    Getting Neanderthal dna from cave dirt

    Would it be possible to get it from cremation ashes I wonder? Think of all the European ancient dna we could get for crucial periods.

    See:

    "Abstract

    Bones and teeth are important sources of Pleistocene hominin DNA, but are rarely recovered at archaeological sites. Mitochondrial DNA has been retrieved from cave sediments, but provides limited value for studying population relationships. We therefore developed methods for the enrichment and analysis of nuclear DNA from sediments, and applied them to cave deposits in western Europe and southern Siberia dated to between approximately 200,000 and 50,000 years ago. We detect a population replacement in northern Spain approximately 100,000 years ago, accompanied by a turnover of mitochondrial DNA. We also identify two radiation events in Neanderthal history during the early part of the Late Pleistocene. Our work lays the ground for studying the population history of ancient hominins from trace amounts of nuclear DNA in sediments."

    Do you have an idea, what the authors mean with "population replacement in northern Spain approximately 100,000 years ago"? The thing is, that 100 k ago, Homo sapiens didn't arrive in Europe yet.

    Real Expert: I read through a summary of the paper on Prof. Vernot's twitter post and he indicated the earlier Neanderthals were more similar to Altai and then over time the Neanderthals there became more similar to what is often referred to the as the More "Classic Neanderthals".

    Schöningen 300.000 years ago?
    Sima de los Huesos 400.000 years ago was not Neanderthal yet, but pretty close.

    Neandertahl findings older than 130.000 years are very rare, but afaik oldest Neanderthal findings are in Europe.
