i believed in it.
many scientist havent determine what cause ice ages.
a massive snow storm and brain age
The ice age began at the end of the Jurassic period, a theory of why the dinosaurs became extinct. <33
The Bering strait is how they came but i don't know what you mean by ice age
because it melted for the ice-age
because it melted for the ice-age
For those who subscribe to the theory, YES.
no one really knows there is the theory of it of could of been a ice age an other theory of the meteorite hitting earth killing all of the dinosorus
For ancient American civilization, scientists speculate that people walked across the Bering Strait during the ice age. This would explain HOW Native Americans were on the North and South American continents long before the discovery of the New World. They base this theory on the fact that in the ice age the Bering Strait was above sea level. An opposing theory might be that Native Americans were on the continent before Pangaea completely broke apart.
The land bridge theory suggests that during the last Ice Age, a land bridge formed between Siberia and Alaska due to lower sea levels, allowing for the migration of people from Asia to North America. This theory helps scientists explain how early human populations could have crossed into North America from Asia via this land bridge, known as Beringia.
The clasic theory is that people from northern Asia crosses the Bering Straights - possibly during an ice age (with low sea levels).
