The main disaster the Neanderthals had to face wasn't a climatic disaster. It was us.
Indeed, well said. We do tend to have that effect on all kinds of peoples, sadly.
Thank you for sharing this with us plebes. I found disaster it really interesting!
You don't know that.
Probably that and climate disasters working in tandem
Wow! Stunning new insight 18:14 into human development. As a general reader, I found the subject and presentation riveting .
A question about « Neandertal sites found only south of 52° North » in M JJ Hublin lecture: how much of an hominid site would be preserved after being rolled over by successive glaciers hundred of meters high that melted and formed back again over the site?
Also, Peter Menocal conciseness and understandability in -spoling- presenting their present research on African Climate Change and Human Evolution has me gratefull and "deep in"!
Will have a short break before listening to M Rick Potts.
African humid period had crocodiles, elephants etc across the Sahara only 6000 years ago. The Cooling Atlantic led to less rain since it ended the monsoons. ...it happened abruptly in geoligocal terms...all while co2 remained stable.
Narural climate change can be much more abrupt than what man can do.
I see some videos have CC and some do not, this is really appreciated. This video has CC.
Why would you want that?
@@roberthofmann8403 People who can read often find them helpful
Lots of food for thought, however one note of historical correction for Mr. Potts: First human space walk, en.wikipedia.org/wiki/Alexey_Leonov , was by a Russian.
Can you prove it?
It was because the Soviets had made all the initial advancements in space travel and exploration that Pres. Kennedy embarked on the US program to land on the Moon.
It wasn’t so much that USA-finally-beat USSR in the “Space Race” as USSR won the race early on and then walked away. There was no race as such in 1969 when Neil Armstrong set foot on the Moon..
@@jeremyashford2145 you are lying. The Soviet program was called ‘Zond’ and the rockets they were using were part of the N1-program. Their last test flight failed in 1972. They were attempting to orbit the moon with these missions with tentatively later doing a manned moon missions. However they had lack of money and spent most of their resources on ICBM research and development so their manned moon mission was not their priority. But to say they didn’t have any part in the race is simply a lie, it just wasn’t their main priority.
@@jeremyashford2145 Soviet race to Moon ended when the rocket going to use, blew up on Launch pad, vaporizing at least 20 top Soviet scientists, politicians & workers
Thus eliminating from race to land on moon as explosion set Soviet program back far enough that 6 months or so later , Apollo 11 landed on Moon & returned successfully
Soviets, turned towards ICBM & Space station
Gave up on moon landing, as to expensive
Money needed & used elsewhere, as prestige of being 1st wasn’t there anymore
What happens when politics over rides those who r the Professionals & know best
& when those same scientists, r afraid of the consequences of failure
@@jeremyashford2145 Yes, the Soviets beat the US by being the first nation to fake a moon landing.
African grasslands [ with whatever that might more exactly entail ] would be ballpark 2 to 3 million years. Not too far out with that finding. It would not be any more than that. And that is photosynthetic carbon dating. They reckon wildebeest have been charging around in static circles for nigh on two million years going nowhere in the total context of things. And lions have been separated from tigers for less than two million years, since the two separate lineages can still cross-breed with each other.
Between 7 and 8 minutes he is actually referring to the fabled Precession, much mentioned in dispatches to do with astrological calculation and the interpretation of ancient calenders. Wow !
Astrological? You dig up astrological information to compare it to scientific knowledge? WTH, why would you do that JW? Astrology is pretend. It's not anywhere near factual. 🙄
@@MaryAnnNytowl Actually I might have got the terminology amiss. The Precession is actual ASTRONOMY but it finds application between astronomy and astrological consideration and contention.
I really appreciate this project it is wonderful and the presentation is
absolutely ideal, except. How about some CLOSED CAPTIONS please ? I
mean come on, this is California I would be surprised to think this is
asking too much.
Good suggestion. For a project such as this, they may be able to afford closed captions. For many other good videos, though, closed captioning is usually done by volunteers, if at all. I agree that it should be done much more, but I wonder where the resources would come from. It is actually fairly difficult to caption a lecture with proper timing, terminology, etc. Maybe someday in the future automated captioning will become good enough to rely on.
23:00 what about south american indians and melanesians (short statured peoples) living in tropical zones? and how to explain tall scandinavians?
Mm
There are certainly (scientific) explanations, IE genetic/local environment/nutrition.à
They did not fall out from the skies...
Dietary effects
There is always variability and this was not a talk about that variability in human morphology. If your question is sincere be advised, this is not the way to get your answer.
@Bob RashonOne result being fewer tall men, cause armies like their cannon fodder big and dumb.
Thanks much for informing us as to the particulars of C analysis. Well explained!
For a fleeting moment I thought, 'Robin Williams?'
first two minutes.. irritating piano noises... just skip those..
HEY !! Who said I mastered language ?!?
Po\int him out ! I'll show him a little english.
If it was all due to climate then why worry about climate change since we will supposedly adapt?! 😒🙄
Seems like your confused. How long will it take to adapt. How many life's will be lost. And when a certain threshold is reached no evolutionary adaption will be possible...there won't be anything left to "adapt".
Why would one even want to test this hypothesis? Every extinction even whipped out millions of lifeforms...only certain genus survived. Did the Neanderthals adapt? Right now thousands of species are going extinct...
@@Raydensheraj why even be concerned! Those who are evolved physically should survive! I’m not about that New World 500... population plan, because that’s only about the elite surviving! I’m talking about nature/nurture! The Most High knows what He wants to survive and what must die off! We should stop trying to be Him and let Him led! He cleansed the earth before with a flood! We know another cleansing is due because so many are trying to operate outside His plan!
It's something for any given specie to migrate / evolve or die during a 5k years natural climate change. It might be a totally different one to migrate or die in a 100 years turbo charged climate change of the same scale.
@@MercyAlwyz23 so being you worship and that you want to lead you is periodicaly killing of 99% of life forms every now and then.
nice
couldnt he just show himself and tell us what to do? that would be a lot easier
@@TukozAki nah. Look up the younger dryas. Humans have been through faster and more severe climate changes during the dawn of civilization
the magnetic field rules over all, climate, evolution
Ecosystems rule climate and evolution.
@@Raydensheraj and the magnetic field influence ecosystems.
Kellee go home, you're drunk.
Human technological development occurred over a very long time and if we just follow the line of the “anatomically modern human” (AMH) that archeologists so love, it was clearly going nowhere fast at the time of the great migration, 100-50Kya.
If anthropologists were only willing to open their eyes to the reality they would have to admit that it was only was the entanglement of the evolutionary branches, AMH and Neanderthal that technological advance continued.
The AMH were a more athletic and dextrous people whereas the Neanderthal had the intellectual advantage. The mix of hand and brain was the making of mankind. From that point where Neanderthal were re-assimilated into the human timeline-rather than becoming extinct-humanity took off.
Can other viewers identify one significant advancement in science that has been the unique work of a human without Neanderthal DNA?
Since Neanderthal DNA is found mostly in Europeans, eastern asians and native Americans......they didnt contribute much since civilizations of homo sapiens were thriving in Sumer and Egypt
The Neanderthal DNA found in modern humans only reach 1 to 3 %.
Also comparing what parts of human genome are more alike that of the Neanderthal and what are completely different... we can see what parts of Neanderthal dna was lost because it was NOT evolutionary advantageous and what parts dominated because they were evolutionary advantageous.
Our immune system is most closely related to Neanderthal dna.. which suggests that it conferred to us a great advantage, and therefore we kept it.
The least Neanderthal like part of our genome is our "reproductive" system and "nervous system"... meaning our testicles and brains have nothing left from Neanderthals.. we shed that dna out as it was not advantageous.
So there goes your theory that Neanderthal made us "more intellectual".. lol.
Although, immune system has a good role to play in preventing cognitive decline.. as we know that a compromised immune system not only leads to disease and death but also lower cognitive functions.
@Din Sel
The majority of our DNA is called junk DNA simply because we don’t know what it does.
Whatever the mechanism, civilisation resulted from the hybridisation of anatomically modern humans and Neanderthal. There is no civilisation without Neanderthal. I don’t know everything and you don’t know everything.
Racists really pollute the world
Hello, if you don't know by now you're a racist and a eugenicist. Keep your stupid questions to yourself and choke on them.
Mind your language. It is not inclusive.
Not everyone’s ancestors left the African continent.
All ancestors are everyone's ancestors at this scale of time.
@Polymorphic Doombooger
No.
That sounds like politics to me, not science.
Don’t buy it .... human evolution is due to a higher intelligence be it god or extra terrestrial
Seek help for those schizoid delusions, especially the God delusion.
You must of never studied it....read 2 books, 'The Greatest Show on Earth' and 'The Ancestors Tale' both by Richard Dawkins, with a serious intent to learn. I bet youll start to see how it is very possible with no "higher intelligence".
@@whatabouttheearth I would also include "The Selfish Gene."
You must not understand emergent properties very well. There is absolutely ZERO need or trace of a 'higher' being being necessary for a 'lower' being to be 'brought up.' That's not how anything works at all, whatsoever.
