Some 130,000 years ago, scientists say, a mysterious group of ancient people visited the coastline of what is now Southern California. More than 100,000 years before they were supposed to have arrived in the Americas, these unknown people used five heavy stones to break the bones of a mastodon. They cracked open femurs to suck out the marrow and, using the rocks as hammers, scored deep notches in the bone. When finished, they abandoned the materials in the soft, fine soil; one tusk planted upright in the ground like a single flag in the archaeological record. Then the people vanished.
almost certainly bullshit.
During the Pleistocene epoch, global cooling led periodically to the expansion of glaciers and lowering of sea levels. This created land connections in various regions around the globe. Today, the average water depth of the Bering Strait is 40-50 m (130-160 ft), therefore the land bridge opened when the sea level dropped more than 50 m (160 ft) below the current level. A reconstruction of the sea-level history of the region indicated that a seaway existed from c. 135,000 - c. 70,000 BP, a land bridge from c. 70,000 - c. 60,000 BP, intermittent connection from c. 60,000 - c. 30,000 BP, a land bridge from c. 30,000 - c. 11,000 BP, followed by a Holocene sea-level rise that reopened the strait. Post-glacial rebound has continued to raise some sections of coast.

Scientists have known that DNA can survive in ancient sediments since 2003
QuoteScientists have known that DNA can survive in ancient sediments since 2003wow, this will really help us learn about prehistoric humans from 2003what a useless discovery
