Land Bridge question...?

Question

It seems that most evolutionist believe in the land bridge theory as to how people came to be in North and South America.

How can the land bridge exist if the wind normaly travels from east to west or west to east. Using the land bridge theory...we are suppose to believe that the wind carried moisture (clouds) from south to north and dumped to form the land bridge. When in fact...wind USUALLY travesl from East to West or West to East. No evidence exist that the wind traveled from south to north for THOUSANDS of years to form the land bridge.

So my question is this.

Is the land bridge real or was it invented to justify evolution?

Answer 1

. . .  the wind didn't move land. the plates moved and with them the land went with them. at first all the continents were connected and then the plates stated to move more and more and drifted apart. . . . or was it ice and like the water just froze over shoot i forgot stupid public school teachers cant teach blahh well either way the wind didn't move the land ( or ice) lol sorry. =]

Answer 2

You forgot the Ice Age which reduced the level of the oceans.  Also if the ocean is frozen then people can cross it.

The Bearing Strait Land bridge is pretty real, you see the remnants in the islands of Alaska.  During the Ice Age a lot of water was tied up on the surface of the earth as ice.  Mankind lived then and at the end of it, so the migration would have had to have taken place then.

Also a totally dry land bridge is not needed for mankind to travel to the Americas.  If there was a chain of islands then the travelers could safely cross that way and gather fish on the way.  They would then go ashore to find fresh water.

Another evidence of the land bridge is found in the skulls of Native Americans that are similar to the skulls of Mongoloid people.  The only way that two members of the same subspecies could have gotten so far apart is that there was once a path; hence the land bridge theory.

According to Wikipedia:  http://en.wikipedia.org/wiki/Land_Bridge

"A land bridge, in biogeography, is an isthmus or other land connection between what at other times are separate areas which allows animals and plants to cross and colonise new lands. Land bridges are commonly created by regression, in which sea levels fall exposing previously submerged sections of continental shelf. Land bridges are also formed by: (a) upthrust at the edge of continental plates; and (b) glacial retreat alleviating pressure on shallow marine formations (e.g. the emergence of Oland, Sweden)

The most recent significantly low sea levels were about 20,000 years ago (during the Upper Paleolithic) when worldwide sea levels were about 120 meters below today's level. By 10,000 years ago, the sea level had risen to 20 meters below today's level. Sea level rise can occur as a result of global warming, or apparent sea level rise may occur as a result of glacial depression or certain tectonic movements.

Perhaps the best-known example is the Bering land bridge, which joined present-day Alaska and eastern Siberia at various times during the Pleistocene ice ages, enabling humans to migrate from Eurasia to the Americas (see models of migration to the New World).

Another example is Doggerland, a former landmass in the southern North Sea which connected the island of Great Britain to mainland Europe during the last ice age."

According to Wikipedia:  http://en.wikipedia.org/wiki/Bering_land...

"The Bering land bridge was a land bridge roughly 1,000 miles (1,600 km) north to south at its greatest extent, which joined present-day Alaska and eastern Siberia at various times during the Pleistocene ice ages. It was not glaciated because snowfall was extremely light due to the southwesterly winds from the Pacific Ocean having lost their moisture over the fully glaciated Alaska Range. The grassland steppe including the land bridge and stretching for several hundred miles either side of it has been called Beringia....

The Bering land bridge is significant for several reasons, not least because it is believed to have enabled human migration to the Americas from Asia about 25,000 years ago.[5] A study by Hey (2005)[6] have indicated that of the people migrating across this land bridge during that time period, only 70 left their genetic print in modern descendants, a minute effective founder population—easily misread as though implying that only 70 people crossed to North America. Sea-going coastal settlers may also have crossed much earlier, but scientific opinion remains divided on this point, and the coastal sites that would offer further information now lie submerged in up to a hundred metres of water offshore. Land animals were able to migrate through Beringia as well, bringing mammals that evolved in Asia to North America, mammals such as proboscideans and lions, which evolved into now-extinct endemic North American species, and allowing equids and camelids that evolved in North America (and later became extinct there) to migrate to Asia.

A new study published November 26, 2007 (see PLoS Genetics), which was led by University of Michigan and University College London researchers, seems to suggest that the Bering land bridge migration occurred during one specific time period which was 12,000 years ago, that every human who migrated across the land bridge all came from Eastern Siberia during that time period, and that every native American is directly descended from that same group of Eastern Siberian migrants.[7] The claim suggests that a "unique genetic variant widespread in natives across both continents — suggesting that the first humans in the Americas came in a single migration or multiple waves from a single source, not in waves of migrations from different sources"."

Answer 3

The land bridge existed during the last Ice Age.  Popular theory is that it was exposed during a period of lower sea levels, or more likely, the people crossed on islands connected by frozen water.  I'm not sure how prevailing winds factor into the existence of the land bridge.
