>A study of orcas in the North Pacific has revealed that mothers make a "lifelong sacrifice" for their sons.

>Rearing a son significantly reduced a female killer whale's chance of reproducing in the future.

>The energy they need to feed sons appears to compromise their health, leaving them less able to reproduce and raise other young.

>"Mothers sacrifice their own food and their own energy," said Prof Darren Croft from the University of Exeter.

>From their years of studying killer whale interactions, scientists already knew that mothers and sons "hung out" together well into the male's adulthood.

>"They'll even feed their sons salmon they catch," explained Prof Croft, whereas adult female offspring will hunt independently.

>This could, the researchers think, be a kind of evolutionary "bet-hedging", driven by the fact that the biggest, oldest males go on to father many offspring.

>"If a mother can get their son to become that big male in the population, then he's the one that will sire [much of the next generation]," explained Prof Croft.

>It may seem paradoxical that such powerful, intelligent animals remain dependent on their mothers through their lives, but it appears that males simply don't have to become independent, because their mother remains by their side.

>"If my mother cooked my dinner for me every night, perhaps I just wouldn't learn to cook my own dinner," joked Prof Croft.

>"But, indirectly, it does seem to be in a mother's interest."

What a shit explanation. Any mammal with alpha male interactions would benefit from this but it's seen nowhere else.
Also it's not "evolutionary bet hedging" it's "gene propagation bet hedging"... figures an idiot would get that wrong.

Yes, there is probably some evolutionary advantage and that's why this behaviour can persist. But the orca mommy isn't weighing up the pros and cons of different evolutionary strategy for the species as a whole. She catches fish for her enormous son because he is mommy's special boy and she loves him.

Take bio 101

https://en.wikipedia.org/wiki/Devolution_(biology)
"It is possible for small changes (such as in the frequency of a single gene) to be reversed by chance or selection, but this is no different from the normal course of evolution and as such de-evolution is not compatible with a proper understanding of evolution due to natural selection"
Culling genes is normal evolution. This is trivial. Saying it's the opposite of evolution comes from a not having a proper understanding of evolution.

the simplest explanation is cultural.
animals pass on social things. so long as it doesn't kill them off they can do whatever. they can also vary between groups and extended families, as they do with their languages. what makes more sense, the faculty of language learning a pattern according to input, developmental and otherwise. or simple 'instinctive' call-language that remains fixed despite a spectrum of variation between populations of apparently the same species?

asserting muh evolution over every little thing is stupid when variation in behaviour is socially explainable and social explanations are more robust because the social is a range of potential behaviour bounded by biology. we know things aren't like programmed robots. being fixed just doesn't work.

it's likely this orca behaviour isn't universal or universally the same level of dependence. the male orcas can, after all, survive on their own. even as adults they would suck at hunting but would learn. a period of vulnerability that likely most would survive since they're not totally unfamiliar with hunting.

Orcas are interesting because they have some of the most complex social structures among mammals and also are matriarchal. Their groups are called pods and are led by a matriarch.

This article is retarded because if orca pods are led by a matriarch then no shit offspring would stay with their mothers. Males also weigh more than females and thus require more caloric intake. It's like the author didn't even bother to read the wiki page or other summary source.
