What is the origin of recessive genetic traits?

Lisa asked the Naked Scientists:
   
If we are all basically from the same lineage, where did recessive traits start
from? If these traits were something that we adapted or we mutated, could more traits pop up in the future?

What do you think?

We're always up for mutations. It's just that nearly all of them are not favourable.
