Shout out to Peter Kim with the agent based model 

Consisting of an ape-like history to start from 

Then he added grandmothering into the base 

To see if longevity could mutate

As a result, human longevity climbed higher

Operational sex ratio tripled male bias

Which means, there were three times the amount

Of males competing for the breeding females around 

Which can actually be good

Since conjugal bonds depend on
The existing bonds of brotherhood 

Men compete for standing in society

And try to show their value as an ally, constantly

It seems grandmothering ushered in good benefits 

Post-menopausal longevity, early weening and Pushing the rate higher for parents

So thank the grandmothers and let them know they are cherished
