A 2013 genetic study suggested the possibility of contact between Ecuador and East Asia, that would have happened no earlier than 6,000 years ago (4000 BC) via either a trans-oceanic or a late-stage coastal migration that did not leave genetic imprints in North America. [57] Further research did not support this but was rather "a case of a rare ...

Map of early human migrations based on the Out of Africa theory; figures are in thousands of years ago (kya). [2]The peopling of the Americas began when Paleolithic hunter-gatherers (Paleo-Indians) entered North America from the North Asian Mammoth steppe via the Beringia land bridge, which had formed between northeastern Siberia and western Alaska due to the lowering of sea level during the ...

Seabirds (mostly northern fulmars) flocking at a long-lining vessel. Some seabird species have benefited from fisheries, particularly from discarded fish and offal. These discards compose 30% of the food of seabirds in the North Sea, for example, and compose up to 70% of the total food of some seabird populations. [76]
The aquatic toothed bird Hesperornis is the only known Cretaceous bird whose remains are found with any frequency in North America. [82] Near the end of the Cretaceous, the Western Interior Seaway began to withdraw. This regression would end up resulting in both halves of North America reuniting.
