Surprising article. The conclusion that ear protrusion (yes, that's a thing) has no genetic basis is of course not impossible, but seems unlikely. It would require another data set to establish it.
- z33k 3y agoI have a lot of ear protrusion, which is even more notable due to my large ears. Having seen old pictures of my great grandfather last weekend, it seems clear whose genes for large protruded ears I inherited.

- dTal 3y agoWorth noting that not all heritable traits are reflected in DNA, thanks to epigenetics.
- crackedbassoon 3y agoThey estimated SNP heritability via GCTA.
- indeed30 3y agoCouldn't it be possible for ear protrusion to be uncorrelated with the other variables but still have a genetic basis - presumably by depending on a set of genes with little overlap over the ones that govern size?
