The Human Family Tree was an enlightening documentary that described the way in which every human being is connected to one another in some way. Because humanity is based in genetics, these genetics had to begin from a smaller source or group. As individuals migrated to new areas, it is no wonder that they shared some of the same genetic materials.
New York City is a place where people have come from all different backgrounds making it the perfect place to sample people’s genetic backgrounds. In the context of one street, there are people from many different places, Bangladesh, the U.S., Asia and many others. And, these individuals are interested in learning more about their own backgrounds as evidenced by so many people waiting in line to participate.

The information gathered from check swabs on the street was then compared with other information such as climate maps to determine where people came from and why they left in the first place. One example was a woman from Africa that prompted a discussion of the earliest movements in Africa. Moving from a hunter gatherer background into more distinctive backgrounds was largely a result of location. As people mated over time, their genetic material became more and more distinct and isolated groups such as the Saan people in Africa had divergent material from those people that moved due to climate changes.
Scientists proposed that human beings migrated from places other than Africa in a similar manner, slowly over time. While much is known about this, studying history is always complicated by natural phenomenon such as volcano explosions, floods, tsunamis and ice ages. Thus, one of the most surprising parts of the video was the variety of angles from which this issue should be viewed. Historians, scientists and archeologists all play an essential role in determining the human family tree.
