How does mutation work in evolution?
Mutations are basically copying mistakes during the replication of the genome. Such mistakes occur because chemistry is basically a messy process, with all those little molecules flitting about more or less randomly. Mechanisms have evolved to protect the cell and the genome against the worst of all that randomness, but some copying errors will always find their way into offspring. This is what provides the genetic variation that natural selection works on.
