I need people to help me out with these questions
1.)Bacteria can evolve into two every 20 minutes, this enables them to evolve very rapidly...explain why?
2.)In order for organisms to become fossilised, sediments must cover their body parts, explain why?
3.) Explain why, as a general rule, deeper rock layers are older than ones nearer to the surface.
4.) Suggest why younger rocks contain fossils of organisms which are similar to those still living today?
