Bret Weinstein is a hero of free thought, but in trying the “I found the flaw in Darwin” move, he makes a common error: touting a benefit to the group in the future w/o considering the cost to the individual in the present. https://whyevolutionistrue.wordpress.com/2019/09/20/bret-weinstein-goes-awry-when-claiming-that-neo-darwinian-theory-is-missing-an-important-part/ … via @Evolutionistrue
I've argued since the mid-90's that what @BretWeinstein calls 'explorer mode' is largely sexual selection helping populations explore the space of possible traits & escape local optima; e.g. see these papers:

2) https://www.primalpoly.com/s/1997-biodiversity-sexual-selection.pdf …

@Langerhans_isle LMAO, got a notification for this thread via you & I love how Geoffrey Miller shows up to talk about sexual selection. There's a running joke about how he sees sexual selection in everything. -
And now he blocked me. I have never said anything to him or about him.

I’d suggest it is entirely reasonable that there is an optimal level of phenotypical gen-to-gen random error for any given environmental niche (which includes size of niche, etc). But seems unlikely to include something to constrain phenotypic parameters of randomness..
-
FWIW: good summary (albeit 20 yrs old) of some of args environmental stress may increase phenotype variation, either via gene mutation or greater noise in gene translation to phenotype. Doesn’t seem unreasonable, but wld be hard to pin down (falsify). https://academic.oup.com/bioscience/article/50/3/217/241447 …pic.twitter.com/bUnVq1vgm0

Read the 1997. Cool. See that "apostatic selection" and "intrinsic" sensory or psychological preferences function as diversity accelerator or "peak-jumping" drivers. I wonder if
@BretWeinstein will consider these sufficiently directed (vs. just scattershot) to fit his bill?Thanks. Twitter will use this to make your timeline better. UndoUndo

Isn’t individual variability another form of
@BretWeinstein’s explorer mode? You will literally get some individuals that, by personality traits, are drawn to explore and take risks more than other individuals.Thanks. Twitter will use this to make your timeline better. UndoUndo
