@PhoenixHelix animals evolve because of natural selection, it take millions of years for new species to develop. For example, if there is a species of fish, and in an egg laid one day a genetic mutation occurs that causes this fish to develop a longer tail which means that it can swim faster. This makes it more successful at catching prey than slower fish and so this fish is more likely to survive and produce offspring, and hence the genetic information that gave the fish a longer tail continued

@PhoenixHelix what makes up DNA are proteins- which make up amino acids. The order of these proteins in the genome is what determines the traits that are present in an organism. We can clearly see how we are genetically different from other animals, and can tell two different humans apart from their genes. Please do some research on the subject before spurting ignorance all over the comments.

@HighProphetOfRegret Shows how much I know. I'm gonna go back to listening to Walk The Dinosaur

@jake1112222555 That is not really what "fittest" means in biology. "Fittest" means best capable of producing *viable* offspring.  It doesn't mean the creatures that are able to best dominate other creatures because they're smaller.

@lopzag Oh and for people who don't understand what natural selection means, it's pretty much survival of the fittest. Imagine a group of bugs, any bugs. Brown and green. The population can't grow forever so birds or small animals will eat them. Let's say the green one's because they are smaller. As they are eaten, the brown ones will start to become dominate and there will be no more green bugs. Get it.

@luongrobert4 well seems as if you already did drop out of education ....i guess you think that the earth is only a few thousand years old also...

@Tahkaullus01 yea :(



[Tahkaullus01]

@PhoenixHelix Huh? Excuse me but the fact that there are dozens of different shark, jellyfish and scorpion species kinda makes your point moot. Yes there is little change, but there IS change. They are not the same species they were sixty five million years ago. There were no Great Whites in the young atlantic, they had to come from somewhere.

[Tahkaullus01]

@giles166 in that case we're actually doing our species a great disservice. We keep this up, there'll be no truly adapting humans left and when all the stuff we rely on goes to shit (fossil fuels, electric light etc) the human race could very well go extinct. Scary huh?

@giles166 I think that natural selection is reversing for us, actually. Part of why there's so many stupid people out there...XD

[giles166]

@jaymorpheus11 humans are not allowing for natural selection, we will stay the same until te end...
