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.
