maybe your penis only dont become large.. lol!!!

why penis didn't become larger

Choken described a good example of camofloge. The cameleon does this also and other species. Being able to blend in and change color has nothing to do with evolution, though. (please excuse my spelling)

This progress is completely different from chameleon's ability. Chameleon has the ability to instantly contract/expand it's color pigments and thus change color. The example with the butterfly is explained in a previous posts but it took generations. A different example would be if an animal would migrate to a colder. Over time, it's descendants (children's children) would develop thicker fur to resist the cold better, whiter coat to hide better in snow and other similar things.

I thought the chameleon would develop this ability after millions of years of evolution, and not instantly? You give facts about creatures, but nothing proves that something evolves or has evolved.

I didn't mean that chameleon got his ability instantly. I meant that you can't compare his ability to change his color to the example that I mentioned. If you look at different regions of the planet; Arctic, Tundra, temperate, Tropical or Deserts you should see that the animals living in those areas are specially fit to live there and wouldn't thrive that well in most other biomes. Earth is always changing. The animals change with it. I don't see why it's so hard to believe that.

Look. Carrying on a conversation on this scale is too hard here with the limited space we get and we'll just end up flooding the comments with our posts. I think we'll just have to agree on disagreeing.

I agree. And I am glad you are wise enough Choken1, to realize this. My responses would be an entire book, really an entire book. And likewise, your comments would be lengthy. Besides, this is supposed to be a dinosaurs here, and it wouldn't be fair.

Camouflage is actually a strong point when it comes to supporting evolution. It's not like this happens "just because". It's survival of the fittest. Whenever a mutation occurs, and it happens all the time, the resulting offspring would either have characteristics that are better or poorer then the parent. This could be different colored fur, differently shaped scales, stronger hind legs, poorer vision and so on. If these changes help the creature to survive it will live to make offspring.

There are thousands of different breeds of butterflies that are vastly different. There's also a huge difference between black bears and polar bears. Neither one could live each others territory. It's just like tigers and lions. They started out the same once but different environment changed them. Evolution is a long term effect of natural selection. Undesirable traits disappear while the desirable ones are enhanced, changing the animal. It takes generation for noticeable changes to occur.
