How does evolution happen? How does life improve on itself automatically?

My question is this:

I realize that species develop skills, abilities or phyical changes in response to a need in the environment. I want to know what "tells" the genes (?) or DNA (?) that this change needs to happen in the next living being? How do the genes (?) "know" to make this change?

In nuclear fusion, is it heat or X-rays that causes the fusion reaction?

The closest I can get is that a fission reaction takes place and the X-rays are then focussed on the next component ie deuterium/tritrium in an eliptical sphere. However I thought X-rays couldn't be 'bent'. Any H-bomb makers out there?
