Walking with Monsters. Life before the dinosaurs

Evolution mainly happens through mutations, and if the mutations are benificial, the specimens with the mutated DNA will usually pass on the DNA more likely than those without the benificia; DNA.

 

For example, if on bacerium forms a protection against anti-biotics (through a genetic mutation), it will be allowed to reproduce where no other bacteria can survive. Thefore the amount of anti-antibiotic bacteria will increase, and the "normal" bacteria will decrease.

 

 

At least, thats what i gather from GCSE biology and a bit of logical thinking.

Evolution is of course happening. o.O It can't stop happening. :-/ It's impossible... You're taking it like natural selection is the only thing that pushes evolution. lol A species surroundings infact is probably a bigger factor and is what will cause faster evolution. I mean if there was another ice age you think that humans wouldn't evolve to fit the new climate? Of course they would.. It's the reason that there are differences found throughout people around the world..... The only reason that evolution isn't SO noticable in humans is that there hasn't been as massive change in the climate of places people have been living in.....

 

Blah rambling on.... v.v Can't be bothered to finish this post now. XD
