Second Cave Chamber Reveals Spectacular New Homo Naledi Skull and More

The first fossils of Homo naledi, discovered in 2013 and described as a new species of hominin in 2015, have just been dated to coming from only 236,000 to 335,000 years ago—close to the origins of our own species. (Read: Did This Mysterious Ape-Human Once Live Alongside Our Ancestors?)

What does it mean for prevailing models of the human family tree? And what about the contentious idea that they intentionally disposed of their dead deep in caves?

New papers published today in ELife by National Geographic Explorer-in-Residence Lee Berger and team shed new light on this mysterious member of our family. They also reveal that a second chamber contains the remains of at least three more individuals, including the most complete Homo naledi skull yet found (seen above).

Dig in to the discovery for yourself with the open-access papers, complete with photos of the fossils, cave diagrams, and more detailed information to sink your own perfectly adapted teeth into:

    Is it possible that the caves represent an early primal settlement; not necessarily one by design but a spontaneous occurrence for various subsistence advantages.
    Does disposing of bodies represent primal spiritualism? Is spiritualism a survival strategy? Is it hard wired… something that allows us to cope with the unknown; an embedded system that allows us to believe we will be safe as we move forward over the next mountain, up the Danube and into western Europe? My apologies if these questions are beyond scientific purview but Göbekli Tepe suggest that spiritualism was practiced while we were only mobile. It is easy enough to come up with examples of spiritual practice. Defining or understanding what it actually is has always been elusive.

    So these folks likely witnessed the creation of the Tswaing crater some 50km north west of the cave. Wonder if the males are Haplogroup A?

    Sorry, I meant to say “… Tswaing crater some 50km north east of the cave.” Anyway, that meteor was large enough that a layer of dust was perhaps left in the cave!

    Naledi is a fantastic find, but there’s nothing human in it: all its humanlike traits are primitive for Homo & Pan, e.g. prenatal chimps have humanlike feet which near birth become handlike (C.Coon).
    There was no deliberate burial: naledi fossilised naturally: they lived in swamp forests, wading bipedally in forest swamps (flat feet as in wading & swimming birds & mammals, not adapted to fast running) & climbing vertically in the branches above (curved hand-bones).
    Google e.g. “Pan naledi 2017” & “bonobo wading”.
