But, since I am so unlearned, please be so kind as to start with a definition of evolution if you can.

Through the process of replication, heritable difference, and natural selection over multiple generations, interbreeding populations change to adapt to changes into their environment. When a population splits into two separate isolated groups, each group will change in different ways as they adapt to different changes in their environment. If they stay isolated long enough, they will gradually become so different that they no longer interbreed if they eventually come back into contact with each other. Thus, a new species.

This is not speculation?

You ahve not started at the beginning, how about you tell em where it all started, after all, I am but a simply minded Mainer, unable to grasp things started in the middle.
