How First People Came to America
Introduction
Scientists studied the DNA of Indigenous people in Latin America. They wanted to see how these people moved and lived in the past.
Main Body
The scientists looked at DNA from 128 people. These people come from 45 different groups. The study shows that people moved into South America in three big groups. The first group arrived more than 9,000 years ago. The second group came from Central America. The third group arrived about 1,300 years ago. The DNA also shows how people changed to survive. Some genes helped their bodies fight sickness. Some genes helped them have children. The study also shows the DNA of very old humans, like Neanderthals. Finally, the study shows that European settlers changed the population. Many Indigenous people died from diseases or were forced to move. This changed their DNA.
Conclusion
The study shows that Indigenous history is complex. People moved many times. They changed their bodies to live in new places.
