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.

There are SO many "sensationalistic" sites, confusing "Goliath" of the Bible, denying the moon landing, etc. This man (from my university) is wonderful AND authentic. I always refer ppl to him.

Thank you all for this wonderful update to the National geographic show. I became fascinated with your work, and I am amazed at the speed of information that has become public. Again, thank you ALL!

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!

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.

UW rocks for posting these!

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.

Anyone else get claustrophobic looking at that cave-diving footage?

However, he only lectured partly in "Major Transitions in Evolution" with another professor. Both of these lecture series were excellent. Those are the only two that Hawks did with TTC. He must be too busy with his primary work. He has his own youtube channel with 25 videos.

Lots of Africa haven't been explored. But it is equally true that lots of Asia and Americas haven't been explored. A major part of human origin may be found in Asia and Americas too.

I agree. You can bet that the cave would be opened up very quickly if there were diamonds in there and it is entirely possible that it could be done without disturbing the dig site. I feel sure that the occupants don’t care anymore

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.

Good idea and a big maybe ...

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. Note: If the person who wrote the title did not pass the 6th grade, or is not a native English speaker, please accept my apologies.

Fascinating. Maybe they were hiding from something? Seems like they put themselves there. Also, maybe those chutes weren't so closed in back then. Maybe they were more accessible. Idk. I'm curious.

My Theory..Naledi would have regarded this cave as a treasure..they could hide from predators and larger hominids. They would have used this cave a lot and some would have died in the cave and their contemporaries would not be able to carry the bodies out so they would carry them down and try to stuff the bodies in the far corner to reduce the stench

@patb9375

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.

Professor Hawks is the spitting image of a Hollywood actor who has been in several movies recently. I can’t recall the guy’s name but the resemblance is uncanny

@craigfaber4777

It's a pun. The researcher who got stuck in that part of the cave is Lee Berger. So they nicknamed it the "Berger Box".

How did the bones get there in the first place?

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...

that's crazy. The area should've been subducted eons ago.

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!

Consider the reason these fossils were found in almost all reaches of the cave network without any evidence of habitation, Could it be that the cave network was a place of refuge from other hominids who were hunting them for food. 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.

Educated opinions lean STRONGLY towards the burial place, and have very good reasons for that.

I am thrilled about this discovery and everything it has to teach us about our past. But I have now watched multiple videos on this, and I am *astounded* by the total obliviousness of experts and laymen alike as they stand around gaping, scratching their heads, "it's such an impossible mystery, what kind of function could a place like this POSSIBLY serve? Why would hominids venture deep inside a cave, just to lay there, dead, out of reach of predators, so that their bodies are safe there while spending eternity below earth. IT MAKES NO SENSE! And they are all different ages too, I can't think of a single explanation for what could possibly be connecting these specimens! Except that they were carried there by the only creatures who were capable to get to it- maybe by their families or members of their tribe, if one were to speculate WILDLY ABOUT SUCH AN ENIGMA! If only there were known examples of other hominids doing something similar, like, ourselves! But I can't think of any. Hey, by the way, what do you think we should call this passage down into the underworld, guys? "Hades"? Aw that sounds cool! Greek mythology is coooool. O! o! I know, why don't we name all these chambers after what one of the most famous writers in human history called the chambers in his seminal work where a man stumbles upon a cave entrance that leads him descending on a journey through the Kingdom of the Dead! I can't for the life of me figure out what made me make *that* totally unrelated association. Yep, stumped on every level here. If I were to speculate just randomly, maybe these distant relatives of ours whose physiology strongly imply that they were expert climbers who likely climbed and spend most of their lives in close proximity to the only things there were around to be climbed back then --trees-- (just like WE used to do back in the days! What a completely random coincidence) decided to leave the safety of their lush canopy dwellings to kick around in the domain of every predator that would have had them on the menu, but then got scared, and in the confusion they ran INTO the ground, to the deepest possible point, and there they died of exhaustion and trembling fear after a baboon chased them down there and threw one of its teeth at them. I tell ya, folks, we have a MIND-BOGGLING CONUNDRUM HERE, no reasonable explanation for any of this. We may have to start to ask ourselves if this could be the work of aliens somehow, because when there is NO OTHER POSSIBLE CANDIDATE for an explanation, any koo-koo outlandish guess is as good as another!" Thanks for the video and the amazing find, but Jesus Fucking Christ...

I understand and appreciate the dangers of caving but at some point you have to say that the situation is too dangerous. Once you have discovered the cave chambers and given appropriate study, I would think you could open the passageway enough that people can get through safely without endangering themselves.
