Oh dear God.. do any of you have the slightest clue about evolution?
Yes, we are currently evolving. Species are ALWAYS evolving. There is no 'end point', no perfect creature.
Evolutionary theory goes like this, for those of you that do not know...
Animal mates and reproduces offspring. In each offspring, there are mutations in their genes that produce certain characteristics that may or may not be beneficial for survival. If the characteristics are beneficial - for example, being able to run faster - then the animal has a greater chance of survival than other animals in it's species (running away from predators, in this case). This means that the animal has more of a chance of reproducing than its peers; and when it does reproduce, the trait of being able to run faster will be passed down to it's offspring.
Animals don't just decide to 'turn off' evolution because they are satisfied with their current state.. that's nonsense. If you do not know what you are talking about, don't act like you do.
