human migration out of Africa - 2023 Chicago Open

Question

Note to moderator: Please read the answerline carefully.Description acceptable. A 2023 paper by Ragsdale et al. attributes high variation arising from this event to a “weakly structured stem.” This process is the earlier of the two main case studies in the paper that introduced the software dadi (“daddy”), in which a 14-parameter model that describes this process is fit to YRI, CEU, and CHB data sets. A southern coastal dispersal during this event may be the source of sibling groups M and (*) N, which split from haplogroup (10[1])L3, whose time of divergence is an upper bound (10[1])of approximately 70,000 years ago on estimates of the time at which this event (-5[1])began. (10[1])Geographic variation in archaic admixture is likely due to contact with Neanderthals occurring primarily (10[1])after the onset of this (10[1])event. For 10 points, name this process by which Homo sapiens spread (10[2])from its original (10[1])habitat. ■END■ (10[1])

ANSWER: human migration out of Africa [accept out-of-Africa hypothesis or out-of-Africa model; accept answers that describe the departure of anatomically modern humans from Africa; accept Homo sapiens in place of “humans”; prompt on answers that describe human migration; prompt on descriptions of human migration into non-African regions like Asia or the Middle East, or out of regions within Africa like Sub-Saharan Africa, by asking “What is the broader trend in that human migration?”; reject answers that describe other hominins, like “Neanderthals,” in place of “humans”] (The names of the data sets in the second sentence stand for “Yoruba in Ibadan,” and “Central European in Utah,” and “Chinese Han in Beijing.”)
