Dear Lithodid-Man,
I use kind with both fossil and recent organisms. I just attract a short attention in that only fossil species are defined with uncertainty (impossible to test the interbreeding). This is inconsistent for genus because of the following explanation.
Kind (genus) is the taxonomic division immediately above species. I mean that you have a kind (genus) when you are able to demonstrate an evolutionary trajectory through time scale underling and supported by fossil records. I insist on the fact that the time between two fossil records must be at least superior of 2,5 million years for a fish.
In fossil fish taxonomy, we have a few Goody-two-shoes completely ignorant of this concept. They still create genus each time they found something different. Before rejoining this forum, I was not aware about the Creatos though (nothing here like that). I suspect the concerned Goody2S to be cryptic Creationists.
