'Kind' cannot be a 'scientific' term by definition because it is not based in philosophical naturalism. Truth by definition is not any rational support for evolution.
"Can you please describe what you mean by "kind" -- starting with its use in the original language of the Bible and tracing its etymology to the current colloquial use of the word and any potential rigorous scientific application?"
A 'kind' is a group of interbreeding species, of which there are multitudes of examples.
So if I provide proof of a species which has evolved to where it cannot breed with others of the original species, you would agree a new "kind" has evolved?
I have no idea what that even means.
I would add that the Biblical kinds mean that plants and animals cannot interbreed (nor can they ever interbreed) beyond certain intelligently designed limits. If you wish to find out what those limits are, that is a job for science, and is currently being carried out by Creation Scientists in the field of Baraminology.
