This baby's DNA shows how America is populated

The remains of this female-gender baby were discovered in 2013 at a Upward Sun River archaeological park in Alaska and was baptized under the name “Morning reduction” from the local indigenous community, while scientists are known as USR1 reference to the location. She was buried with another newborn, female baby who was also studied by the science team of Copenhagen, Cambridge, and Alaska. Part of the scientific community claims that the first people to walk the American continent belonged to a successor group of Asia at the end of the glacier period (Pleistoceno Superior).

By that era, the ice level of the oceans was lowered, and a land bridge that now belongs to the Bering Strait allowed it to cross from Siberia to Alaska. However, some questions remain about the date of this population's arrival and how they conquered the American continent. The research team, whose works were published in Nature, managed to extract the full genome of this USR1 baby.

However, they failed to extract the newborn baby's genome because of the insufficient amount of DNA, but genetic tests showed that the two girls were connected, maybe they were cousins. The little morning girl brought to light a surprise, her genetic legacy does not correspond to the first two known American branches. Scientists found that it belonged to a group until then unknown that they named as the ancient “berigian”. We didn't know this population existed.

Other analyses allow the first direct genetic evidence of the first Americans to come all from the same population that has arrived from a single migraine movement during the ice age. This migration wave may have occurred more than 20,000 years ago, highlighted Cambridge University in its communiqué. /The world.al
