      Nah, all non-Africans (white, asian, indigenous, etc) are 1-3% neanderthal, while Africans are 0.5-1%. All humans have some trace amounts, but most of it is meaningless genetic noise. Neanderthals had genetic issues due to inbreeding, so tangible effects of their DNA were selected out of our gene pool

      We used to think Africans are 0% neanderthal bc neanderthals exclusively lived in Eurasia. Now we know that’s not the case, since most modern Africans have ancestors who spent thousands of years in Eurasia before migrating back to Africa. East-Africans have ancestors who spent up to 30k years in Eurasia (sapiens first left Africa 60k years ago), long enough to adapt light-skin and become what we would consider “white people,” before migrating back to Africa and eventually regaining melanin. Goes to show how bs the idea of biological race is

      Also, the vast majority of humanity’s genetic variation isn’t between groups, but rather existing in all groups (e.g. genetic neurodiversity, like autism or ADHD, being found roughly equally across all ethnicities)
