Even professors in higher education teach this wrong. It's dangerous, backwards and just plain incorrect.
I need to get this off my chest. Often natural selection is presented on an individual level. We are presented with two offspring. One has lots of babies, the other has none." Which is the fittest? We are told "Well obviously it's the one who passed on its genes!"
Some errors are made here. One error made is forgetting that all species share most of their genes. Meaning that it's the nearly the entire species genealogy being passed on, not simply the individuals.
Another error is assuming those who do not have offspring are not fit for the survival of the species. In social species, these individuals without offspring may have traits that allow them to care for the offspring of other members of their species. "It takes a village to raise a child" after all. The childless members of the species may have more time to search for food and build shelter, etc. They ensure the fitness of the species by increasing the survival rate of the species as a whole.
The majority of bees and ants, for example, cannot have children, and this is integral for the species survival.
Finally, genes are not the only thing that are passed between the individuals of a species. Again, the tool using methods of a childless member of a chimp troop may be passed on to the entire troop through observation, and carried on through generations. Orcas teach each other survival techniques that pass on throughout the whole pod.
Anyway, I believe the way we teach about the natural world is poisoned by this old fashioned fascist idea of "families not society" and as our community structures are stripped away and people find themselves too poor and overworked to have kids, the social aspect of our survival becomes clearer than ever.
Survival of the fittest is also seemingly an invitation for people to project toxic masculinity based ideals onto animals, immediately imagined to be survival of the strongest, fastest, and meanest. Meanwhile actual adaptations are like... absorbs more calories from the most common kind of nut on this island, slightly lazier during the season when food is scarcest, or slightly sexier to other sparrows.
My sister dated a guy who believed this. He once said to me, "If evolution is real why isn't every animal as big as a T-Rex?".
In fairness to him, he grew up in a cult where education was done by whoever felt like doing it that day.
Surprised he thought dinosaurs were real
I remember reading one about femboy Orangutans and Octopus. They're males of such low T that the Alpha doesn't perceive them as competition. He lets all the ladies hang around in in his domain, and that's where the femboys slip in.
They're boning behind the scenes without the Alpha noticing, to extent that sometimes the alpha tries to fuck one and is then like wait... this is a dude.
(they're called sneaker males apparently)
