Evolution is [i]not[/i] an opinion. It is a scientific theory. There are huge amounts of evidence behind it to support its claim. Artificial selection - there are tons of different types of dogs bred to specialize in different jobs. Natural selection - a process that occurs over a great deal of years and years. If a mutation of the formation of a beak occurs that significantly increases how easy it is to get food in that environment - that bird will have offspring that share that beak, then those offspring will have offspring sharing that same beak, and sometime down that line a new species will have arose. Embryonic development - shows the great similarities in deoxyribonucleic acid between completely different animals. http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/R/Romanes.jpg Can you determine which is which in the first stage? Similar bone structures - https://anthropologynet.files.wordpress.com/2008/01/forelimb-comparison-of-human-cat-whale-bat.jpg and I posted a comparison of a human vs chimpanzee with their skeletal systems. Here there are no differences between the forelimbs, only different proportions. I respect your disbelief in evolution, but don't dismiss it ignorantly without providing an argument to why a disbelief is logical.
