Archeologists have been studying four multiple-burial sites in Germany that are about 4,600 years old.

What is significant about this is that DNA from the bones is being used to determine what, if any relationship, there was between the people who were buried together. Scientists were able to determine that in one of the four graves, the people buried were a man, a woman, and two biological children of the couple. The positioning of the skeletons appears to be deliberate.

I always love getting a peak into the past like this. With today's ability to use DNA it truly brings history alive.

Nice find Alfredo.
