Effects of Father Loss
 ... are not just emotional, but biological.  It shortens a child's telomeres.  While death has the biggest impact, divorce or incarceration have similar effects.  Shortened telomeres correlate with shortened lifespan and worsened health.  Now consider that in light of policies from prison to foster care.  Losing a parent is the worst thing that can happen to a child.  If they are not literally in immediate risk of death, everything else does less damage.  That sucks, but it should be used to find other ways of solving family and social problems that do not butcher children's lifespan and health at a cellular level.

No mention was made of mothers.  Likely the effects parallel those of father loss.  I would not be surprised if they are worse.

It's also claimed that the reason why women tend to live so much longer than men is because of the grandmother effect--grandmothers used to put lots of time into helping raise their grandchildren thus ensuring that more of their grandchildren survived to adulthood--which also ensured that the genetics for women living longer lives were passed along as well.

Yes...

It's a very plausible and practical theory that works well in social species. But only a few have actually evolved grandmothers that menopause and therefore devote their energy primarily to grandchildren rather than their own babies -- and they're all higher species.

Re: Yes...

I'd give a donut to find out how the researchers figured out that female killer whales go through menopause just as we do!

Re: Yes...

Presumably by observation. Orcas are easy to identify by their markings, so you can tell if a female has a new calf each year. If older females stop having calves for a number of years before they die, and remain in their daughters' pod, menopause is a logical conclusion. Another option is autopsy of dead whales.

Re: Yes...

And that makes sense. Thanks!
