decreased since 1835.
– That it is a consistent exponential decrease is only an assertion, so raising it exponentially as you go back is unsupportable. The line of best fit between only two data points cannot be assumed to be a smooth curve.
– That it has consistently decreased at ANY rate contradicts other evidence collected from the magnetisation of iron particles in ancient clay pottery (mentioned here), which indicate very clearly what the magnetic field was like earlier on. From just other two data points in history we know it was 45% stronger 3,000 years ago and 20% weaker 6,500 years ago (so in this case, the line of best fit is a wiggle).
– The initial observation only took the dipole field into account. Geologist Brent Dalrymple wrote that increases in the nondipole field, discovered from the very same measurements, resulted in no significant change in the overall strength of the field at all over this particular interval.
– As stated, most or all radiometric dating methods rely on the proportion of the daughter isotope to the parent. The magnetic field affects the generation of carbon-14 in the atmosphere, but this would have no effect on the proportion of C14 to N14 in an already-buried corpse if the N14 is all coming from the C14.
– Does the strength of the Earth’s magnetic field so directly affect the production of every radio-isotope used in every form of radiometric dating? I don’t know, but you’re the one claiming they don’t work, so have you checked?

It’s worth pointing out that carbon dating is the best-known dating method but it’s the least of a young-earth creationist’s worries, as it only goes up to 50,000 years. That’s only one order of magnitude off the desired scale, as opposed to the six orders of magnitude of the actual discrepancy between the Biblical timeline and the evident reality of geological time.

Ham vs Nye: Whoever Wins, Who Really Wins?

Question from Jordan:
Hello ATA.

I was wondering how you felt about the upcoming Ham/Nye debate. From what I can tell, most atheists are not happy about the debate. They claim that an atheist should never debate a creationist because there is nothing to debate—evolutionary thinking has already won. They claim that the act of simply debating gives the creationist credibility.

I think it is obvious that this atheistic claim sounds like an excuse. If creationism is so flawed, it should be simple for an atheist to dominate in a debate. Yet creationists keep asking, and many atheists keep refusing. It is as if the atheist is thinking, “I’d rather have people THINK I’m a coward, than for people to KNOW that I’m wrong.” The fact that Bill Nye is willing to debate, shows he is confident in what he believes.

From my experience (as a creationist) on this site, you all seem happy to debate someone on the issue. Are you excited about the upcoming debate (like myself and most other creationists)? Do you see this as a chance for the idea of creationism to be buried, or are you upset with Bill Nye like Dawkins and the many others like him?

Answer by SmartLX:
Whether evolution is or isn’t a fact (it is) is not the reason these atheists don’t want Nye to debate Ham. A debate depends very little on whether one side or the other is objectively correct. It’s the ultimate exercise in rhetoric, where even if you don’t convince a single person you can still be ahead on rhetorical “points” at the end of the debate and thus “win” it.

The mass refusal of evolutionary biologists and other scientists to debate creationists is a relatively new thing. Debates like these went on all the time in the 80s and 90s, which is how people like Duane Gish became famous for doing them. Richard Dawkins even did one at Oxford, when creationism actually had a chance at being taught there. The concerted refusal was later instituted, by Dawkins and other major figures, because of the observed effects of these earlier debates.

– If the audience consisted mostly of creationists or at least devout Christians, as will certainly be the case in the Ham/Nye debate, the debate sounded like a victory for the creationist no matter what was said.

– There are a multitude of creationist “refutations” of evolution (all in the pattern of “evolution can’t explain X, therefore God”) dozens of which can be rattled off in a matter of minutes. Even if there’s a perfectly good evolutionary explanation for each one it takes a lot longer to explain, so some points will necessarily go unanswered and that’s a terrible thing to happen in a debate. The late Duane Gish would throw out as many claims as he could right at the end of a debate, knowing most of them would stand unchallenged purely for reasons of time. To this day, it’s known as the Gish Gallop.

– Even if the creationist was soundly and undeniably defeated, he (I’d say “or she” but most or all of the prominent ones were men) would be invited by other creationists to speaking engagements and radio shows where he could make the same points again, alone and undisputed, as if the debate had never happened. According to Ray Comfort, the main goal of any evangelist is to spread the message, regardless of context; God supposedly does the rest of the work, or doesn’t. When he talks about his televised debate with the Rational Response Squad, the important thing wasn’t that he adequately defended the Gospel but rather that he reached the audience of Nightline. (Also see his book, You Can Lead An Atheist To Evidence But You Can’t Make Him Think.) Any embarrassments during a debate can be buried under a subsequent succession of appearances with sympathetic hosts and audiences, where the combative “evolutionist” can be demonised.

Besides the above, the claim that creationists gain credibility from debating scientists is a valid one. Credibility among the already devout for not being swayed or cowed by the scientific establishment, and credibility among the neutral for appearing with a qualified professional as an apparent equal, even if he gets trounced. The credibility, however, is secondary to the publicity; Ken Ham may have been mentioned more in mainstream media in the last few weeks than in the previous several years, and far more positively because the news isn’t about the imminent financial failure of his Ark Park project. Speaking of which, the proceeds from DVD sales of this debate will go straight into the coffers of Answers in Genesis and prop up the Park, which all by itself is a reason for non-creationists not to support the event.

To summarise, there are plenty of reasons why Nye should not debate Ham even if it’s assumed that Nye will win. Furthermore, there are plenty of ways for Nye to effectively lose even if he is right and Ham is wrong. On a pragmatic note, the simple fact that creationists everywhere are so eager for this debate to happen (and that Ham set it up in the first place) means that they expect their cause to benefit from it one way or another regardless of the arbitrated outcome (if there’s even a judge), and I don’t think they’re wrong. Nye shows no signs of pulling out, so I guess we’ll see what happens.

Well, Nye is generally accepted to have won the debate by a mile, but AiG received such a boost in financial support and apparent legitimacy that it is at least claiming that it’s secured the municipal bonds necessary to break ground on the Ark Encounter park. No surprises at all.

A Little More Than Kin, And Less Than “Kind”

Question from Anisa:
Is there any observable evidence of Darwinian evolution where there is a CHANGE OF KIND? By ‘KIND’, I mean from monkey to human etc. Not adaptation. CHANGE OF KIND.

Answer by SmartLX:
“Kind” in this context is used only by creationists as a pseudo-scientific term adapted from its use in the Book of Genesis, and a very inconsistently defined term at that. It has no place in actual biology, and nor does the Hebrew version “baramin”.

Regardless, there is plentiful evidence of the common descent of all living things, which means that no matter how you group them as separate “kinds” they are all descended from the same organisms, and their “kind” is irrelevant. Wikipedia has a comprehensive list here, ranging from geographical to genetic to morphological evidence, so I won’t cover it all redundantly.

You did ask the right question; “kind” seldom groups animals below the level of genus (except in the case of humans which are separated even from other apes in the genus Homo), so changes of that magnitude take far too long to be observed in a lifetime or even over all of recorded history. It is the evidence that is observed, not the full-scale phenomenon itself. That said, there have been many instances of observed speciation, where one species becomes two. You would dismiss such events as “adaptation”, as for instance a mouse becomes another kind of mouse, but there is no observed barrier to this process repeating and accumulating changes over sufficient time until the differences between relatives are greater than any “kind” could encompass. That a “kind” is a self-contained and somehow limited family is nothing more than an ill-informed assertion.

I, Ape

Question from Philip:
Is it right to call those who believe they are evolved from apes as Monkey/ape Richard Dawkins or Monkey/ape Christopher Hitchens?

Answer by SmartLX:
Calling them apes is technically correct, as not only are we evolved from apes but we are apes (not monkeys, though – they’re only related to us). I don’t know about “right”; you don’t normally refer to people as Human Joe Smith, or Human Carly Jensen. There’s no reason to add the species to people’s names unless we’re all different species.

Of course, we’re all the same type of creature, whatever it is. If you call those who accept evolutionary theory apes you’re calling yourself one as well. If you believe that you’re of a special race deliberately created in its present form by God then so are they, no matter what they think. So if you think calling “evolutionists” apes is deservedly derogatory, don’t bother because it reflects directly on you.

If on the other hand you think that “evolutionists” really are a different species, and something less than human, you need to back that up with some evidence.
