I believe after the great flood (proven in ice cores, evidence in every continent😮research if non believer) but, because of this and the seas rising hundreds of feet, most evidence(fossils -which r extremely hard to produce naturally means we r taking .001% fossil evidence, which is, to me, a researcher on as much as I can get, seems jumping to huge conclusions on every single so-called historical fact with ever animal, dinosaur, etc. . Only 1 complete skeleton of T. Rex bones have been found. Only 100 different post juvenile individuals, only usually 1 s8ngle bone to differentiate. Only 32 mostly intact r displayed in museums, that’s it😂 But in books, they lived from blah to blah, great conclusions 😅 it’s all guessing with mega fauna as well. Great flood, tectonic movements, sheer winds/hurricanes volcano, etc.,really imo scattered our history, over and over again. We should be searching the ocean since duh. It ocean world (70%)here, not Earth (28%)or fresh water (2%)😂 I learned that about fossils from an archaeologist when we were fossilized hunting in Montana years ago 😅 most realistic, not hyperbole trying to get a new grant to dig/discover/ and publish your beliefs, not facts😊

This 12.49 minute video was more revealing about this subject than anything else I have ever seen. While there are so many things left unresolved, it provides a basis for further investigation and understanding of this time period. The methodology used to investigate this time period is also a compelling tool for use in discovering more about our ancestors. I've believe that human development has been most impacted by a combination of climate change and natural disasters like earthquakes, glaciation and floods, etc. Use those qualifiers along with man made changes to the environment and you should be able to trace the development of our species over time. Thanks again to North for providing this video.

[@JackHaveman52]

Before Columbus, natives would burn off land to attract grazers to the succulent new grass that grows after the burn. It could be that the hunters, of that period, realised that burn offs would attract the smaller grazers, which would be more numerous and not as dangerous to hunt as the really big animals. One mammoth might be a windfall but a hundred bison might be even better. This video suggests that this may have happened. Get rid of the forests and bring in the smaller grazers. You can see the herds for miles away on the grasslands which wouldn't happen in a forest setting.

Field trips to the tar pits are some of the best memories i have from school. I haven't been there in 20+ years.

[@michaelmisanik9787]

It is really amazing how the study was able to map out key events that heavily impacted the megafauna that once roam the LA Basin. Since my dad brought me the Discovery documentary "What Killed the Megabeasts" I have been fascinated with what exactly caused the extinction of all the incredible fauna that roamed North America. The Climate theory kind of made sense to me to an extent. There had been shifts from Glacial and Interglacial periods throughout the Pleistocene but this last shift(the last Glacial to be specific) drove out the megafauna. The Bølling-Allerød warming was an event I had never heard of before and from the evidence found it seems like many species quickly disappeared from the region and may have ended up seeking refuge in more suitable habitats until the arrival of humans was the final nail in the coffin for many. It amazes me that humans in North American had a hand in reshaping the ecosystems to a more fire-adapted landscape. I mean in backs a lot of sense with just about all Native American tribes utilizing fire in some manner for hunting. When it comes to the two other theories that I have heard I am a bit more skeptical. The Younger Dryas Impact is a really interesting and headline grabbing idea but the more I look the more I realize that if it had any effect on the environment of North America it would have only effect a relatively small area such as larger Tunguska event. The other theory is that disease played a role as well. In "What Killed the Megabeasts" the disease theory is suggest to have been a very infectious disease that humans or the dogs humans brought quickly spread to the megafauna and wiped many species out in a relatively short span of time. A disease similar to canine distemper was suggested but I am still a bit skeptical about it. Would you be interested in doing a video about that suggested theory? Keep up the good work.

[@raykinney9907]

I wonder, since Covid 19 opened my awareness of metabolic disease causation science, that a shift in large mammal mitochondrial ATP production, toward reduced energy availability, just might have been brought about by a quantum mechanical change, perhaps in wavelengths of light makeup of outdoor light. Could this have been the result of production of some particular volcanic gas combination they modified important metabolic functionality enough to favor smaller body sizes for survival? Could relative atmospheric near infra red light content have been interfered with to the point of have exposures of blue light spectrum increasing for a time W?O enough red light to balance it? Or, some other similar quantum biology shift for long enough to put large bodied mammals at a disadvantage? Then, that temporary influence more slowly modifying again somewhat?

[@xenon3659]

Very well written i feel like climate change played a major role in the extinction of megafauna humans just played the final nail in the coffin for their disappearance

I went to the La Brea museum in 2003, and it was AMAZING!

[@michaelhalsall5684]

We went to La Brea museum in 2017 and really enjoyed it. Our tour leader told us ' Don't go there, it's only dead animals' but we found it to be very interesting and exciting. The fact there is still bubbling tar there today makes very much a 'living museum'. One of the research staff told us that because the bones were found in a petroleum-based substance (tar) it has sadly destroyed any retrievable DNA, which is sad. Regards from Australia.

[@in-craig-ible6160]

I always wanted to go back and visit there ever since I went as a child.

[@jamiehall9029]

Very eye opening, love the videos

[@wlhgmk]

Going back 13,000 years only puts you at the time when the North American continental glaciers really got into their melt regime. The peak of the most recent glacial maximum was 20,000 years ago and from then on it was all downhill for the glaciers, albeit slowly at first. A better overview is obtained by going back some 400,000 years. Glacial cycles took about 100,000 years each so 400,000 years encompasses three (four including our present one) interglacial (warm) periods. In each, the weather warmed up, the glaciers retreated and sea level rose. The real fact of significance is that the mega-fauna survived all these huge temperature shifts and a lot more before 400,000 years ago. The only new factor in the present warm period was the advent of man into North America.

[@thomasferris3750]

Yes I was hoping he'd mention smth about the clovis being firsr

[@davidbryden7904]

Some of the warming in the Los Angeles basin in the last 100 years could be attributed to the fact that the whole area has experienced dramatic changes and growth in that period. It's basically all one urban sprawl from the ocean to the surrounding mountain ranges. The basin, particularly the foothills and canyons used have a wide variety of micro climates and unique flora.

[@greasher926]

Yep it’s called urban heat island effect. Although global warming is a thing, most of the warming in the big cities around the world can be attributed to this phenomenon. Just to put things in perspective in 2020 LA county’s population was 10,014,009, in 1920 it was 936,455 and in 1850 was 3,530. That’s a lot of concrete and asphalt that has been added in the past 100+ years that is now giving off residual heat.

Would it be possible to give an educated guess on when man discovered fire based on some kind of patterns of occurance of natural fire VS what I would assume would be an increase in fire as man begins practicing the use of it.

[@b.a.erlebacher1139]

One thing archaeologists look for are ancient hearths, because they are ideal for carbon dating. Lots of hearths have been dated, including ones in really ancient cave sites, including those used by predecessors of modern H.sapiens. Sorry I don't have a date for you, but maybe this will help you find one.

[@timboslice980]

The Florida bog bodies, bluefish caves in Canada, footprints in New Mexico push human habitation back well before Clovis. I wonder if the Clovis culture was entirely separate from these other cultures and we’re looking at multiple groups coming in at different times. No doubt the humans in North America before Clovis were using fire. But I can’t deny the data. Clovis arrival and the drop in numbers would make a lot of sense. I wonder if the previous cultures in America were just less destructive or far fewer in number

[@nataliajimenez1870]

DNA studies show that the Clovis people had the same DNA of pre-Clovis cultures. It's just that they developed new stone technology so they become a different culture in the archeological record. It's as if saying that the English before the Industrial Revolution were a different people that the English after the Industrial Revolution

Great job. The fire aspect is both interesting and obvious. Hadn't thought of that before.

Yeah, the whole region becoming much drier made the likelihood of small fires from humans growing into huge forest fires. This is something that we see to this day in the Western United States. People make a campfire and winds pick it up and the fire destroys thousands of acres of dry forest

[@Afrologist]

4:30 Born & raised in Cali; warming would result in a Temperate Savannah ecosystem being replaced by a more Chapparal climate like we see in SoCal today, while a subsequent cooling climate would see it become more like an Oceanic climate akin to the Pacific NW. This rapid fluctuation between three different climate types would see a massive conversion of habitat which would make supporting large animals in California almost impossible. Bison, Camels, & Horses would survive in Eurasia in addition to elsewhere in NA, but Cali wouldn't see anything larger than an Elk return to its lands even to the modern day.
