Africa: Where Did the First People Come From? the Case for a Coastal Migration From Southern Africa: [The Conversation Africa] The origins and migrations of modern humans around the world are a hot topic of debate. Genetic analyses have pointed to Africa as the continent from which our ancestors dispersed in the Late Pleistocene epoch, which began about 126,000 years ago. Various dispersal routes… http://newsfeed.facilit8.network/TP066g #Africa #HumanMigration #GeneticAncestry #Pleistocene #CoastalMigration

Some #FoodForThought from the #researchpaper linked above💡💡💡

“Importantly, in my view, the term ‘genetically similar to’ also helps to avoid the assumption of homogeneity within labels; ‘similar to’ does not imply ‘same as’. Similarity-based sample descriptors also move us some way to acknowledging the continuous nature of #geneticvariation across #humangroups in our sample descriptions. I am more genetically similar to some samples than I am to others, but that does not imply that there are natural groupings. Nor do similarity-based labels imply how I, as an individual, might choose to identify or what distribution of environments I might experience. For example, a person may be genetically similar to 1000 #Genomes samples labeled Southern Asian, yet in itself this similarity does not identify them as Southern Asian, whereas stating that a person has ‘Southern Asian #geneticancestry ’ comes much closer to making that linkage in people’s minds.
Working out the #genealogicalhistory of individuals and of groups of people from around the world is a fascinating area of research, but it should not be the day job of the majority of researchers in the field of #humangenetics , who instead need accurate sample descriptors of current day #geneticdiversity that aid clear communication.”
