Anyway one time I was trying to put evolution in a logical perspective. Well I was wondering why we evolve in the first place. I could think of a couple answers. They were: need, curiosity, and want for perfection, which is sort of falls into the second category.
​
Evolution occurs because lifeforms are imperfect replicators who sometimes die before they can reproduce.
​
There is no 'need' for evolution, it's just something that occurs.
​
Evolution acts on pupulations, which have no desires or curiosities.

Re: Need, want or curiosity
Chronos,
Are you saying that evolution occurs for no reason?
​
No, I gave the reasons why evolution occurs.

Re: Need, want or curiosity
So I am asking about a situation where changing from one species to another would benefit better than in-species yet still allow enough time for it to work
​
All that will happen from one generation to another are small changes. You're never going to see a "horse giving birth to a duck" type situation. If an isolated group of beavers that live in a cold environment are more likely to survive with thick fur and develop thick coats over a few thousand generations, we might classify them as a new species.
​
For the record, scientists have documented quite a few (at least several hundred) instances of speciation/macroevolution occuring.
