Father's age influences rate of evolution: 90% of new mutations from father, chimpanzee study shows

A few quick tidbits from the story:

In humans each extra year of paternal age results in ~ two extra mutations.
Mutation risk is linked to father’s age because the sperm lineage in males keeps dividing, while females have all the eggs they are ever going to produce present at birth.
It’s believed that chimps may produce more (cycles of) sperm than humans, and thereby amplifying this affect. Their testes are actually about three times the size of a humans (on average).
This effect is greater in chimps than humans by 1.5 times. In chimps, about 90% of new mutations come from the male… whereas in humans, fathers account for about 75% of new mutations.
