  • (10/04/2017) John Hawks, UW-Madison Anthropology. The Rising Star cave system in South Africa contains the largest known assemblage of fossil human relatives ever found in Africa, all belonging to a previously unknown species, Homo naledi. Earlier this year, the Rising Star research team revealed that these fossils may be as recent as 236,000 years old, meaning that this primitive extinct species existed around the same time as the origin of modern humans. The team also announced the discovery of a second bone chamber with more remains of H. naledi - including a nearly complete skeleton they named Neo. Professor Hawks will discuss how these findings change our view of human evolution. He is returning from the excavation in September and will give the first report of this new work.

    Always a pleasure to view a lecture from Professor Hawks! The content is very interesting - but if I had one comment to make is I highly agree with the position that discoveries should be in public venue. I think the sharing that's been the cornerstone of the Naledi Cave discoveries has been so broadly public from the beginning is really the right direction. My hat is off to those scientists who set that direction, the South African government for forcefully supporting it, and everyone else who's helped set that course.

    I really enjoyed this lecture. I love hearing about Homo Naledi & the team that is working to discover, recover, analyze & present the findings to the public. I hope Nova is planning to do a sequel to Dawn Of Humanity. This discovery, the personalities behind it & the story it tells is one of my most favorite things. I am grateful I didn’t have to wait 10 years to learn about it or come up on a pay wall. Hooray for open science! Hooray for John Hawks!

    I'm back a year later. The attitude of keeping all the info under wraps is so dumb. By sharing the finds with as many experts as possible, more work gets done quicker. Letting students have access will inspire more applicants for anthropology, biology, geology, paleoanthropology. Current students in those fields will have more material to do their own theses. It's a win win.

  • @zioo3117

    Presumably (never assume?) these various anecdotes of how narrow the access in these caves were found to be by the team, provides me with a presumptive conclusion, that over time, epochs of time, even, such difficulty has allowed the current professionals to access the caves, while amateur spelunkers over the centuries, thousands and millions of years had such a hard time getting in, that they were unable to remove or otherwise disturb the finds. This is rather a contrast from some other sites in the world, such as in the Valley of the Kings and other areas that had been purloined repeatedly over time. Like some "barn find" cars, they are only original once. A different non-comparable aspect of life and production, but the idea is that there is a fiarly good confidence that the Naledi were discovered undisturbed since they were ensconced in their "find" location. How many human types tried to get into these cave over the millenia is unknown, but not finding "stuck" humans inside from different millenia or times frames, is exciting from the point of view of someone finding something, "for the first time." It is sort of like, that in fact, it was "for the first time." Dating the fossils is then the most important thing that can be done other than investigating just what these living beings actually were.

      They have not found signs anything lived in the room called Dragons tail. They are searching for soot etc they think the one dragging them in had to use something. They where dead when pushed through the chute, the bones where piled up under the chute. That is why the rib section is mostly missing. They laid under the chute and gassed up from intestine, etc. then this destroys the bones that are close. So they have hands, feet, leg bones, etc.

    A community group of Naledi were using the cave. Perhaps merely as safe refuge in bad weather. Maybe a cool place to hang out during very HOT days. The rock fall that researchers climb up to get to the chute entrance was not always there. It fell from the ceiling above. That back cave was not always blocked by the rock fall. One possibility is that the cave in happened when a group was back in that cave, trapping them there. Some likely would have been killed by the falling rocks, and their bones may still exist UNDER the rock fall. The survivors all would eventually succumb to co2 poisoning. Dropping where they were. Those in the back crevices desperately seeking exit. Most in the open center where the majority of bones have been found. That cave was not always so hard to access. Fact. Did the cave in happen timely to when Naledi were in the cave? Possibly.

    That title... I'm startled to see that it is possible to "...CHANGE human origins" (emphasis added). Wow!
    Wouldn't that require time travel? Among the other challenges that changing something like human origins would entail...
    Or, did they mean to say that new discoveries of this hominid species (for several reasons, I prefer this time-honored term) is changing OUR IDEAS ABOUT human origins? Or, these discoveries are changing the way we view human origins? The title could have continued to the next line.
    Does it matter? Since language is one of the defining characteristics of humans, and the purpose of language is to facilitate clarity and detail in communication, it seems obvious that it is important to say what we mean.
    It could have read: 'Homo naledi: Discoveries Shed New Light on Human Origins',
    among many other possibilities that would have said what the lecture was really about - rather than changing something that occurred in the distant past, which is, so far as we know, is impossible.

Better to squeeze into the remotest reaches of the cave and die there than to come out and be slaughtered and eaten by your pursuers. Just a thought, but I guess we will never really know for sure.

    • @patb9375
      @patb9375 5 лет назад

      Not lost they are dead, they are searching for soot etc they think the one dragging them in had to use something. They where dead when pushed through the chute, the bones where piled up under the chute. That is why the rib section is mostly missing. They laid under the chute and gassed up from intestine, etc. then this destroys the bones that are close. So they have hands, feet, leg bones, etc.

    My best guess (imagining, dreaming) is:
    as they lived 600.000 - 250.000 ago, being less evolved than hominins farther north, they could have faced the invasion of these hominins species from the north, which were mightier, cleverer, better organised ..
    Terrified they flew and hid in theses caves. The fear pushed them into the narrow passages. As the enemies waited outside, they didn't dare get out and starved...

      I (educated) guess that there will be much more biology info released in the next year or two. In particular, there are easily enough teeth and they are fresh enough that DNA will be recoverable from many individuals. I agree with you, that it'll be fascinating to learn about their biology.
      On the other hand, it's pretty obvious that Naledi is very much an offshoot from our line (and vice versa), so any biological sharing will date back to a branch point about 2 million years ago. Although talking about "branch points" is looking less and less realistic these days, as it appears that there were many concurrent hominin species that likely cross-breed with each other to some extent.

    I feel for the excavators, if that's the term, and how very difficult it is for them to crawl to their sites. Is it possible, and of course only very carefully, of safely streamlining some of the extreme areas? I think of the man who became stuck in there, the worst scenario. Also I'm concerned about their not progressively making their way into each space. Wouldn't their weight on the sediments effect what is to be excavated in the future as they are going to and fro over areas that have not been excavated yet. Like first excavate the area where all their headquarters is, then gradually progress into the cave. Also, futuristically, I'm wondering if tiny particles are being tossed out. If they find a site with all the teeth present and the rest of the "fossil" (wondering why they don't say "bones" yet maybe they are quasi-fossils) or bones are "gone" if some day a very sophisticated software program or quantum computing perspective could analyze particles of bone and actually in 3D reconstruct like a skull that otherwise would be unseen by our own eyes. For this reason I wonder if they might leave some areas of the chambers for future generations. Are there any experts who know? I wonder why he didn't make sure everyone knows were to go on the internet to access their website and be able to ask questions. Thanks for presenting this great lecture!

      Greeny202a It is a matter of mass ratio. The whale brain is huge but so is the body it must control the function of. A smaller brain size is not a direct indicator of intelligence. It must be taken in context with the body it is in charge of.

    I'm still stuck on several points in this mystery and would like to offer the following: Perhaps the people left in the cave were prisoners or sick people having some disease believed to be infecting others in the tribe and the leaders decided that they must be quarantined. Or perhaps they were forced to go into the cave as punishment because of some infraction of tribal law. Still, why not simply kill these criminals on the surface and bury them there and be done with it. Or in either case, if they were dead when placed in the cave then the people on the surface had to 'speak or communicate' in some fashion in order to give even rudimentary directions to those who's duty it was to be get the bodies into the cave in the first place. Such a complicated task as this could not even be attempted (even in daylight) without talking to one another or drawing plans on a flat rock with a piece of charcoal, or pantomiming some sort of weird skit or play that would explain what needed to be done and why. No one would be able to complete a confusing job like pushing and pulling dead bodies up and down a narrow cave tunnel unless one of them (say the leader? or the strongest member of the tribe?) simply took it on himself to one day suddenly start pointing and grunting and trying to explain the job that was at hand or that he wanted the other to do and why. No, these people had to talk'. Also, what about the smell? Fifteen bodies in a small room of a cave with little or no air circulation, even if they were put there one at a time over say a years period would certainly begin to smell. What member of the tribe (and it would take at a minimum of two people and several lengths of rope to get even one dead body into the cave room where it was to remain). And who would voluntarily say, "I'll take the bodies into the cave. Let me do it."? This would unquestionably be a place where the smell of rotting corpses would overwhelm even the most ardent servant of the tribe. Who would say he or she wanted to do the filthy job? Also, the members of the tribe who's responsibility it would be to take the dead bodies into the cave or force living people (as prisoners or for some other reason) into the cave (or who knows? perhaps they went willingly for some strange reason), into the total darkness of a cave where the openings and passageways are so narrow that no normal man or woman could get through himself, let alone pull or push or force a dead body or a live person in without giving directions and listening to the other fellow who was helping him explain what had to be done when they had to move past a narrow spot along the way would be impossible. And then there is the problem of light: it would be almost impossible to use nothing more than the brail method to even find the cave room deep underground where the bodies were to be taken, let alone get a body delivered to the room. Who among you would not say to his helper half way down into the cave, "Hell, this is good enough. let's just leave him here. The boss is too old and too fat to come even this far to check on where we put them."
