What do you guys think made the megafauna go extinct?
I wish you would explain BP a bit more.
@@hansolowe19 it's just years before present
It just means before the present era. BP.
It is meaured from the '50s, because of the atomic bomb testing.
I'm glad you mentioned the change in the fire regimen brought about by newly arrived humans. This potentially altered or even destroyed entire ecosystems and is rarely considered in discussions of the NA megafaunal extinction.
I really liked the video. It was very well done, presenting research studies with facts and not opinions and doing it in a very interesting way.
This man never makes a bad video. Thank you.
I have never seen so many dire wolf skulls in my life than at the La Brea Tar Pits museum.
That Wall Of Their Skulls Is Truly Impressive. The Fact That People Have Worked So Hard To Preserve And Clean The Fossils Is Astounding.
NO DOUBT
Thought provoking
The more we know the more tools we find to change and increase what we know
Seems like the more we know, the more we know we don't know, yah know?@@mikemarthaller8789

Hands down THE BEST channel for historical content. I love NORTH 02!!
Absolutely !!!
This is absolutely enthralling to me. I live in Western Kentucky and know of two dozen Clovis sites in a three county area. I've found artifacts on every one of them. What was their world actually like? Where did they come from? Was there anyone before them? What were the cultures like who replaced them....or who they evolved into? Thank you North02 for another amazing video. You're killing the game in your genre my man. Out doing yourself with each new one.
A Mastodon butchery site was found in 2020 in new Mexico dating back 130,000 years, in answer to your question was there anyone before them.
@@highwaydaytime7669 the Cerutti site?
@@highwaydaytime7669You seen the doco on Luzia? About a skull found in Brazil that suggests the Clovis people's weren't the first inhabitants of the Americas
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😊
search "footprints at White Sands, New Mexico". This evidence is dated 21-23 thousand years ago and if accurate represent pre-Clovis occupation.
Can’t wait. Visited the tar pits last year and was an amazing place. Love the channel and all of the amazing content you put out, perfect for an arch student
There are tar seeps around La Brea. Interesting to see tiny versions all over the neighborhood.
The Spanish word "brea" means tar.
East of Los Angeles is the city of Brea, CA, which had several such seeps. They were why some of the first oil fields were located in the area.
Gonna be a good Saturday!
Gonna isn't a word

Oh wow. La Brea tar pits is about 7 miles from my house. I go there a few times a year but just not recently. I Can't wait to see this. My favorite creator about one of my favorite places. I can't wait....
Stop stealing my culture, why are you wearing white face?
@@user-io6pj8bz8h cringe
Visit to La Brea on my bucket list!!
I've never been to those pits, but I live next to the gray fossil site. It's one of the largest fossil deposits of ice age fauna east of the Mississippi. It was a pit/watering home. You should do a video on it!
RIP to that one guy that made an example for everyone else not to follow.

Always A Great Day When North 02 Uploads. You Put So Much Work And Effort Into Your Content, And Honestly Don’t Get The Credit You Deserve. Thank You For Teaching And Entertaining People On Prehistoric Topics, And Keep Up The Amazing Work You Do Here.
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.
Thanks for doing these videos, they always brighten up my day!
Amazing as usual! Can not get enough! I am getting a new outlook on life. Thank you for the awesome historical content!
Providing excellent content without politicizing or any kind of bias is one of the reasons your channel is among my faves. Thank You!
It's dead animals dawg its really something only a moron could manage to make political.
Great Content, what tremendous beasts. In these difficult times your videos help me a lot.
Great start to a Saturday before works. Thx for an amazing video!
I went to the La Brea museum in 2003, and it was AMAZING!
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.
I always wanted to go back and visit there ever since I went as a child.
Very eye opening, love the videos
You truly are an amazing storyteller, the way you talk about historical events makes me so happy and has long revived my love of ancient history!
Brilliant work North, yet another great presentation to add to your collection of thoughtful, intelligent, and beautifully put together videos from you.
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.
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.
Great video man, thanks for posting!
Interesting that you bring up fires and the native populations. That was quite common in Minnesota before the Europeans arrived that the Dakota used grass fires and forest fires as a tool to clear and manage the land that they were on.
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.
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?
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 didn't even know I subbed to your channel. Fortunatly I did 😊 Greetings from the Netherlands
@@ConontheBinarian I checked the videos and than I remembered the ones I had seen 😉
Dude this channel makes me so happy, thank you North 02 ❤
Un altro meraviglioso video. Grazie tanto!
Excellent! Thank you. Delighted that I found and subbed your channel.
Your channel is the reason I got into paleo art. Cheers!
Thank you North!! Love when you upload (:
very interesting! well done as always!
Love to hear and watch North02 when it comes to ancient animals and ancient humans. Quite a wonderous experience with such a slow and calming voice
I have just come across your channel and can't stop binge watching it, fantastic content man, thanks.
Thank you for posting! Love all of your videos
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.
I just wanted to congratulate you on this and the previous videos since I watch them all. For those of us who are not scientists or historians but are interested in the past of species (including ours) that have lived and died over +- 4.5 billion years, it is extremely interesting... continue with this very interesting work and the way you make them...👍
Field trips to the tar pits are some of the best memories i have from school. I haven't been there in 20+ years.
The best presentation I’ve ever read that provides a plausible way for pre-historic human activity to affect regional mass extinctions. Well done. I’ll be thinking this through for next decade. Thx.
Awesome and well done! thank you.
Very good research young man keep up the vids, loved this vid.
Amazing and finally it’s clear to me. Very informative 12 minutes
Awesome video, thanks again.
Really fascinating stuff!
Great video, thanks north
תודה!
When we took our 2 little girls to Disneyland. Our 2nd stop was here. They, well all of us, really enjoyed it. Fascinating and a common point of discussion on the way home and at school.
Great content, fascinating subject. Grazie.
If someone hasn't done it already, maybe a history of the "dark ages" and an overview of the history of man from either 7 mya or from around the start of Egyptian time (or a little before) until the present. I really enjoy these. You do a great job with them.
Fascinating video. Thank you
Had to come to the channel page to see the second half.
Otherwise, great as always. ✨️
Great video again❤. Thx👍🇫🇮
Absolutely fascinating!
Absolutely love your content
Holy shit a sponsor that sells something cool, I didn't think that was possible!
Need longer videos! Keep up the great work!
Very informative. Thanks
Let's hope it's a long one!
That's what she said; am I right?
@@nicksweeney5176 Ready your yardsticks!
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.
I've lost count of how many times I have visited the George C. Page museum and surrounding tar pits. It's an amazing place of discovery! I can't recommend visiting it enough if one happens to be in the area.
thanks ! so fun !
Welcome back!
Great video, thank you
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
good stuff sir
informative and entertaining , thankyou
I absolutely love all your videos. My favorites are the hominid and early human videos
Outstanding!!
I was there last month. It's very cool.
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
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
Truly fascinating!
I’m from Australia and I’m really looking forward to visiting this museum when we visit LA in June!
I flipping love this channel. ❤
Going there this weekend!!
It's so cool to see the artist's rendering of the Los Angeles area in ancient times.
Awesome 👏 just visited two weeks ago!
Love these
im gonna be honest its late and all these graphs and terms are melting my brain, but it was still a very relaxing video to go through ❤
I haven't been to La Brea since the 1970's. I've always wanted to return. This video was fascinating and informative. Thanks!
what a banger bud!
Awesome.. That was awesome..
Yeahhhh budddy, new vids, let’s go!!!!!
Nice. Boneclones is awesome.
Awesome thanks
I grew up in SoCA and was never allowed to see the LaBrea tar pits. A few years ago after being out of the state for over 30+ years, my sons-in-love took me to visit. I loved it. Could have stayed for days. Grandkids were no so excited. Lol ( too young)
Why were you not allowed to visit?
@@seyersusej8329 couldn't drive, parents didn't care. We were in Orange County, too far to walk.
Fascinating! I just love this subject, especially with some species going extinct and some have such close extant relationships.
Hmmm... I usually comment on your videos but I don't really know what to say other than good job. Clear, concise and interesting. I have nothing to add and no questions.
7P to N02: Nice Work.
I really hope you continue making videos and uploading to spotify! Tremendous! If i may ask, could you dive deeper in on the topics of mammoths and homo floresiensis, please super interesting🎉😊
Nice work once again. Would love to hear you expand more about evidence on megafauna decline in Australia.
thank you very cool
Wow that was short
Please do. More information on this topic would be greatly appreciated.
When north drops… I watch.
Sunday here in New Zealand
A well considered explanation, events such as these are often the result of multiple interactions rather than a single, dramatic event.
Enjoyed the informative video. I'd bet the tar pits were a difficult dig.
I have been to the tar pits myself years ago while on vacation my favourite part is the bones of birds found in the tar pits.
