| Quote (Assassinator @ Jan. 21 2008,16:21) | You don't completly grasp the idea of natural selection Daniel. But it's pretty easy (that's why I wonder why you've got so much trouble with it...). First of all, it's relative, because natural selection matters between other groups of animals. Imagine a population of butterflies living in a dark forest, you've got red one's and you've got brown one's. The red one's will be a much easier prey for birds for example, because they're much easier spotted by a fast flying bird then brown one's. The red one's will be the number one on the bird's menu, and will get eaten much more then the brown butterflies. The brown one's can preduce much more offspring then the red one's, and after a while a dominatly brown population of butterflies will populate the forest. You can turn it around ofcourse, and set them in a brightly collored field of flowers, where the red butterflies will have a survival advantage. Thus you can get a red population in the field, and a brown population in the forest. If certain separations occure, you ultimatly end up with 2 different species of butterflies.
If anyone can correct me on errors, I'm not perfect afterall, please do. |
I don't see the difference between what you said and what I said.
The red butterflies die as a result of predators and are thus selected against.
The brown ones don't die, (because of predators anyway), and are thus selected for.
The population slowly moves from 50/50 red/brown to more brown that red.
You guys are making this out like it's terribly complicated when it seems pretty simple to me.
