Land Bridge

[Reschke]

Take a look at this linky Xargos. I read this book but it is out there with some of its theories while a few others are dead on.

It wouldn't surprise me in the least if Chinese sailors landed in the Americas before the Europeans.  Many people fail to realize how advanced the Chinese were back then, before opium.

Have any of y’all seen the woodlands of Alaska?  Compare Russia's vast birch forests to the ecosystems in Alaska. The Siberian Tiger would quickly dominate in this ecosystem. Why no Siberian Tigers in Alaska?  They would absolutely have PRIME food there in Alaska; it’s population would have flourished.

If there was ever a land bridge ~ the Siberian Tiger would certainly be there.  The absence of the Siberian Tiger is in direct opposition to the survival of the fittest crowd's standard line.  This one thing alone is enough to dispute a land bridge ever having been present almost without question.

About 100 years ago, my Grandpa's family traveled across the Bering Strait to settle in Alaska.  Is it only possible for migrants to have traveled to Alaska by land?  Don't think so. The rest of those migrants came over in the same manner ~ boat.

Are you seriously using the argument that since there were no Siberian Tigers in Alaska it's proof that there wasn't a land bridge?


There were certain times during the Pleistocene Epoch when the temperatures were cold enough that most of the Earth's waters froze (also known as Ice Age(s)).  The sea level dropped more than 300ft around the world, and in such places such as the Bering Strait, the land was exposed because the Strait lies in relatively shallow waters.  Through this "land bridge" and glaciers, humans and animals were able to cross from Asia into North America.  

If you really want some examples of some of the animal species that crossed via this land bridge then you only need to look at the Saber-Tooth Tiger (Smilodon populator), the Wooly Mammoth (Mammuthus primigenius), Giant Cheetah (Acinonyx pardinensis), North American Lion (Panthera leo atrox), North American Cave Lion Panthera leo spelea).

Now, about your "Siberian Tiger" theory...the reason why there weren't Siberian Tigers in Alaska, there were no Siberian Tigers at the time of the Bering Strait/Alaska Land Bridge.  It's really that simple, otherwise it may have crossed along with the other animals.  The Cave Lion's range was wide spread, stretching from Europe, Asia and North America.  The only way it could have gotten to North America is by crossing the land bridge during one of the Pleistocene's ice ages.  Same with the other animals that I listed.

Here is a site that lists some of the animals that came across.

Most people look to the simple creature; the lemming.  

Each year adult lemmings unwittingly commit suicide by charging head-long into the Bering Sea.  Scientists say it's because for millenia, lemmings migrated across the "land bridge".

Supposedly, because this annual migration was imbedded in their DNA, lemmings continue to die in the ocean....looking for their long lost "land bridge".

Lemming do not "commit mass suicide" as portayed in the Disney documentary from the '50s.  The filmmakers of that documentary induced the "mass suicide" by using a helicopter flying just a few feet off the ground to herd the Lemmings over the cliff to "record" their supposed suicidal behavior.

I'm assuming part of the reason any timeline I use will never match up is that I'm basing all off of a creationism timeline rather than the "billions and billions of years ago, when life started as germs" timeline, also.

Anytime you use a false science, you'll encounter those errors.

Why am I not surprised that you will deduce that I am the one using false science.

Hmmmmm....................

Actually if you read the Bible as it is written rather then listen to what some call the traditions of men I think you will find that the earth is VERY old!

The creationist part many refer to as the beginning of time in the Bible is not the beginning of time in the Bible.

What you see referred to as the creation is the beginning of the 2nd Earth Age.

J. R. R. Tolken stated that he used the Bible as the base for his Trilogy of the Rings.

It's a given...religion disguised as science is by its very nature false science.

Ack-ack, the problem is that the sabre tooth tigers and wooly mammoths all crossed over the land bridge what, 30,000-100,000 years ago, and were extinct how long ago? If man came across that landbridge at the same time then how come we have no evidence of man going back more than the recently discovered Oregon poop?

I'm merely using Geology to prove this.   Historical Geology was a fun class.   I'm sorry you don't feel that Radiometric dating isn't accurate.   It is.

That's easy.   Simply put, whereever on the "Land Bridge" they crossed, they might have been close to the Ice Caps or Glaciers.   If so, within the span of a few years (our time, days were longer back then) the "progression and recession" would destroy any carcass (potential fossils) and evidence.   The Earth is scored by the sheer mass of the movement.    Prime example?   Drumlins in SE Wisconsin.

Except there's fosils of other mammals still existing- and evidence of early human populations in Africa, Asia and Europe- there has always been a real lack of evidence of human residents in the Americas going back very far, relatively speaking.

14,000 years ago, humans were probably much more intelligent and resourceful than Siberian Tigers were.   So to say that humans could not do something that Tigers were not able to, is really comparing Apples with Oranges.

Humans somehow did manage to reach Australia 40,000 years ago.  So some kind of primitive boats must have existed back then, despite the fact that no such evidence has ever been found.

The Bering sea, though, is sort of a nasty place to be out and about in a canoe.   The odds of getting across it in a primitive canoe seem very remote to me, unless the distance was extremely short back then.   But if so, that would virtually be a land bridge too, then.   Just one that only humans were able to cross.

Actually, that's not quite true.  There are other archeological finds of Clovis man that go back just as far as 14,000+ years.  Prior to the evidence in Oregon, the oldest known settlement of ancient North American was in the Russell Cave National Monument.  Some of the stuff found in there dates from 9,000 to 12,000 years ago.  There also have been some recent finds off the shores of the Savannah River in South Carolina that predates Clovis man, some of the tools date from 16,000 years ago.  Some fossilized burnt plant remains might be as old as 50,000 years, though there still remains testing on the fossilized plant remains and still under dispute.

There are also other pre-Clovis man sites in Meadowcroft Rockshelter, Pa., and Cactus Hill, Va.  One of the speculated reasons as to why the Eastern part of the US has more pre-Clovis sites than the midwest and west, is that they crossed using the Wisconsin Glacier and then spread out towards the East Coast.  Whereas Clovis man is thought to have come across the Bering Land Bridge and then migrated along the coastline and rivers into North America, Central America and South America.

LOL this thread is teh funnay!
Speaking from an anthropological perspective, some people are on the right track. The best thing to do is take a step away from the biblical mythology and look at the evidence in the archaeological record.
There is ample evidence of a land bridge between the Asian and American continents during the last ice age. Tectonic Plate movement had an impact on only the most early of earths' history, but when it comes to the migration of modern man, it was left to the ingenuity of the people themselves.
Many travelled over now submerged terrain, others used water craft, but migrate they did. There is evidence of Homo Sapiens Sapiens inhabiting Australia as far back as 40000 years ago at sites such as Lake Mungo.

At the time of the Land Bridge, the most fearsome predatory bear in the world roamed Alaska.  The short-faced bear.
