if i recall that gene is in all cats that have all white fur and blue eyes, very cute cats but sadly are deaf. its still arguably evolution its just if it werent for us humans breeding them. natural selection would have killed them offYopaz said:So there's a gene in cats that make cats white and in many cases the same gene makes them deaf. They do not survive in the wild because they lack one of their most important characters. They do not reproudece and create offspring that is deaf which goes towards creating a new species because being deaf is bad. This is a random mutation that's negative. Do you honestly think it will survive and create a deaf population?
Read my entire post and you will see that I said evolution is a product of random mutations, but random muttions are not evolution. Evolution affects more than one individual. More than one line. Evolution is the process of adapting to the environment. Do you think that it is by chance that the polar bear is white or do you think that those with different colours weren't fit to live there? Evolution is both the process of mutations and the process of picking out what is beneficial. The ones that don't adapt will have a lower fitness and their genes will dwindle in the gene pool.
in terms of your polar bear example, it is partly by chance that bears in the region had pale fur (after a few centuries of breeding would get white fur, same thing with white lions) the bears with white fur could hunt in the snow, while those with darker would starve due to competition and stayed in forest ares.
evolution is the mutation, natural selection is getting rid of the weaker species
for the most part i think we agree with eachother but we worded it and a bad way which is why we are arguing
but the thing i do disagree with you on was that you said evolution does come out of need. you tried to argue it but i didnt get your explanation of it
but i do disagree with the idea it comes out of need
