Abstract

The Northern Dispersal Route (NDR) and Southern Dispersal Route (SDR) are hypothesized to have been used by modern humans in the dispersal out of Africa. The NDR follows the Nile into Northeast Africa and crosses the Red Sea into the Levant. The SDR emerges from the Horn of Africa and crosses the Bab el-Mandeb into southern Arabia. In this study, we analyze genetic data from populations living along the NDR and SDR to test support for each dispersal route. We genotyped 90 Yemeni samples on the Affymetrix Human Origins array. We analyzed these data with published data from Levantine and other southern Arabian populations as well as 157 comparative populations for a total sample size of >550,000 genetic variants from >2,000 individuals in >160 populations. We calculated outgroup f3 statistics to test how Levantine and southern Arabian populations relate to African populations living along the NDR and SDR and to other non-African populations. We find that Levantine and southern Arabian populations bear similar genetic relationships to both African and non-African populations, thus providing no support for the use of one dispersal route over the other. Our results are consistent with a history of gene flow between the Levant and southern Arabia. Consideration of genetic, archaeological, and paleoclimate data provide a slight edge for the SDR but, ultimately, more data are needed to definitively identify which dispersal route out of Africa was used.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 21. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 31 October 2023.
All research outputs
#1,793,879
of 25,382,440 outputs
Outputs from American Journal of Physical Anthropology
#488
of 3,878 outputs
Outputs of similar age
#34,340
of 323,373 outputs
Outputs of similar age from American Journal of Physical Anthropology
#11
of 45 outputs
Altmetric has tracked 25,382,440 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 92nd percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 3,878 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 15.1. This one has done well, scoring higher than 87% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 323,373 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 89% of its contemporaries.
We're also able to compare this research output to 45 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 75% of its contemporaries.
