Re: Paradoxically temporal
George, et al:
This definition for speciation fits best, considering all the problems
with other definitions: E.g. Ability to mate - Tigers and Lions are
separate and distinct species, yet they can mate, and their offspring
(Ligers, and Tigons) occasionally can sucessfully mate as well. (By
sucessful I mean resultant offspring).
We cannot rely upon external decorations except in considering existing
species - and even these can mate successfully (see above).
