Species/Kinds (for Peg...and others)

Cheetahs can crossbreed with neither lions nor domestic cats, however, so there must be more than one kind of wild cat, under this definition.

Mitochandrial Eve is not the most recent, common female ancestor. Y-chromosone Adam's mother, by necessity, must be a more recent common female ancestor. Eve is the most recent common matrilineal ancestor, meaning that she is everyone's mother's mother's mother's mother's mother's.... etc. There are plenty more female common ancestors who lived far more recently, but to get from each of these to every person living today, it would be necessary to trace at least one line through at least one man.Edited by caffeine, : Just noticed the quote tags were a mess

There is a big problem with defining kinds this way, just by using their common names. Based on the common names of animals I was brought up with, there would be a rabbit kind and a hare kind. I had great difficulty explaining what a hare was to my Czech colleague however, as they don't have separate words for rabbit and hare. Is there a hare kind and a rabbit kind in Britain, but only a rabbit kind in Czech Republic?
