CW: nature and violence = natural?
@freeschool right, I was talking about the concept of deep time, as described in the Wiki article. The reason for running them together as one word is simply that there's no way to tag phrases as far as I know.
The origin of the post was a conversation I was having elsenet about why modern #humans show evidence of #maternal #inheritance from #Neanderthals via #mitochondrial #DNA, but no evidence of #paternal inheritance via the Y #chromosome.
Their explanation was basically "our ancestors killed all the men and took all the women." Which is possible, of course: there are certainly plenty of examples of that in recorded human #history. But I have hard time believing it's the *only* thing that happened between two species (or subspecies: the line is fuzzy) that interacted with each over over tens and perhaps hundreds of thousands of years.
Another and IMO more likely explanation is that #hybrid #fertility is sex-linked. e.g. the rare #fertile #mules are always female. If the same applied in this case, that would explain why the #Neanderthal Y chromosome disappeared in mixed #human populations.
There are definitely applications to modern behavior. 🙂 But really, I'd mainly just like people to get away from always assuming the bloodiest possible explanation for observed #biological phenomena, whether in humans or any other animal.

"Post-spawning care of nonbrooded embryos in the #Colossendeidae is an exciting finding..it may represent an evolutionarily intermediate strategy between free-spawning & the #paternal brooding exhibited by most other groups of sea spiders..mating stacks of more than two individuals also raise interesting questions about the potential for male competition for #fertilization..more detailed observations & identification of the sex of individuals in mating groups are needed"

Once again, I am one of the great throat-clearers. I take after my father in this regard...

@tanweerdar
The truth is I have no
#Paternal or parental bone in
My body. My parenting skills
Are imperfect, inadequate, &
Made up on the fly. I don’t need
An invented commercial day to
Celebrate how hard we work to
Make this family function as
Well as it can. All we want
Is for all the others to be happy.
Sometimes it works, & often
It doesn’t & hurts instead.
What I really want is to be a
Person who cares, not a parent
Put into some compartment that
Says old & tired & past it.
