In biology, evolution is the change in the inherited traits of a population of organisms through successive generations. When a population splits into smaller groups, these groups evolve independently and develop into new species.

Anatomical similarities, geographical distribution of similar species and the fossil record indicate that all organisms are descended from a common ancestor through a long series of these divergence events, stretching back in a tree of life that has grown over the 3,500 million years of life on Earth.

Evolution is the product of two opposing forces: processes that constantly introduce variation in traits, and processes that make particular variants become more common or rare. A trait is a particular characteristic such as eye color, height, or a behavior that is expressed when an organism's genes interact with its environment.

Genes vary within populations, so organisms show heritable differences (variation) in their traits. The main cause of variation is mutation, which changes the sequence of a gene. Altered genes are then inherited by offspring. There can sometimes also be transfer of genes between species.

Two main processes cause variants to become more common or rare in a population. One is natural selection, which causes traits that aid survival and reproduction to become more common, and traits that hinder survival and reproduction to become more rare.

Natural selection occurs because only a few individuals in each generation will survive, since resources are limited and organisms produce many more offspring than their environment can support.

Over many generations mutations produce successive, small, random changes in traits, which are then filtered by natural selection and the beneficial changes retained. This adjusts traits so they become suited to an organism's environment: these adjustments are called adaptations.

Not every trait, however, is an adaptation. Another cause of evolution is genetic drift, an independent process that produces entirely random changes in how common traits are in a population. Genetic drift comes from the role that chance plays in whether a trait will be passed on to the next generation.

@raponte1955 You implied it.

[raponte1955]

@Helge129 Did I say "scientific peers"? Please read carefully before replying.

[Helge129]

@ironman197268 A whole new protein that didn't exist before isn's a subtle change. Increased lung volume is relatively subtle, and not passed on to its offspring. Nylonase is.

A game artist is someone who creates the art assets for video games.

[ironman197268]

@Helge129 What's a game artist? Nylonase is just a very subtle change in a species. It's no different than Mt Everest climbers adjusting to lower oxygen levels from climbing to it's top so many times.

[Helge129]

@raponte1955 My scientific peers? I'm a 20 years old game artist, not a scientist lol. What I told you took only some very basic understanding of evolution and a tiny bit of research.

For everything to evolved the way it is now, yes, that does take billions of years indeed. However! Even IF skydaddy did create heaven and earth in 6 days 10000 years ago, evolution would still go on. Nylonase is real by, not to be confused with Mayonaise, which is not a protein, or an instrument.

[raponte1955]

@Helge129 You will be excomulgated by your peers! You need the billions of years!

[ironman197268]

@ironman197268 And at any time in this debate, please do not try and educate me on evolution by saying something like, "Humans didn't evolve from monkeys" cause I totally know how the fairy tale of evilution works.

[ironman197268]

@Helge129 Evolution is not science, it's a fairy tale, and it's as far from the truth as you can get. I wasn't using The Bible as evidence, and even if I was it's not weak minded at all, that's just something on your wish list. You might want to delete your comment about evilution being possible in under 10,000 years, cause if your cronies see that they're going to flip out on you. Nylonase is a Joke!! I want to see baby snakes born with wings, monkeys born with human feet, etc...

[Helge129]

@Helge129 Even without the fossil record, even if the Earth was less than 10.000 years old, evolution would still work. It's been directly observed. One good example being nylonase. A mutation added I think 275 new genes, which alllowed a protein to be synthesized that allows the bacteria to digest nylon. This Is new information.
