How did you determine when evolution started? Why leave out the pre-galaxy hydrogen gas? I may sound absurd, but the question is still valid: "How did you determine when evolution started?"
I don't think any scientists can give you some definite time
when evolution started. What you will probably here is that evolution started when an individual who varied in their heritable traits within a population was able to produce offspring. That these offspring also varied in their heritable traits and had the potential to produce more offspring than the environment could support. This overpopulation led to a struggle for existence among the variant memebrs of the population. Those offspring whos traits better helped them to survive and reproduce in thier environment were able to leave a disproportionately larger number of viable offspring. This differential reproductive success of some offspring over others meant that those traits passed down were more likely to appear in subsequent populations.
The TOE is not concerned with
how or
where the first organism came about. The [i]evolution[/] of the universe via
the big bang is not concerned with the evolution of life. They both may hint at possible causes or relationships but they are seperate theories. You may wish to peruse a biology textbook again. We might at that time be able to answer any questions you have more succinctly, and you, as well as we, may understand more about what we are discussing.
