Variation Many examples of variation within a kind, but no examples of transformation to another kind. (Bacterial resistance, Peppered Moth, Whistler Bird, pure bred dogs, cattle, horses, sugar beets, roses, all sorts of plants. However, dogs start with dogs and end up with dogs and moths started with moths and ended with moths.) Adaptation There is constant reference in evolution to adaptation, with the implication that special characteristics were developed as a resultant of a need to adapt and develop that special characteristic. Yet there is no suggestion of a mechanism whereby this change might be mediated. If the need is sufficient to cause the change, then how does the organism survive until the change takes place? I hope it's clear by now that a dog does not change into a cat or a moth. Each baby looks much like , but not exactly like it's parent. a need to adapt There is no "need" to adapt. Individual animals are different. The ones that are different in a way that lets them have babies, and pass of their particular sucessfull difference, will form the next generation. then how does the organism survive until the change takes place I'll toss in another "just so" story as an example. Let's say that a new animal, a lion, is introduced to Austrailia. Let's say the lion can easily catch the kangaroos and prospers. Now the lions keep having babies, the slower kangaroos keep getting eaten and don't have babies, and the result is a lot of lions and few kangaroos. The lions starve and a few kangaroos are hiding behind rocks. These are the fastest, or trickiest jumping ones, (and some that were lucky). The next generation of kangaroos will be much faster and/or trickier than the previous. Either some of them survive and become somehow different, or they go extinct (and the lions starve again). TP
