Prehistoric humans rarely mate with their cousins

The researchers reanalyzed the previously published DNA data of ancient humans over the past 45,000 years to find out how close their parents are
.
The results of the study are surprising: ancient humans rarely chose close relatives as their spouses

In order to analyze such a huge data set, the researchers developed a new computational tool to screen the parental relationship of ancient DNA
.
It can detect long-term identical DNA in two DNA copies, one inherited from the mother and one inherited from the father

In addition to determining inbreeding, the new method also allows researchers to study background correlations

This new method of screening parental relationships from ancient DNA provides researchers with a versatile new tool
.
Looking to the future, the field of ancient DNA is developing rapidly, and more and more ancient genomes are produced every year
