Interesting topic! The vitamin D connection is very tangible: up here in the Nordic countries all kids are supposed to get supplemental vitamin D - and parents of kids with dark skin get a higher dosage to give the kids to offset the lower production in the skin.
Good introductory video to the topics of hair density and skin pigmentation. Would be great to see follow-up videos covering: identification of the different genes that produce similar or different pigmentation among populations; how pale skin is beneficial in low-UV latitudes; and dates for the evolution of pale skin in different populations.
It is mentioned in the lecture that similarly dark skin can come from different gene variants. Are they mutually exclusive - or could one theoretically have more than one variant of high-melanin genes? i.e. combine into an even darker skin tone? or into a even lighter skin tone with different genes from different groups with lighter skin, for that matter? Or does it simply not work like that?
We came home and raptors so we do not need to have that much hair because we were around so that obviously called perspiration our hair growth throughout our skin we didn’t need air I don’t have to drink to do with expression of selecting our muscles or dominoes it is climate related to that one soon when the cold is a Clement and less amount and we have that’s for the Caucasian came into place and for the northern hemisphere to stay in the Southern Hemisphere. And Caucasian are the last to eat while they were the last to Luther Melanie so they are basically a new species Homo sapiens
wonderful presentation, thank you for sharing

That was well done and very interesting.
New Information for me. Thanks
This is PRECIOUS. Always love seeing anything from Nina and I hope to continue seeing more!

Excellent explanation of skin color, thank you! This video should be required to watch in middle school.
Fantastic lecture. CARTA always teaches me something. 💥💥💥
Very interesting information.
i love her hair...so full of wisdom
Fascinating 🤔
This woman is way ahead of her time.
I'm just here to give you some engagement for the algorithm. I'm not smart enough to have anything to add lol
Being self-aware makes you smarter than most

Does this give pause to those who discriminate against the dark skinned of humankind? It should!
And she's a alien hybrid, but that's another video 😀
