The big secret:
“Homo sapiens” are hybrid combinations of different species that have long disappeared. “Non human hominids” are frequently groups that mixed with Homo sapiens. Large variances in human populations come from different hybrid compositions
- revicon 3y agoThe statement "Large variances in human populations come from different hybrid compositions" seems a particularly provocative statement. Is there a source where this comes from?
- PM_me_your_math 3y agoI don't see how. Many of us have Neanderthal DNA. Objective facts are only considered (falsely) provocative if the provoked has an axe to grind, or a pursuit other than objective truth.
- r13a 3y agoI definitely see how this statement is provocative when overwhelming scientific consensus underlines a very low variance in human population that is NOT explained by variance in traces of non-homo sapiens DNA.
- hexator 3y agoYou imply that it's a significant percentage though, which is highly debatable.
- tsimionescu 3y agoThere are no large differences between human populations though: that is the provocative part of the statement.
- hackinthebochs 3y agoI'm not sure what part specifically you take issue with, but this provides some relevant citations: https://en.wikipedia.org/wiki/Interbreeding_between_archaic_and_modern_humans https://en.wikipedia.org/wiki/Interbreeding_between_archaic_...
- shrubble 3y agoAre you referring to those with Denisovan vs those with Neanderthal vs those with neither?
- greatpostman 3y agoThere’s other unidentified populations. They just can’t find bones to isolate the dna
- alcover 3y agoI found this abstract maybe : https://www.pnas.org/doi/abs/10.1073/pnas.1109300108 https://www.pnas.org/doi/abs/10.1073/pnas.1109300108 "(...)an unusual segment of DNA that extends for >31 kb on chromosome 4 seems to have introgressed into modern Africans from a now-extinct taxon that may have lived in central Africa" That's fascinating stuff. Says introgression may have occured 35ky ago from a branch that split 700ky ago.
