The diaspora of modern humans across Eurasia — update and revision

❝ Most people are now familiar with the traditional “Out of Africa” model: modern humans evolved in Africa and then dispersed across Asia and reached Australia in a single wave about 60,000 years ago. However, technological advances in DNA analysis and other fossil identification techniques, as well as an emphasis on multidisciplinary research, are revising this story. Recent discoveries show that humans left Africa multiple times prior to 60,000 years ago, and that they interbred with other hominins in many locations across Eurasia.

A review of recent research on dispersals by early modern humans from Africa to Asia by researchers from the Max Planck Institute for the Science of Human History and the University of Hawai’i at Manoa confirms that the traditional view of a single dispersal of anatomically modern humans out of Africa around 60,000 years ago can no longer be seen as the full story. The analysis, published in the journal Science, reviews the plethora of new discoveries being reported from Asia over the past decade, which were made possible by technological advances and interdisciplinary collaborations, and shows that Homo sapiens reached distant parts of the Asian continent, as well as Near Oceania, much earlier than previously thought. Additionally, evidence that modern humans interbred with other hominins already present in Asia, such as Neanderthals and Denisovans, complicates the evolutionary history of our species.

The Max Planck Institute is the gold standard for research into the evolutionary biology of homo sapiens. When original discussions stretched around the world at the turn of the 21st Century, debate and discussion took over a great deal of public and non-institutional dialogue on the latest discussions of evolution. Scuence readers and writers as well as core researchers were all involved.

I spent about 2 years getting my head around the results of the first DNA analysis providing deeper genetic and chronological analysis previously impossible. While spirited debate was often the order of the day – well above the perpetual attempts to educate superstitious folk stuck into biblical fiction – I have rarely so enjoyed the weekly expansion of knowledge rolling out the doors of the Max Planck Institute like tides changing the face of the intellectual Earth after an Ice Age.

Oh, yeah. Between 3 and 4% of my overall DNA is Neanderthal. Never was one of those straight-up white guys. 🙂

    “Very old, very sophisticated tools found in India. The question is: Who made them?” (Washington Post) https://www.washingtonpost.com/news/speaking-of-science/wp/2018/02/01/very-old-very-sophisticated-tools-found-in-india-the-question-is-who-made-them/ “In a paper published Wednesday in the journal Nature, researchers described thousands of stone implements uncovered at Attirampakkam, an archaeological site in southern India. The tools span about a million years of history, they say, and illustrate the evolution of big, blunt hand axes into finely sculpted stone points. Starting about 385,000 years ago — long before modern humans are thought to have arrived in India — it appears that an advanced toolmaking culture was developing there.”
