We present genome-wide data from 41 individuals associated with Later Stone Age, Pastoral Neolithic (PN), and Iron Age contexts in what are now Kenya and Tanzania to examine the genetic impacts of the spreads of herding and farming. Our results support a multi-phase model in which admixture between northeastern African-related peoples and eastern African foragers formed multiple pastoralist groups, including a genetically homogeneous PN cluster. Additional admixture with northeastern and western African-related groups occurred by the Iron Age. These findings support several movements of food producers, while rejecting models of minimal admixture with foragers and of genetic differentiation between makers of distinct PN artifacts. [/QUOTE]and the conclusion [QUOTE] Conclusions Genome-wide data from 41 ancient eastern Africans show that archaeological complexity during the spreads of herding and farming is also reflected in genetic patterns, which indi-cate multiple movements of and gene flow among ancestrally distinct groups of people. We identifythree components of ancestry harbored by ancient pastoralists and propose a se-quence of admixture events to explain our observations; fu-ture archaeological and ancient DNA research in the Turkana Basin, the Horn of Africa, and other parts of northeastern Af-rica will be necessary to confirm the earliest stages of the spread of herding into the region. At the other end of our timeframe, we show that multiple admixture events impacted Iron Age groups associated with heterogeneous economic, cultural, and linguistic patterns. This complexity can be fur-ther explored through additional comparisons of genetic and archaeological diversity. Ancient DNA offers a new source of information about eastern African Holocene prehistory, and an important next direction is to integrate this information rigorously with insights provided by the longer-established disciplines of archaeology and linguistics. [/QUOTE]They dont mention anything Eurasian in the introduction or conclusion and in the rest of the article they mention Eurasians just once and Europeans just once And if we look at the Science Daily article about this journal article they don't mention anything about Eurasia, Europe or the Middle East. And the same article published in Sci News: https://www.sciencedaily.com/releases/2019/05/190530141445.htm [b]Ancient DNA tells the story of the first herders and farmers in east Africa[/b] _____________________ they don't mention anything about Eurasia, Europe or the Middle East. [/qb][/QUOTE]Either you're purposefully acting dense, or you're being disingenuous. I criticized two things: Conventional belief and the lack of effort to dispel, or support those beliefs by this study. [i]"How food production first entered eastern Africa ~5000 years ago and the extent to which people moved with livestock is unclear."[/i] <-- Was this inquiry made clear by this study? food production [i]entered[/i] east Africa? from where? They used an ancient near eastern population to model the highest proportion of the ancestry in their PN cluster. And don't atleast address the popular theory of PN culture and AfroAsiatic being brought from the near east. You don't think that it would be important to address that in some way shape or fashion now that we have nearly 3 dozen PN people of east Africa? [/QB][/QUOTE]
