      Wael Retweeted Tania A Reynolds

      At the NorthEastern EvPsychSoc conference 2019, PhD candidate @SeveriLuoto presented work proposing a theoretical framework for sexual selection in humans. It got attention for this bit on cold and intelligence/innovationhttps://twitter.com/TaniaArline/status/1135254935858221056 …

      Wael added,

      Tania A Reynolds @TaniaArline
      Among 122 countries, colder climates predict higher intelligence, and ultimately, stronger economic complexity. Research by @SeveriLuoto suggests winter imposed selective pressures for creativity and innovation. #NEEPS2019 pic.twitter.com/Od6bvyZ8l9

      Wael Retweeted Will

      Predictably, this bit in particular got a lot of criticism. One critic was @Evolving_Moloch, who called the cold claim "wildly unpersuasive" to which many users tweeted agreement. So is it just BS after all?https://twitter.com/Evolving_Moloch/status/1135474709955371009 …

      Wael added,

      Will @Evolving_Moloch
      There are more words in this paper devoted to discussing American cars and the novel Pride and Prejudice than there are actually attempting to demonstrate the proposed link between 'cold winters' and selective pressures for more innovation. https://twitter.com/SeveriLuoto/status/1135275663538216960 …

      I read the article (whopping 56 pages) and found a few flaws. My main problem is w the correlation between economic complexity today and cold environments, which cannot be used to make evolutionary arguments. Whites did not evolve in hot Australia etchttps://www.researchgate.net/publication/329627448_An_Updated_Theoretical_Framework_for_Human_Sexual_Selection_from_Ecology_Genetics_and_Life_History_to_Extended_Phenotypes …

      But while I'm always glad to see (constructive) criticism in aca, a number of criticisms by Will, though popular, reveal a clear lack of familiarity with the areas of evolutionary science he's criticizing. Since many seemed swayed by him, I wanted to correct the record.pic.twitter.com/ennJguc9IV

      First, Will thinks that because cold = harsh, hot should also select for intelligence because hot = harsh. In reality, it's not only harshness but unpredictability that imposes an extrinsic mortality regime favoring mating effort over somatic effort. Ref is Chua et al. 2017pic.twitter.com/R5UuypUmp8

      Explanation: if your threats can be prevented (intrinsic) then investing energy in prevention will improve biological fitness. If threats are constant and can kill randomly (extrinsic) then investing in immediate reproduction will be more efficient for fitness. It's simple stuff.

      This isn't particular to evpsych or life history theory - it's actually a theoretical consensus in evbio. Here, Richerson, Boyd, and Henrich (now head of Harvard HumanEvBio) make the same point in an article on gene-culture coevolution.pic.twitter.com/7jBmKfDAZ6

      Okay then, SO WHAT ABOUT THE NEANDERTHALS, HUH? Great! I'm glad you asked. They're actually the best example we have for the climate as a selection pressure on divergent brain evolution (size and function). This is from Beals et al. 1984, who discount racism on page 1.pic.twitter.com/ILqpraoyjh

      Again, there's stuff to critique in the original paper by @SeveriLuoto. But the climate-evolution-brains connection wasn't even an original argument - and because critics didn't do their homework, creepy race-obsessed weirdos are leaping in to claim a win. Not good for science.pic.twitter.com/NdpsBEqilr

      This is in no way a 'callout' of @Evolving_Moloch, who is a great and highly productive anthropologist. But it DOES show that when ppl don't do homework before criticizing, bizarre raciophilic evolution deniers and innocent bystanders are affected by our momentary ignorance.

      On a high level, I think this problem relates to our cognitive bias toward thinking in groups. When ppl say insane things like 'evolution is racist' and 'Donald Trump is a great president' they're probably afraid that if their cause is only partially right, it isn't right at all

          I think our best shot is to negotiate point-by-point on both causes we support and those we oppose. Trump having a few good policies doesn't discount his character flaws, and the noted issues with @SeveriLuoto's essay doesn't discount influence of climate on human evolution/Thredpic.twitter.com/YX9lW3ZH4f

          Forgot to include the actual Tweet on the neanderthals, but many people were getting confused in the multiple threads that spawned out of @TaniaArline's OG tweet, which is why I brought them into this thread. #NEEPS2019 is a safe and neanderthal-inclusive spacepic.twitter.com/HqnrH4EEMG
