Our Most Mysterious Extinct Cousins

[@stupendemysgeographicus5009]

These divergent branches of the human family tree are what I find most fascinating about human evolution. Modern great apes are known to copy human behaviours when in close proximity, I wonder if they did the same, and vice versa. Maybe the first individual to figure out how to make stone blades wasn’t one of our ancestors, but someone we copied.

[@Tziguene]

That rings true, on a deep level.

[@TheMaury101]

I mean aren’t the oldest known stone tools like 3 million years old? That might be exactly how we learned to make tools

[@stupendemysgeographicus5009]

@@TheMaury101 Indeed. Also, at least one population of chimpanzees has learned to use stone tools as well, though not to the same degree as our ancestors.

[@stupendemysgeographicus5009]

Also around 3 million years ago in Africa were giant relatives of modern sea otters, which use stone “hammers” to get into shellfish. If their extinct cousins did as well, then we might have picked up some ideas by watching them as well, though that’s highly speculative.

[@LimeyLassen]

I was taught in uni that the best way to avoid extinction is to occupy as much land as possible. This is even more important than genetic diversity, or adaptability. It's probability - the bigger the territory, the more likely some holdouts will survive any catastrophe, no matter how deadly it is. And that REALLY HAPPENED to Homo Sapiens during the Toba eruption, which almost wiped us out. I think about this when we talk about extinct hominid species. They might have been poorly adapted to changing world, but it's also possible that they just had a few bad dice rolls.

[@bbartky]

The first part of your argument is very interesting. Thanks for sharing it. However, I’ve read that that many anthropologists and paleontologists are skeptical about the Toba eruption bottleneck hypothesis. For example, they have found remains of human populations that were completely unaffected by the eruption. Here’s what I found on the BBC website: “In the past, it has been proposed that the so-called Toba event plunged the world into a volcanic winter, killing animal and plant life and squeezing our species to a few thousand individuals. “An Oxford University-led team examined ancient sediments in Lake Malawi for traces of this climate catastrophe. “It could find none.” My understanding is that most scientists reject it now.

[@LimeyLassen]

@@bbartky Thanks for the insight.

[@ckl9390]

Maybe that is why colonialism and expansionist tactics are so common amongst human societal groups. The need to take up space and spread out is baked into us because those who did so survived more often. This is also why I am not convinced by the arguments that climate change will cause the extinction of humanity. People point out how many current population centres may become uninhabitable, but those are not the ONLY population centres. And besides which, we have examples of areas like Doggerland where the environment did change and the area evolved from low plains to marshes to outright flooded. There are Dreamtime recollections of Aboriginal Australians describing the coastline of the landmass changing and significant portions becoming flooded withing a single lifetime. I think these usually line up with the end of one of the last ice ages. In such cases and the people who lived there were not destroyed, they adapted and moved. On a global scale, the worst of the projections may be problematic and knock us back a few centuries, but it won't lead to our extinction.

[@edwardadams9358]

A counter argument to the one presented in the video about human ancestors becoming generalists is embodied in the question "Why are there no bears in Africa?"

@@Snailz5 It's usually true, but it's not always true.

[@ThePauloVJCastilho]

If their diet was similar of that of gorillas, they would drink very little water, compared to other hominids. If your water needs are satisfied almost exclusively by your diet, and you eat things like roots, you are more likely to die of dehydration in a longer drought, since you would take longer to notice the changing environment and move.

[@Ezullof]

Gorillas are more adapted to jungle plants, which tends to be more nutritious, compared to the savanna plants that bosei was adapted to eat (big teeth and strong muscles) - even if their preferred food was apparently bulbs and roots. It's a rather peculiar specialization and it shows that they were already slowly adapting to a change in diet when they went extinct. So it's likely that they went through at least two adaptation events (with the second one being fatal).

[@stupendemysgeographicus5009]

Well, stone tools are what are specifically being talked about here. Considering all great apes use tools, all hominins must have used tools as well.

[@AlexandruBurda]

Differently from other animals and birds who make and use tools, we humans are developing and diversifying our tools. While other animals used and are using tools specifically and temporary, we humans were and are using them systematically. Simpler put, animals abandon their tools after use, we are keeping them and make them even better. 🙂

​@@AlexandruBurdaI've literally seen crows make different adjustments to wire to fit the job. Yeah, lots of animals don't keep tools, but it wasn't until relatively recently that our ancestors even did that. Tho there is some evidence that as far back as Australopithecus (Iirc) did leave tools where they were... Bc they had made a sort of factory with anvils for making the tools.

[@21katieus71]

that’s true, but we also have to think about what the tools might have been made out of. if hominids like paranthropus mainly ate softer plants as described in the video, they may not have had as much need for tools made out of stone. tools made up of wood or the like wouldn’t last long enough to be discovered by us today the way stone tools are. then there’s the fact that barely any evidence of that time period has managed to be preserved well enough for us to recover it, just thinking of the number of individuals who must have existed vs the few fossilized remains we’ve found. like our sample size of evidence is truly minuscule. 😭 it’s hard to draw any conclusions from it!

Most likely. I was watching something the other day about herpes evolution in the primate and human predecessors. There’s evidence to suggest it spread to one of our ancestors through the act of eating another member of a distinctly related lineage. Sure it could’ve potentially been through sexual contact, but it would’ve been more likely to get through an open wound. Ie fighting/hunting/butchering and getting infected blood in the wounds. Sexual contact would have to imply there was active sores and microtears or worse on the opposing side during the act. There’s also evidence we butchered and ate Neanderthals and vice versa, and we looked and acted VERY similarly-to the point mixed multi-generational family groups developed. You’ll eat anything when you’re hungry enough, and it would come down to physical vs intellectual advantages for who may have hunted who.

I was under the impression that a vital part of our ancestors’ evolutionary brain development was the incorporation of meat into their diets, because cognitive processes are so calorically expensive. If these hominids weren’t able (or willing) to branch out to meat, I feel like that possibly could have played a significant role in their inability to last.

Thank you science Daddy

I just sent a link for this video to Dr Jeff Meldrum at idaho State, who is one of the foremost foot specialists on bipedal of locomotion for primates in the Northwest; he's also cited on a lot of Bigfoot videos on KZbin.

Robustus! What big teeth you have!! “The better to eat you with, my dear.”

[@j3d1m1ndtr1ck5]

i have alway suspected that the reason for the 'uncanny valley' is because we competed with and feared other sapient species in our deep/lost past, and that they either died out naturally, or we eliminated them, but carry that instinctual fear of other sapients.

[@rmdodsonbills]

I get why you might not want to broach the subject in the main video, but is there any thought that those stone tools at the Paranthropus site might have been weapons that other Hominin's might have used against them?

[@andrewfleenor7459]

I think I've heard speculation to that effect from other sources. :-/

[@j.l.emerson592]

If paranthropus was killed, butchered & eaten by any other hominin, there would have been obvious marks of butchery on the fossils.

[@nickrider5220]

Our catalogue of wars would indicate we are a dangerous species, we fight each other...what do you think happened ! We are bright, but most of all we are war like.

[@CosmicSomnia]

Maybe the question we really should be asking ourselves is not why ours numerous relatives are extinct, but why we aren't? Perhaps the hominids were a dead-end species, one that shouldn't have survived (meaning: the direction of our evolution relied upon specific conditions that ceased soon before the extinction of our relatives), but homo sapiens evolved something unique and ground breaking enough to escape the extinction of the hominids? Food for thought.

[@aninewforest]

Homo sapiens is a super-predator. Our uniqueness is mostly how talented we are at various forms of violence :(

Here’s a cool idea for a future video, exploring the Artifacts of ancient Europeans during the Wurm glaciation, like the fertility goddess’s or the mammoth tents

The artist's rendering of the male with the ken doll bump instead of genetalia has me wondering (and laughing at) what his junk actually looked like. ..further proof that boys don't grow up, we just get bigger, lol.

[@ZedaZ80]

Plot twist: it was a remarkably deep convergent evolution and was actually a reptile, not a mammal.

[@Min-ke6zc]

If our fellow apes are any indication, probably remarkably small by our standards!

I second that! 🍻 🗣️

[@Warg666]

The BIGGEST change that we had from the Primate to Human evolution was 1 KEY step that took our brains to a whole different way of learning, eating cooked meat, as cooked meat brings out the proteins better for us to digest and the bodies evolved from that as did we!~

[@alexgee3762]

Awesome video! Is there a possibility that the tools found with Paranthropus be from another hominid species (such as ancestral Neanderthals) consuming Paranthropus?

[@iqop]

This was my question, as well!

[@vinny184]

there have been tools found in multiple locations with Paranthropus remains, some without any other hominid remains. By that time our lineage hadn’t yet diverged from Neanderthals.

[@Ezullof]

Neanderthals are completely impossible because they evolved in Europe around 450k years ago, while P. bosei is from 2.4 to 1.2 millions years ago and only found in the southern parts of Africa. But yes, it's been hypothesized that the stone tools were made by H. erectus. The thing however is that lithic technology is dated to 3.3 millions years ago anyway (with Kenyanthropus, and before the first Homo) so there's no reason to assume that Paranthropus couldn't do it. In fact it wouldn't be too surprising to discover that the only reason why modern apes don't also have a proper lithic industry is simply because they don't need it.

[@alexgee3762]

@@Ezullof thanks!!

[@saltenzy449]

I feel like everyone asking the "what if X went differently" questions should really take on speculative evolution as a hobby. Lots of projects already in the works exploring potential evolutionary paths for earth life, which are fun to read as well as contribute to.

[@mikebauer6917]

I would imagine extinction is the default path for a species.

[@davidt3563]

Love this show!

[@tweak_squeak]

Coz should’ve gone intelligence/dex build like us instead of strength/construction maybe he’d be alive still

[@zackakai5173]

Honestly with how dumb some members of *our* species are, I wish our direct ancestors had specced a bit *more* into intelligence than they did.

[@Raven5150]

Somewhere in our history the Congo River flooding sepperated a common ancestor thus making different food sources

Yeah, I'd rather eat C3 than C4...
