No other placental mammal that we know of prefers one side of the body so consistently, not even our closest primate relatives. But being right-handed may have deep evolutionary roots in our lineage. And yet, being a leftie does seem to come with some unexpected advantages.

Big thanks to Julio Lacerda (https://twitter.com/JulioTheArtist​) for the excellent right-handed Neanderthal illustrations!
