Evolution
... • Evolution is an undirected process, constrained – by physical laws (such as gravity) – by genetics (which might, for example, encode the directions for building breathing organs in a particular way), and – by the environment (which might not, for example, contain a niche for a large, slow-moving, ...

How does evolution occur by natural selection?
... • When bacteria are exposed to an antibiotic there is a chance that a few will have a gene that makes them resistant. • The bacteria WITHOUT the resistance will be killed, while those that are RESISTANT will survive and pass on their genes for antibiotic resistance. The antibiotic is the selecting a ...
