There are people on CZcams who are not nearly as talented as Lindsay is at conveying this kind of information. She ought to have her own channel and if she needs any encouragement she has it from me. I think a lot of other folks would support her as well.
Chris Stringer and other leading anthropologists cite evidence that Homo Erectus may have been in Java as late as 70K years ago. It would be interesting to compare the skull structure of the earliest (almost 2M years ago) and the last of the Homo Erectus, if they became more modern looking.
more hope with the expanding field of genetic science, as that goes...there are several new techniques that have been developed to isolate fragments and resurrect genetic code...comparing skulls alone would have no hope otherwise, but endless speculation..
i mean as time has a way of erasing the picture faster than it can be developed, during some epochs...when the connection along the trail of dimensional association goes cold..
We are most directly Homo erectus. Their skeletal machinery is what Homo sapiens is based on. Neanderthal however is a specialized divergent side branch with a much different skeletal frame. Both Homo erectus and Homo sapiens are running frames with long legs to cover ground. Both spread out from their point of origin to become global species. Neanderthal is built stout with short lower legs. These are localized specialized traits. Homo neanderthalensis had a relatively limited range. Never was global. We are most directly not them.
I absolutely love these series. It is always very interesting to imagine that these species did actually walked on the same earth as we do today and it is breathtaking to think about. Keep up the good work!
Very good overview of morphological and behavioral characteristics of erectus. If I may say so, concerning thermoregulation, this appears to be more inferential than evidential. It is likely, of course, that if our erectus ancestors were endurance runners, then yes, there was probably reduced body hair and more sweating. I would also like to say that the landscape is nice to see in the background. Sometimes, especially when discussing movement across the landscape, it is nice to move out of the classroom and into the field. Thank you for sharing this.
Excellent presentation!!! The study of man's ancestry is heavily reliant on the science of guesswork. One anthropologist opined that it was like trying to figure out what life in the UK was like in the 20th century by going through a wastebasket from parliament. Concise conclusions are impossible but we have to still try and figure out this fascinating puzzle.
Hi Lindsay, am I right in that H. erectus and H.ergaster are the same species? If so, what determines which scientific name gets used? i.e., why H.erectus over H.ergaster?
This is a direct copy and paste I found. It is a bit simplistic. "Homo ergaster and Homo erectus are sometimes used interchangeably. In some cases, ergaster is used to refer to an earlier, African ancestor of the later erectus which also lived in Asia".
@@ArnieD17 what’s the source? This is my understanding from the literature. Once thought different species, now considered the same species but the species name have remained. H.ergaster in Africa, H.erectus in Asia.
This is all fascinating. I find the most fascinating part of this the lice part of evolutionary traits. I have a few questions specifically for the lice part.
You’ve explained so many very interesting points of our ancestors in a easy to comprehend way . I wish there were more documentaries like yours for the public . Great work and I will certainly follow all of your research! Thanks and good luck !
What finally happened to H. erectus? Was Indonesia the last place where they lived? Is Chris Stringer right in placing H. erectus in Indonesia as late as 70K years ago? Finally, Australian aborigines are said to have settled in Australia about 50K years ago. So, is it possible that they may have had some interaction with H. erectus in SE Asia? I have subscribed so that I won't miss your wonderful videos. Thank you.
How many differences are there between a couple of modern human skulls. Say like a sub Sahara African, a northern European and an Asian? What are the number of differ between those skulls?
Why are you discussing an animal that we cannot connect to humanity through DNA since it is the “DNA leaning center”. Additionally, it would seem that the analysis on human species is more subjective than with other species. Some argue that we differentiate species by skeletal characteristics others claim it’s by the amount of chromosomes individuals have. I know for a fact that many human individuals are born with only 22 chromosomes that are not inflicted with any kind of genetic disease as some might imply. So how do we exactly distinguish one human species from another?
If Homo Erectus lived on at least 2 different continents did that mean that there could have have been different races of H.E.? Such as H.E. in Africa could have had dark skin (like modern Africans) and H.E. that lived in Indonesia could have had lighter skin? And as they lived on more than 1 continent could they have had seafaring technology? Thank you
@@harish10bhushan I saw a documentary that pretty much said Homo Sapiens developed talking during the time we co-existed with Homo Neanderthalensis. It's pretty much the reason why we are so advanced.
Neanderthals had the anatomy and gene required for language, so almost definite they had language. They haven't recovered DNA from erectus yet ( to my knowledge) but I think they had decent speech. Proto-language is the term I see in a lot of papers. Probably smaller vocabulary (focused on local environments), less-structured grammer, etc, but still effective communication. Analogy: sapiens language is like broadband high speed internet. Erectus had dial-up. Purely speculation.
@@carolinesykes3636 don't you think temporal development and mastoid process in australopithecus could have been the beginning of some sort of communication. And also their frontal lobe is straighten for a clear 180 degree vision.
Oh yeah, the HE was the first of many human species who ran everywhere! Even today you can see entire tribes of people running all over the place for long distances. Oh, wait, none of them do, ever. HE may have been able to run long distances, but just as virtually no current humans anywhere spend a lot of time running (except as recreation or in short spurts), I doubt they ever did either to any great extent. For one thing, it burns way too many calories and limits your ability to carry tools. Did they run at times on the hunt? I'm sure they did, for short distances. Did they run after prey for miles and miles? Hell no! That's a most inefficient way of hunting, and a great way to starve to death. Most likely they would have used their larger brains to anticipate and stalk their prey, not traipse after it.HE was the most successful, far-ranging, and longest-lived species by far. I believe eventually someone somewhere will find some HE DNA that will confirm we're actually descended from them.
make some observations comparing homohabilous and homoerctus....note, homo erectus was comparatively evolved for endurance running...read all my notes Lindsey, do you get what i am saying with all this? this is important...humanity is currently doing destructive testing on the entire planet, trying to figure out how many humans the planet can TEMPORARILY support?
A raised domed high vaulted top crania with a forehead is the hallmark of modern man. All other hominids have a depressed and submerged top crania without a forehead. Even the Neanderthal lacks this Homo sapiens trait. Homo sapiens is truly unique. A new distinct chapter in the Homo lineage.
If the animal's behaviour is known, most middle-aged people have a good chance of tracking and killing fast four-legged prey because we sweat. The animal will have to rest to prevent hyperthermia. Then walk up and poke at it from the safe distance provided by the long shaft of a spear. That was probably the initial superpower that forever set intelligence as the focus of a genetic arms race. The best predictions regarding other's behaviour brought the most food.
I think erectus also succeeded by being able to wound prey initially, then following it long distances until it bled out or weakened enough for a kill shot with a spear. This ability to track wounded prey would have been a huge advantage.
"species", is sort of an accepted misnomer, or because they are technically extinct, and only for that reason, the accepted term becomes "species"; probably as a means of shedding guilt... but any, in the same time frame, could have interbreed...ok, so yeah, that's the same species then...right?..... how about "Technically Extinct Hominin Strains", or would that still mean that they must be "inferior" because because?....because because, it's still the answer for everything.
I believe you're wrong. From what I've read, there's never been any conclusive evidence of Sapiens and Erectus interbreeding (apparently because Erectus gene samples are too old to be sequenced) ... The popular theory is that the two species never got the chance to co-exist, let alone interbreed, because they were too far apart in time and place (it's now believed that the species between Erectus and Sapiens is "Homo Heidelbergensis").
@@Will_JC yeah, but there is some support to the hypothesis that erectus interbred with denisovan..and of course, substantiated evidence that denisovan interbreed with sapiens.. i don't need to hold my breath, just to wait until the new techniques verify a DNA connection, and then it matter what you believe..
The basic requirement for interbreeding is having the same number of chromosomes. Two different species can interbreed if they have the same number of chromosomes. Horses and donkeys can have offspring together, but they don't 'interbreed' because different numbers of chromosomes and the offspring is infertile. However being able to Interbreed doesn't make two species the same species. Tigers and lions are an example of the last point. Just takes the same number of chromosomes.
endurance running ? that is so 3 million years ago...we invented bows so we could smoke tobacco since then.. my DNA test says i am 100% european with respect to the urals....so i actually survived the neolithic in europe, un freaking real hey?...and this overshoot is probably going to be worse.
