Did you know that white #hair can sometimes revert back to having colour? This article talks about research in why hairs can change colour.
But my thought is -- they looked just at people. If you look at the hairs on your patterned dog or cat you'll find individual strands of hair that are multiple colours -- from top to bottom. I had a tabby #cat whose stripes that were dark on the surface, were lighter in the middle and almost white at the root. I guess that means that #pigment can travel through hair? (I'm guessing, I haven't actually seen the research). https://getpocket.com/explore/item/gray-hair-can-return-to-its-original-color-and-stress-is-involved-of-course

previously unrecorded gastropod species was used as bead 70 ka.
The #RadicalAnthro team does not think the authors (d'Errico et al) are getting the relationship right between #MSA ochre #pigment use and beads. We very much doubt initial usage of #ochre was 'utilitarian' and subsequently became symbolic. Take a look at our thread on the #Dapschauskas paper on ochre as a ritual tradition here https://c.im/@RadicalAnthro/109540854804414843
