About the lizards, that is not evolution. The cecal valves came by reproducing with a lizard in the area that did have that coded in the DNA and was viably reproductive with the new lizard. The fact that their jaws changed because their diet change is not evolution, their diet changed so their jaws changed. The same exact thing can happen to birds--not to their offspring but to the bird itself. If a bird is used to eating soft foods, its beak will tend to be short and thin, but during a drought, soft foods tend to die first, therefore, if the bird likes to live, it must find something else to eat. Suppose it finds nuts, but the nuts are too hard for the beak to easily break and eat. What would happen to the beak? Same thing that would happen to your arms if you lifted weights. I once saw a picture of Orrin when he was in his teens-ish. He had much less muscle than he does now. That does not mean he evolved, just that his specific body adapted to a new environment. As far as "having a larger average size, shorter hind limbs, lower maximal sprint speed and altered response to simulated predatory attacks compared to the original Pod Kopište population", that is because they are no longer being chased by predators. If I were a runner, which I haven't done in a while, and had children that were not runners, my kids legs would grow differently than mine did. That is not evolution, but mere growing patters (see Orrins muscle argument but think of his sons who don't currently lift weights--their pectoral muscles are thinner and weaker). Again, not evolution, just different lifestyle. Technically, they are still the same exact species (can interbreed) with the other lizards. Yes they changed to suit their environment, but that isn't the same as evolution. Orrin changed to suit his environment, does that mean he is no longer human? Orrins children are not as fast or as strong as he is. Does that mean they are no longer human? For both, of course not. Every living organism is programmed to deal with life and can grow to adapt to different environments, within a certain limit. That is not evolution, just adapting to new environments. But thanks for keeping me on my toes and making me think!
