Alan Rogers explained that in 1994, I think. To quote from a recent post 
of mine:


"In a now-famous paper, Alan Rogers once argued that sexual 
recombination was largely

responsible for temporal discounting via kin selection. If people have, 
on average, around

two kids each of which share half their genes, then at a similar point 
in their lives,

investments in those kids are around half as valuable to a parent as 
investments in

themselves. In the case of the kids, half of any investment by a parent 
would go to

a bunch of unrelated genes from somebody else. If a generation is around 
25 years

(for women) and 30 years (for men). That results in around 2% temporal 
discount annually."
