A mysterious DNA marker is rewriting everything we thought we knew about how humans first reached the Americas. Haplogroup X, a rare maternal lineage found in both Europe and among Native American tribes, has baffled scientists for decades. Its absence in Siberia and Alaska challenges the long-held belief that all migration came across the Bering Land Bridge. Could early humans have taken a different path? Maybe even arrived in multiple waves?

This discovery doesn’t confirm wild theories—but it does reveal just how complex our human journey really was.

00:00What if everything we thought we knew about the first Americans was wrong?
00:04Scientists have just uncovered a genetic twist in the story of how humans reach the Americas.
00:09It's all thanks to a rare DNA marker, Haplogroup X.
00:13This maternal lineage is found in both Europe and North America,
00:16but mysteriously not in Siberia or Alaska, where the first migrants supposedly crossed.
00:22So how did it get here?
00:23Unlike other common haplogroups linked to Native American ancestry,
00:27Haplogroup X doesn't fit the usual path across the Bering land bridge.
00:31Its unique branch, X2A, is found among tribes like the Ojibwe, Sioux, and Navajo,
00:37but it's absent in the supposed entry route from Asia.
00:40Some once claimed it proved ancient Europeans crossed the Atlantic,
00:44but that theory's been debunked.
00:46Instead, scientists now believe early migrations were far more complex.
00:51Multiple waves, different routes,
00:53maybe even early coastal explorers carrying rare DNA like X2A.
00:58It's not proof of ancient Europe in America,
01:01but it's a clue that reshapes how we trace our roots.
01:04In the end, Haplogroup X doesn't solve the mystery.
01:07It deepens it, and reminds us that human history is anything but simple.
01:12How can we get here?
01:13It's quite simple.
01:14How can we get here?
01:15How can we get here?
01:16How can we create an online, Worldwide,
01:18As a result,
01:21even more information to us,
01:23we'll be able to see in an online situation that might get better.
01:24We'll be able to find the way we can use it.
01:25If we were to learn a little more lively,
01:26we'll see a little later on the outside at the outside,
01:27we'll be able to do it.
01:28We'll see that as well.
01:29Fill up your hand at the back door.
01:30Let's see it.
01:31In the back door,
01:32the remaining space and a little more complexity
01:33we can do it.
01:34These are all the way around the world,
01:36have lost and the area of the world.
01:37If we're being able to find a sign,
01:38to feel the same way to his right,
