Many anthropologists argue that increasing brain size in our ape-like ancestors was the major factor in humans developing lifespans different from apes. But the new computer simulation ignored brain size, hunting and pair bonding, and showed that even a weak grandmother effect can make the simulated creatures evolve from chimp-like longevity to human longevity. The simulations measured the change in adult longevity — the average lifespan from the time adulthood begins.

The new study found that from adulthood, additional years of life doubled from 25 years to 49 years over the simulated 24, to 60, years. Human females often live decades past their child-bearing years.

  1. A recent simulation by other researchers said there were too few females living past their fertile years for grandmothering to affect lifespan in human ancestors. The difference in how fast the doubling occurred depends on different assumptions about how much a longer lifespan costs males:

  2. The findings showed that from the time adulthood is reached, the simulated creatures lived another 25 years like chimps, yet after 24, to 60, years of grandmothers caring for grandchildren, the creatures who reached adulthood lived another 49 years — as do human hunter-gatherers.

  3. But as human ancestors evolved in Africa during the past 2 million years, the environment changed, growing drier with more open grasslands and fewer forests — forests where newly weaned infants could collect and eat fleshy fruits on their own. The grandmother hypothesis says that when grandmothers help feed their grandchildren after weaning, their daughters can produce more children at shorter intervals; the children become younger at weaning but older when they first can feed themselves and when they reach adulthood; and women end up with postmenopausal lifespans just like ours.

  4. Pay attention to me! The grandmother hypothesis says that when grandmothers help feed their grandchildren after weaning, their daughters can produce more children at shorter intervals; the children become younger at weaning but older when they first can feed themselves and when they reach adulthood; and women end up with postmenopausal lifespans just like ours.
