Since we're sharing ideas and not arguing over the correctness of something that matters more in a classroom setting than it does on a forum for hobbiests, I'll play along and suggest that the evolution of species can occur by many different mechanisms... one being when different species hybridize, intergrade, or even when morphs adapt to a different niche within or beyond the range of its parents (phylopatry or allopatry). In these cases, even morphs that begin to assortatively mate would represent a transitional form until they establish reproductive isolation. If one looks at organisms on a geologic or evolutionary time scale, one might even say that all organisms are transitional forms . With intense inbreeding (bottleneck effect) and a little luck (genetic drift), over a long period of time, I'm certain that reproductive isolation (and hence speciation) could (and has) occur(red). Review this thread, then scroll through the posts before it for a real world example where this has occurred (http://www.thamnophis.com/forum/gene....html#post7657). The point is that these morphs represented transitional forms until they essentially (dare I say the word?) s.p.e.c.i.a.t... I can't finish it

The problem with debates over biological terminology are that even words like "adapt" can mean slightly different things to specialists of different disciplines (i.e. physiologists, evolutionary biologists, ecologists, etc.). Yet they have specific definitions within their disciplines. Cheers,
