• Recent erectus find establishes earlier appearance

    Recent erectus find north of Johannesburg in South
    Africa, and well inland...

    Contemporaneity of Australopithecus, Paranthropus,
    and early Homo erectus in South Africa

    "The DNH 134 cranium shares clear affinities with
    Homo erectus, whereas the DNH 152 cranium represents
    P. robustus. Stratigraphic analysis of the Drimolen
    Main Quarry deposits indicates that unlike many
    other South African sites, there was only one major
    phase of relatively short deposition between ~2.04
    million years ago and ~1.95 million years ago. ...
    The DNH 134 cranium shares affinities with H.
    erectus and predates all known specimens in that
    species."

    "The DNH 134 Homo cranium has affinities with H.
    erectus and extends the species’ temporal range
    by ~200,000 to 150,000 years. DNH 134 being older
    than A. sediba complicates the likelihood of this
    species being ancestral to Homo in South Africa,
    as previously suggested. With the oldest occurrence
    of H. erectus at the southern tip of Africa, this
    argues against a suggested Asian origin for H.
    erectus."

    "We interpret the occurrence of Homo aff. erectus
    at this time in South Africa, and soon after at
    Dmanisi (73), as evidence for a major range
    expansion of this species (covering at least 8000
    km) both out of and within Africa around 2.0 to
    1.8 Ma ago."


    And from the study on the green Sahara pathway:

    https://www.nature.com/articles/s43247-023-01034-7
    Low-frequency orbital variations controlled
    climatic and environmental cycles, amplitudes,
    and trends in northeast Africa during the
    Plio-Pleistocene

    "We find that there were many periods of more woody
    Green Sahara intervals, including a particularly
    woody vegetation (over 50% C3) interval at ~2.2 Ma
    in the Nile River catchment (Fig. 2a), generally
    coinciding with the first dispersal out of Africa. A
    large, vegetated area connecting east and northern
    Africa may have triggered a pull-type response in
    hominins that were now able to survive using larger
    cranial capacity79 and move in the lush, ecologically
    connected, region of northeastern Africa."

    AND THEN A STUDENT decided that it was closest to erectus. Which is

    That's just shy of two years old.

    Yes, most likely it was a male Au.robustus cf.
    - its cranial capacity (larger than in female robustus, but only half as large as in erectus),
    - no pachyosteosclerosis >< H.erectus:
    only kudu runners think it was their ancestor... :-D

    "DNH 134 is strikingly similar to the Mojokerto H. erectus cranium in
    overall cranial shape (Fig.4)"

    https://www.science.org/doi/10.1126/science.aaw7293#F4

    What's the logic here?
    Well, if Mojokerto is H. erectus and DNH 134 is strikingly similar in
    overall cranial shape then DNH 134 is most likely also H. erectus.
