      Why were English racehorse breeders so successful in developing fast Thoroughbreds in the early 18th century? They believed that "heredity was far more important that development or environment". Yikes! Hereditarians!pic.twitter.com/CH60L3E8Q0

      Hm... Arguably technically wrong (aren't all the key racehorse heritabilities <50%?), highly suspicious 'blood lineages' aside, but also practically correct if it led them to focus on durable gains from selective breeding rather than tweaking training regimes w/minimal effects.

      My vague impression is that racehorse breeding is less scientific to this day than less glamorous fields like milk cow breeding, perhaps due to earlier development of close-enough proto-scientific rules of thumb in horse breeding.

          I would agree, based on the little I've seen of race-horse research (eg https://en.wikipedia.org/wiki/Talk:Dutch_Warmblood#Genetics … ). Cows breeders are hard to beat. But I think it's due to being a romantic glamorous hobby, where participants are often content to turn a big fortune into a small one amusingly.

          eg from today: https://link.springer.com/article/10.1186/s12863-018-0670-3 … no SNP heritability; no full PGS (just genome-wide hits); no genetic correlations; no heldout or validation cohort; no consideration of measurement error... It seems to be a lot better than other horse GWASes but still not Nature material.
