    Poznik and Underhill have claimed haplogroup E, arose outside Africa

    "When calibrated with a mutation rate estimate of 0.76 × 10−9 mutations per base pair per year9, the time to the most recent common ancestor (TMRCA) of the tree is ~190 ky, but we consider the implications of alternative mutation rate estimates in the “Discussion” section. Of the clades resulting from the four deepest branching events, all but one are exclusive to Africa, and the TMRCA of all non-African lineages (i.e., the TMRCA of haplogroups DE and CF) is ~76 ky (Fig. 1, Supplementary Figs. 18 and 19, Supplementary Table 10, and Supplementary Note). We see a notable increase in the number of lineages outside Africa ~50–55 kya, perhaps reflecting the geographic expansion and differentiation of Eurasian populations as they settled the vast expanse of these continents. Consistent with previous proposals14, a parsimonious interpretation of the phylogeny is that the predominant African haplogroup, E, arose outside the continent. This model of geographic segregation within the CT clade requires just one continental haplogroup exchange (E to Africa), rather than three (D, C, and F out of Africa). Furthermore, the timing of this putative return to Africa—between the emergence of E and its differentiation within Africa by 58 kya—is consistent with proposals, based on non-Y data, of abundant gene flow between Africa and nearby regions of Asia 50–80 kya15".

    Lucknow: Ancient DNA lab at BSIP to unearth Harappan history

    Mohita Tewari | TNN | Updated: Sep 9, 2017, 10:18 IST

    ... Now, palaeo-scientists would be researching on the DNA of 20 skeletons procured from Rakhigarhi and Farmana in Harappa. The institute will officially declare setting up of the ancient DNA laboratory on its foundation day on September 10. The lab would also be the first in South Asia to study DNA of the prehistoric age. ...

    Judging by the text, they are only starting analysis. But I guess it's a different lab, not the one which should publish results in September(wait, it's already September).

    Multiple inputs Y-E, T, R? There seems to be little if any non-African input on the mt side.

    Here is something interesting on blood groups in ancient Europe.

    Jean M first brought it up in this post.

    Ancient steppe people had the highest frequencies of blood type A and of Rh- of the groups included in the study.

    No, I meant type A. Steppe peoples apparently introduced type B to Europe, but they had a higher frequency of A than the other groups and a higher frequency of Rh-, as well.

    DNA was analyzed from human remains found at the Antikythera shipwreck last year, but they are not yet published:

    https://www.theguardian.com/science/...ssical-statues
    Last year, the team found the skull, teeth, ribs and other bones of an individual who perished on the wreck. They have since extracted DNA from the skull and from it learned the individual’s sex and where they came from. Until those results are published, the person is known as Pamphilos after divers found the name, meaning “friend of all”, carved on a buried cup that had been decorated with an erotic scene.
    http://news.nationalgeographic.com/2...und-video-spd/

    Perhaps one of the most significant finds came during September of last year, when archaeologists found human remains at the site. It was the first opportunity to examine 2,000-year-old DNA from the wreck, which may provide more clues about its history. The DNA is still being analyzed but initial work suggests it was likely a young male.

    Inaugural Workshop Event: The Max Planck Harvard Research Center for the Archaeoscience of the Ancient Mediterranean (MHAAM).
    Date:
    Tuesday, October 10, 2017, 2:00pm to 6:00pm
    Location:
    Barker Center, Thompson Room, 12 Quincy Street, Cambridge, MA

    SoHp LogoMax Plank Logo

    Under the auspices of the Initiative for the Science of the Human Past at Harvard, and the Max Planck Institute for the Science of Human History in Jena, Germany, we are launching an exciting new virtual Research Center at Harvard and Jena: The Max Planck Harvard Research Center for the Archaeoscience of the Ancient Mediterranean (MHAAM). We are combining our institutions’ strengths in genetics, archaeology, history, and philology to bring the power of 21st-century technology to bear on some of history's great unsolved questions, starting with the peopling of the ancient Mediterranean, and the identity and impact of ancient pathogens on the fall of the Roman Empire.

    On Tuesday, October 10, Harvard will be hosting an inaugural workshop presenting some of the remarkable results of the initial research programs undertaken by MHAAM. We would be honored if you are able to join us for this unique event in Harvard Yard:

    2:00 pm – 5:00 pm: Public presentations of the first scientific results from MHAAM. Speakers will include Susan Alcock (University of Michigan), Johannes Krause (Max Planck Institute for the Science of Human History, Jena), Iosif Lazaridis, Michael McCormick, and David Reich (Harvard University). Barker Center: Thompson Room (12 Quincy Street, Cambridge, MA).

    5:00 pm – 6:00 pm: Reception

    "The Max Planck – Harvard Research Center for the Archaeoscience of the Ancient Mediterranean

    abbreviated MHAAM, is a research collaboration between the MPI for the Science of Human History in Jena and the Initiative for the Science of the Human Past at Harvard University in Cambridge (Mass.). Researchers from the participating institutes have agreed on a minimum duration of five years, until June 2021, to jointly examine the history of the Mediterranean area in the 2nd and 1st millennium BC. MHAAM provides common areas of action for scientists from archeology, history, and biology, by combining a multitude of methodological approaches for exploring the past

    The first settlers of the Mediterranean Sea used the unique natural landscape conditions that were created by the water as a bridge between the various regions to form extensive interaction networks. Intercultural encounters and exchanges, combined with extensive mobility of people, have characterized the development of the different cultures since then.

    DNA and isotope analyses on human skeletal remains are an effective tool to explore human mobility in the past. This mobility, in turn, formed the basis for the exchange of objects, knowledge and practices. A special emphasis of this project is on the investigation of bacterial DNA. Pathogens and human mobility in prehistoric times developed a significant dynamism, which could transform entire habitats and culminate in extensive movements of populations. From the intersection of isotope, DNA and pathogen analyses, with a well-founded historical and archaeological background, the researchers will be able to draw a dynamic picture of the past.

    At the core of MHAAM are three research areas:

    1. The first "globalization" of the eastern Mediterranean area in the late Bronze Age and early Iron Age (ca. 1600-1000 BC).
    2. The so-called "Phoenician" and "Greek" migrations in the early 1st millennium BC throughout the Mediterranean.
    3. The link between human mobility and the spread of diseases in ancient times.

    The interdisciplinary character of MHAAM is already evident in the make-up of the Center’s research teams. The Directors of the MHAAM are Prof. Johannes Krause, Director of the Department of Archaeogenetics at the Max Planck Institute for the Science of Human History in Jena, and Professor Michael McCormick, Professor in the Department of History at Harvard University and Chair of the Initiative for the Science of the Human Past. Prof. Philipp W. Stockhammer of LMU Munich, Institute for Prehistory and Early History Archeology and Provincial Roman Archeology, and Prof. David Reich of Harvard Medical School, Department of Genetics, are the co-directors of the Center."
