Welcome to EvC, helenavm.
If there is anyone who can direct me to a post or a website or a book that can explain how animal camouflage is actually explained by random natural selection....
Your wish is my command.
The basic idea is that animals naturally vary in their characterists, and random mutations occur that cause the animals (or plants) to look a little bit different from their parents. This can be observed, by the way.
Well, an animal that is ever so slightly harder to be seen by a predator (or prey) will be ever so slightly able to avoid getting eaten (or catching food) than one that is ever so slightly easier to be seen, and so will, on average, produce just a few more offspring, so that the next generation will contain more individuals than before that are harder to see. This repeats until the camouflage is excellent.
Speaking personally, I find few things more awesome than contemplating this vast and majestic process of evolution, the ebb and flow of successive biotas through geological time. Creationists and others who cannot for ideological or religious reasons accept the fact of evolution miss out a great deal, and are left with a claustrophobic little universe in which nothing happens and nothing changes.
