There is zero chance our nearest common ancestor was only 3000 years ago.

  Feel free to post scientific papers that show this.

    A moment's logical thinking demonstrates it. "Scientific papers" are not the currency of correctness.

      And yet they are worth infinitely more than simple contradiction free of any evidence whatsoever. A moment's though yet you can't write it down?

  I wonder if the authors of the paper thought about that issue. How is "nearest common ancestor" defined?
  • zamadatix 2y ago
    The paper uses the proper term "most recent common ancestor" (commonly abbreviated MRCA) which specifically means the most recent individual from which all individuals of a set (such as "all humans") are genetically descended from (i.e. if you traced everyone's lineage at least one branch up the tree would always hit this person, not that this person was the only source of genetic information from that time).

      Clarity: it should have read "if you traced everyone's lineage _then_ at least one branch _somewhere_ up the tree would...". I realized the way it was written could be ambiguously read as "if you traced everyone's lineage _by_ one branch up" after the edit window had passed.
