Technology can Tell us About our Ancestors– By: Nithya N.

Scientists have sequenced the DNA from four frozen hairs of a Greenlander who died 4,000 years ago. DNA has a special sequence. Scientists have put the DNA from the Greenlander’s hair in their sequence.  The fact that they were able to do this means that genetic technology has improved a lot. The scientists found evidence proved that the man (nicknamed Inuk) was not even from Greenland but originated from Siberia. Researchers said that this provided evidence that people migrated from Siberia into the Americas about 5,500 years ago. They say that these findings can help transform the study of archeology and answer questions about the origins of modern populations and disease. Studies like this might be able to tell us what our ancestors looked like. For example, the DNA from the four frozen hairs has already given scientists hints about his appearance. They say that he had brown eyes, brown skin, and that he had shovel-form front teeth. They also presume that he died young because they found a lot of his hair. Scientists also know that the man lived among the Saqqaq people, the earliest known culture in southern Greenland that lasted from around 2500 BC to 800 BC. Scientist found Inuk’s hairs in a frozen Saqqaq site. “We have an increasingly powerful forensic tool with which to ‘reconstruct’ extinct humans and the demographics of populations,” two researchers said.

Discussion Questions:

1) How do you think that this can help us?

2) Can you come up with any other ways that this technology can be used?

  1. Wow! That would be amazing to find out what our ancestors looked like 4,000 years ago! But, how the scientists used modern day info to preform this task if fantastic. Also grweat job on this article. It was very interesting!
