    Hi David,

    thank you for this indication! I found the following:

    Adcock G.J., Dennis E.S., Easteal S., Huttley G.A., Jermiin L.S.,
    Peacock W.J., Thorne A. Mitochondrial DNA sequences in ancient
    Australians: implications for modern human origins. Proceedings of the
    National Academy of Sciences USA 98 (2001), 537-542.

    Is this the paper you have in mind? Or was that something else?

    Adcock et al. come to the conclusion that the mitochondrial DNA which
    they analysed (from the 62,000 years old gracile Australian LM3
    skeleton) forms a clade with the mitochondrial insert on human
    chromosome 11, and that this clade diverged an unknown time ago from the
    progenitor of the most recent common ancestor of all living humans.
    However, the Neandertal DNA clade branched off even earlier. Their gene
    tree uses chimpanzee and bonobo mtDNA as outgroup, but says nothing
    about an ape homolog of the insert. As the mtDNA is under selective
    pressure, these findings are not quite what I was looking for.

    For the insert, they refer to Zischler H., Geiset H., Von Haeseler A.,
    Pääbo S. & Geisert H. (1995), Nature 378, 489-492, which is quite a bit
    earlier than you indicate. I haven't looked it up as yet.

    Peter
