I wonder what could be going on here... #GeneticConfoundinghttps://twitter.com/stefanmolyneux/status/998324840099696645 …

Heritable Heritable ≠ selected for. There is no need to invoke evolution when talking about heritable traits

I was thinking that they were thinking, "a propensity for abortion can't possibly be heritable because it's constantly selected against"
-
Which is moot either way
-
Well you can say that something doesn't have to be selected for in order to be heritable, but it does bring up the question of why that heritable trait would exist
-
Chess skill, basketball ability, hours watching TV, video game playing are all heritable and clearly weren't selected for in the ancestral environment.
-
How do you know what the ancestral environment was like?
@_attlee -
TV was invented less than 100 years ago...

abortion is not a genetic trait, so it can't be selected against
-
I don't think it's unreasonable to say generally, for example, "dying before reproducing is selected against"
-
vacuous
-
We can get more specific and say things like "susceptibility to dying from the common cold is selected against". Maybe you'll agree that's also valid, but I don't really see your point.

“aborted fetuses can’t reproduce” is informative?
-
In the absence of any other considerations it also reduces the number of offspring the mother has, but either way nobody said it was that insightful
-
I mean, the point was, in fact, that traits leading to more abortions could actually be selected for despite the abortions themselves
-
where's the confounding?
