Whatever Happened to Homo erectus? - Science Talk

Who’s your (ancient) daddy? Did he walk upright? Could he control fire? Did he have a brow ridge that wouldn’t quit?! Then maybe he was a Homo of the erectus - not so sapient - type. Many new Homo erectus specimens have been added to the global repository in the past decades, and many new interpretations have followed. It is more that most can easily digest. Come join professor Henry Gilbert, discoverer of the Daka Homo erectus cranium, to have the Pleistocene evidence of your ancestors’ evolutionary history explained.

Really good talk! I like his use of scientific reasoning and usage of data. I find homo erectus more fascinating than Neanderthals because they traveled so much of the world. It's strange that a world wide species could have died out, everywhere. What did happen to them?

[@swyman10]

Tragoudistros.MPH I don’t believe they died out...I believe they are in us today, that we have in a convoluted way, inherited their genes. They live in us.

[@oldwoman2121]

@@swyman10 I so agree. It's comparable to hearing about the same issue--extinction--regarding more recent groups of people; for instance, Mayans didn't "disappear" and Aztecs didn't "disappear"--they simply coalesced with other groups of people... and now they're called "Meso-Americans" or, more narrowly (for instance) "Mexicans". I agreed with the speaker, as well--there's too much "over-splitting". Hair-splitting when it comes to race and ethnicity.... if you will.

[@mindalacy]

Multiple species living at the same time, even closely related ones, should be something important to consider rather than assuming that variation in one species accounts for all the differences in related looking fossils founds. This competition for resources between closely related species is what creates the selective pressure for advantages like the encephalization, frontal lobe abstraction and language skill; the ones that drove our species separation. Without the competition, which could just be environmental changes that create more stress on some but less on the advantaged, not necessarily direct competition or something as dramatic as warfare, there would be little else to drive the changes.

[@rlbadger1698]

+Minda Lacy I think more likely, isolation and line breeding created a multitude of sub species. Your trying to fit a world view (modern) into a frame work of extremely low populations. Remember that at multiple points in the last million or so years the hominid populations where as low as 60k worldwide. On average maybe 500k hominids worldwide.

Minda Lacy I don’t accept the idea of competition within a species driving separation into new species. Adaptation is driven more by weather (ice ages, savannah, altitude) and diet - more protein creates bigger brains. Hitler believed in “struggle” within species which underlay his racism.

A small contribution: At 44.15 appears "Kocabash" fossil from Turkey. He almost had the correct pronounciation except that "c" in Turkish gives the sound "j" as in English words (i.e. joy, Joshua, justice etc). The pronounciation should be koja-bash, which means "koja"=big, large, and "bash"=head in Turkish. Many thanks...

Great talk. problems: The very earliest tool makers there were moving good rock at least 10 miles when the local rock was crap so five miles isn't likely to be the limit for He. The trouble with bifaced/acheulean tools is that many of them have deliberately dulled edges which knappers do to be able to control fracture better. The conclusion by one knipper is that most bifaces was pretty much being used as a core from which the maximum amount of sharp chips were removed. At Boxgroove England they thought hand axes were being made by design but they were also commonly being broken up to get more edge. Edges were studies on very early stone tools show they were used to cut plants such as tubers, wood, and process animals. He, Homo erectus, surely did at least that much.

Henry, A mistake by the Prof, who I agree gave a good overall talk. He says brain size and IQ don't relate. Lots of articles and sites agree with the Prof that brain size and IQ don't relate. That's the PC view of IQ. That view of IQ is heavily skewed by PC, which is like a wet blanket on University thought. That's why I offer this evidence that the interesting speech is wrong on brain size and IQ. From: www.news-medical.net/news/2005/06/19/11121.aspx - here's the title and a few para's: People with bigger brains are smarter than their smaller-brained counterparts, according to a study conducted by a Virginia Commonwealth University researcher published in the journal "Intelligence." The study could settle a long-standing scientific debate about the relationship between brain size and intelligence. Ever since German anatomist and physiologist Frederick Tiedmann wrote in 1836 that there exists "an indisputable connection between the size of the brain and the mental energy displayed by the individual man," scientists have been searching for biological evidence to prove his claim. "For all age and sex groups, it is now very clear that brain volume and intelligence are related," said lead researcher Michael A. McDaniel, Ph.D., an industrial and organizational psychologist who specializes in the study of intelligence and other predictors of job performance. The study is the most comprehensive of its kind, drawing conclusions from 26 previous - mostly recent - international studies involving brain volume and intelligence. It was only five years ago, with the increased use of MRI-based brain assessments, that more data relating to brain volume and intelligence became available.

This the old interpretation of how Homo erectus lived (running-hunting etc.), the information is excellent, but the interpretation is unfortunately biologically outdated.

[@zliu4208]

Philip Thomas Some recent genome study has found that the genome of several modern Western African populations have traces of archaic hominin, namely “ghost populations”, genomes, ranging from 2-19%. These “ghost populations” would have played a similar role to the modern subsaharan African population as Neanderthals and Denisovans would have played to modern populations outside of Africa in terms of genetic contributions. However, I wouldn’t use the term “broader” as the range wasn’t established with the genome of any archaic hominin fossil specimen as the reference. No specimen of such “ghost populations” has been identified because the warmer climate of Western Africa isn’t ideal for fossil formation. In addition, as the originating continent of the Genus Homo, prehistoric Africa would presumably have a higher degree of diversities in terms of speciations within the Genus Homo. Therefore, we might never be able to positively identify a hominin fossil specimen as that of the said “ghost populations”. The link to one of these study is attached below: advances.sciencemag.org/content/6/7/eaax5097 We are all different “hybrids” between predominantly ancient Homo Sapiens, originating in African continent, and other archaic species among the Genus Homo depending on the geographical locations. It is disheartening to see a small number of African Americans taking up such an Eugenic way of approaching anthropology as it had been used to denigrate them in 19th and early 20th century. We as a society, should always be cautious of any political rhetoric that attempts to claim to be the “ultimate truth based on science” as its justification.

27:00 - While I don't personally have any approval whatsoever for the Piltdown perpetrator's actions, I think the gentleman makes a fair point. At least he's "identifying a positive aspect of the outcome," so it becomes a rational question to ask. Dr. Gilbert made some great points in his reply too. Ultimately I think that if someone wants to hold the opinion that there were some positive aspects of Piltdown, I can respect their position. I don't share that position - I just attach too much value to integrity in science. But I think the question is fair. Piltdown shouldn't have been done. But if every single effect it had wasn't bad? Well, GOOD. That's better than them all having been bad.

There didn't have to be a time when the early sapiens survived the late erectines through some great cull. Small changes happened slowly, every combat event between very similar males winning the females. There is the culling: one small 'war' at a time, spreading genes in ever increasing radii. Think a male grey-ferel cat variant spreading to only one new neighborhood (of striped tabby) and winning there; then his chip-off-block variant spreads to one new neighborhood from there and is victorious; and so on and so on with slow changing of the population's morphology. When we look at BIG PICTURE changes in the geologic record we are seeing, along with the process above, a grand selection through intense NEW selection pressures (enviros can change like straws on a camel's back). That situation allowed only one odd variation of each clade to survive; i.e one otherwise "weird" outlier species-variant of a genus, family, order, etc was the lone survivor. That survivor then became the "basal form" of the next diversification (genus, family, order, etc) into that new geo /enviro Era or Period. Imagine a scenario where enviro changed and all mammal metabolisms couldn't survive it except for sloths (with the thick slow blood). Sloths would now be the basal STEM strain that diversified into that new environment Era or Period. Then the processes above continue.

[@KipIngram]

8:00 - I think during any time of a "new theory" there will be people who want to question it. In this case there was the added overtones from religion and so on, but I'm talking here about *scientists* who are earnestly trying to "be scientific," not people with an agenda to push. For one thing, what's better for you as a scientist? To climb on board someone else's theory? Or to advance a theory of your own that proves to be correct? Obviously, it's the latter. So there's always a tendency to want to promote an "alternate idea." Sometimes theories get to be so well accepted that it's actually dangerous to oppose it, and I think that's the *current* state of natural selection - it's just really hard to justify any doubt, so you don't see much opposition to it among serious scientists. But when a theory is new, the "risk" of questioning it is a lot lower, so I think you almost always see people doing just that. I think this is *healthy* - it's good to have varied ideas on the table getting taken seriously by competent scientists. Because once in a rare while, one of these alternate ideas is *right*, and after a while we figure that out and it displaces the other idea. Dogmatism is as bad in science as it is anywhere else. There are a lot of scientific thinkers in the world, so we can afford to have a few going on wild goose chases. Once in a while we benefit from it. Being "too quick to dogmatize" is a very dangerous thing. A great example, in my opinion, is Lamarck. He proposed radically different ideas from Darwin. After a while, he was basically branded a heretic. But look at us now - now we're talking about epigenetics, and in some cases the effects of epigenetics look an awful lot like what Lamarck was talking about. It's not, or not exactly, at least - he was, in fact, wrong. But at the same time there was "something there" that was worth discovering, and I think one of the reasons it took us so long to find it was because Lamarck's ideas were "cast out." It became positively dangerous to be anywhere near those ideas, and so it took us a hundred years to really recognize epigenetics. Don't get me wrong - I'm not endorsing "just any crackpot idea." I have as little use for flat earthers as anyone else. Sometimes the ideas people push forward are *so far* out of bounds that they just can't be taken seriously. But I do think we are sometimes too quick to reject ideas. Honestly, as long as a scientist is actually trying to "be scientific" in their thinking and their methods, I'm fairly content to let them. Most of the time they'll just ultimately prove themselves wrong. But it's not wrong to look at possibilities.

I find idea that we lost our hair at the end of the ice age unconvincing. After all, other primates retained their hair. According the NY Times article, there is genetic evident that we lost our fur well over a million years ago while the last ice age continued to about 10K years ago. The NY Times article offers some fascinating theories, though. One that strikes me as probable has to do with reducing the effect of parasites, particularly as we moved out of Africa and into other ecological zones. The idea that we may have gone through an aquatic phase may have merit but there doesn't seem to be any convincing evidence for it. Thanks for the responses.

It seems to me that this field of science could learn from the microbiologists when it comes to naming things. Among bacteria, for example, there are thousands of intermediate species and we constantly turn up bacteria that don't fit cleanly into one species or another. If one performs an API test, which measures the ability of a particular organism to utilise particular substrates, then looks up the API data base to see where a particular bacterium fits, it says things like 65% chance that it is an E. coli and 30% chance that it is a Citrobacter freundii, etc. In humans, all the intermediates have died out but in microbiology we deal with them all the time because they still exist. Maybe these scientists need to adopt a similar approach because hominin species have varied constantly and flowed into new types. Bacteria pass genes between them just as branches of the human tree have, so why not classify specimens as 65% chance of being Homo erectus etc., based on measurable parameters.

There isn't one because evolutionist scientists can't find any transitions from one kind to another kind. ape like sculls and using gene flow ,DNA is not viable evedence .but if they can show me through a scientific process one kind changing in to another kind then u think again about evolution.

There was once a concept of "The Missing Link". The governments and churches derided this concept, along with ridiculing Darwin's theses. Now there are at least 30 missing links that are not missing at all.

As muscles are used more they get larger and the bones they are attached to get larger. Surely it follows that a brain that is used more grows and requires a greater cranium to house it. Humans did not suddenly become sapient it was a slow and long development each new experience leading to more brain usage and increased intelligence. Our ancestors were not ignorant there brains were just a little less developed. Surely it was not increased cranium capacity that led to larger brains but rather increased brain usage that required increased cranium capacity.

There are different races and lots of variation within Homo sapiens. This was probably true of Homo Erectus. I tune pianos so whatever that's worth.

[@edwigcarol4888]

What is a race ? Modern genetic studies have shown that there is no race on earth today aming homo sapiens. Means: There might be high similarities genetically between say an asian individual and an african one, while two neighbors of the same region (over 100 years. Mean no immigration) present a larger difference than the two people of asia and africa mentioned above. Genetical variation aming homo on earth today does not correlate with the morphological body shape that different population present. What we see between world regions is a morphologic adaptation as a response to temperature and others environmental influences. And this is real expert stuff to understand how it works. Means expression or methylation of the same set of genes. Has been definitely a very important inquiry.

[@Geoplanetjane]

Race is nothing more than a political construct, made to differentiate on minor physical characteristics in order to prove that white people were superior to people with different outward appearances. Ultimately this was solidified into dogma to justify chattel slavery, because the dogma was that the supposed African and Asian races and those categorized as Indians, American and otherwise and Australian aboriginals have all been categorized as less than human in order to justify slavery and other forms of oppression. Genocide, even. So, race is a political myth.
