"pls send me your steps in evolutionary biology(or its simulation)"

I'm not sure if you're talking to me. I actually was looking to see if I still had the code somewhere. I'm unable to find it so far. But the algorithm is pretty simple - as I said it was outlined in an article by David Fogel in IEEE Spectrum.

"What is evolutionary computation?"

The general algorithm he gives is:
Initialize the population
Create offspring through random variation
Evaluate the Fitness of each candidate solution
Apply Selection

I'd offer to write the program again and send it to you, but I'm kinda busy at the moment. It's surprisingly easy, though, if you'd like to give it a try. Take a look at the article - everything you need is in there.

(Again - I don't claim it's proof of anything. It's just an illustrative tool to help understand the possibilities of 'random' variations in populations acting under constraints.)
