Stone-Age Nuclear family Unearthed

In central Germany, scientists discovered a 4,600 year old grave. This grave is the earliest evidence of people living together as a family and also the oldest authentic molecular genetic evidence so far.DNA analysis showed the relationship between the man, woman, and two youngsters found in the small grave to be similar thus making them a family. Researchers hypothesized the family's death by concluding it as a violent attack. They stated that the skeletons had head injuries and injured vertebrae. Some had forearm and hand injuries (which researchers believed were from trying to protect themselves from the invaders.) Scientists also looked at at the strontium levels in teeth which builds up during childhood stages which could also help tell where the bodies were raised. They found out that women grew up in different areas then the men and children, which led the scientists to believe that they had marriage between different groups.
