Girls, find an older guy and guys, find a younger girl... By Crobar in Neurognosis October 10, 2007

Why? Well, to boost the lifespan of subsequent offspring of course! Humbug you say? Nay, verily I speak of research! Yes, research my friends!

Okay, I'll chill on the theatrics. But I'm not kidding about the older guy/younger girl thing. A new study published online in PLoS One by Shripad D. Tuljapurkar and crew found that older men mating with younger females eliminates a higher mortality, what they called the "wall of death". Evolutionarily it will serve to raise the lifespan upper boundary for later offspring.

So there you have it folks! So next time you see that older guy with a younger woman, don't scoff they're benefiting the entire species!
