- Archeological and genetic evidence indicates that people first entered North America from northeast Asia sometime during the last ice age, or late Pleistocene, at least 16,000 years ago, or possibly earlier. During the last glacial maximum (LGM) circa 18,000 years ago, sea level was approximately 120 m (about 390 ft) lower than it is today. As a result, the Bering Land Bridge and continental shelf of the Northwest Coast of North America created a continuous shoreline stretching from Northeast Asia to Southeast Alaska. Geological and archeological evidence suggests that this coastal corridor was ecologically viable and capable of supporting human groups and was the earliest ice-free pathway available for people to colonize the southern regions of the Americas.
Very cool. The Kelp Highway open by 16 kya, complete with Grizzly rest stops.
brown bear mandible in the Victoria BC museum excavated from a cave on the Queen Charlottes is almost 18 inches long and over 8,000 years old. The QC was grassland then (grizzly country) and connected to the mainland. As described, that bear would b e looking into your 2nd. story window.
around Sep 2021 - it was reported that human footprints discovered in the White Sands Nat'l Park in New Mexico have been dated to 21 to 23,000 cal years BP - based on carbon dating seeds in the stratigraphy - - that was in the middle of the ice age - before the formation of the inner corridor - human migration into the americas has to predate that - giving the coastal migration a major boost
It boosts the Sw European migration as the first Americans too.land to marine mammal hunters isn't imperative.
The idea that pacific corridor migration humans are the only humans having found warmer uninhabited lands to the South and ignored that staying along the British columbia coast but had stone point technology more like that of SW Europe is being discounted.
Why is the absence of that stone technology from 25k ypb absent from the supposed pool of humans from asia

hae you been drinking or smoking something - you aren't coherent
@@MegaStairman dna evidence does not support this theory , yet. although its possible that those early inhabitants died off before the clovis people repopulated the area.
@@mcolisekim so why did the tribes in southern Washington so adamantly opposed testing Kennewick man
Fantastic talk, thank you!
Great video. Thank You.
We now have a solid human habitation date of about 18k years ago, at Rimrock Draw rock shelter, in eastern Oregon. ... and we have an even more reliable date of ~21k years ago at White Sands, in New Mexco.
So have to push this western coastal migration story _back_ in time -- there were people in N. America during the Last Glacial Maximum
Humans were in New Mexico 22000 years ago.
you shouldn't smoke that stuff, it is bad for you.
@@SideWalkAstronomyNetherlands In New Mexico we have been roasting and smoking chile for 22000 years, you can tell by the pep in the footprints.
@@SideWalkAstronomyNetherlands- That statement was correct, though. No drug-smoking required. We do now have a very reliable date of ~21kya at White Sands, New Mexico
We also have a solid date of 18kya at Rimrock Draw rock shelter, in eastern Oregon
It could have been a smaller population that entered before the Canadian glaciers blocked the inland route 26000 YA. We see an explosion of human implements in the Americas after 14000. That earlier signal may have disappeared after the larger migrations started after the end of the last glacial maximum
We've used fire for 500,000 years, clothing for 200,000 years at least, my guess is cordage was very early on. Anybody that moved anywhere moved along water. Seacoasts are easy food sources but terrible fossil producers. Rivers are the same.
Homo sapiens and Neanderthals had plenty of intelligence and material and need for water crafts. To assume they didn't notice, take advantage of, and adapt/improve floating things is selling them short. They survived by exceeding their needs in every aspect of life.
Boats aren't complicated or sophisticated at all.
I suspect human remains or artifacts are found in interior of continents only because they had the freedom and luxury of moving by boats.
To me, it's counterintuitive they'd seek a path of most resistance.
Yep. Path of least resistance. 50k years of aboriginal australians with various water craft.
Google
"australian museum first-nations watercraft-culture"
Moreover takimy into account the fact that most of the LGM sea coast line is now underwater it's not that surprising that we are lacking of evidence for earlier colonisation of America
I think the best place to look for stuff like that would be the Sahara desert, it used to have a few big rivers but it all dried up
@@missourimongoose8858
I suspect the Sahara drying up 5000 yrs ago is why Egypt debuted at its peak.
All early civilizations are centered around waterways.... So.....
Very informative, thank you. By the way, as for the First Americans, Ainu aren't indigenous or aborigine at all. They came in 12th century and no relation with First Americans theme completely. They are quite different from Australian Aborigine and American native Indians' situation. Related people for the First Americans are Proto-Japanese Hokkaido（PJH, Hokkaido Sojin）had lived there, northern part of Japanese archipelago, since 35-30,000 years ago though their bones haven' t been found yet. Similar peoples' bones were found in Okinawa, as samples of 36,000~27,000 years ago. On the other hand, their ancestors are famous for crossing sea more than 20km to collect obsidians at Onbase island in Tokyo islands since 38,000 years ago. Any way, it's not Ainu, but Proto-Japanese Hokkaido（PJH）or Hokkaido Sojin as the ancestral candidate people of the First Americans. These're well known matter about Ainu and ancestors, but really very strange of no mentioning from university scholars' side.
You should read history of Hokkaido to find out true stories about the Ainu people.
Ainus aren’t Proto-Japanese at all they don’t look Asian and they did not speak Japanese when Japanese, Sogun, invaded Ainu territory Hokkaido) starting from in 7th~9th centuries.
It is shameful Japanese Sogun attacked the Ainu people and took the Russian land Hokkaido.

can you talk to the tilt of the north american plate to being higher in the west then the east i.e. what i underwater in the east and west may still provide varied data but good data for migration paths?
no you can't....lol.. the ice pushed down the land in fact, the thicker the ice the more it was pushed down...So the Hudson bay area is still bouncing back up, and further south is is going down a bit.. as the crust is connected all over..
I disagree about the miicroblades. They'd have picked up plenty of toolstone in the summer. It was just a more efficient tool. Central Americans also used microblades and they had all the toolstone they could want.
There is also some cultures who favored bone points over stone, the old bone knifes are the ancestors of the modern yakut knifes in Siberia
Yes they came way they also came right through the rocky's, They also came down the front range all populations are cut off from each other.
So does the southwest new mexico white sands footprints still make this true? Don't they have to be in north amercia 22k years ago to leave foot prints?
Native American Sea gardens could be lower off shore then present coastal garden structure's but I think land has risen and lowered with sea levels over last 35000 years native American habitation like the Denisovan like species who came before them they followed the birds
Your beringia was to baron for sustainable living. Plus our Indigenous stories say the tracks go westward. The old ones were seafarers and we're nomadic. Please show me the DNA results of your Asian connection to my people.
So...uh, ummm...
More than one route existed, separating groups geographically 500 miles apart.

think i just heard "uhhh" about six thousand times, really got on my nerves; soooo slow, this lecture.
Uh and uh. But uh, uh. Uh. Uh.
After the first 100 or so uhs I had to uh bail out.
Have any maps been found to date before any Europeans maps? I’m thinking maps may have been carved in Stone. I believe such a map exists. But how would we recognize it if we came across it?
Yeah, no. There is no evidence of any ancient maps.
@@slappy8941 can u describe one? Betty yet . Montoro stone is one
snap out of it, no more fox news..
@@SideWalkAstronomyNetherlands your funny! Ignorance is bliss!
His licence explanation of rapid sea level is weak at best.
Rebound does happen, but not quickly.
The impact melt theory is gaining traction, the necessary impact sites have been identified.
what is the rate
Wow, that was painful!
I was hoping for some new information, but he is just repeating information already available on youtube.
People migrating down the coast, sure. Marine boat people crossing the contential divide, not so much.
Are there any clovis sites west of the divide?
We're the alpine passes clear of ice at that time?
I expect costal marine people were more likely to reach south/central america before crossing the contential divide.
This guy is cut from the same mold as the people that insist that there was nothing before clovis.
There is clear evidence of pre clovis people.
Why is it so hard to believe there were waves of migration by numerous routes?
This guy is what my dad called an "educated idiot".
Gggrrrrrr
Indoctrination through his university and or meal ticket’s ideals.
seven sites west of the divide
Northern people stock up for winter.... This guy is not smart.
Clovis people clearly made catches of tool stone. They would have no problem dealing with winter by stocking up. Dam fool!
Um I um think um I um tired um of um your UMS. Um so um I um am um not um going to um finish um listening to um your um speach um.
More marine than a whale?! WTF....
