Traffic Patterns Lab

Location: Mercer Village-Barnes & Noble Bookstore

Elapsed Time: 10 minutes

Almost 75% of the vehicles that drove by consisted of one driver and no passengers. Over 50% of the vehicles were classified as "small" vehicles, and 75% of drivers were not multitasking.

If a rate of 76 vehicles every 10 minutes continued for an entire hour, 456 vehicles would pass by Mercer Village in an hour. Tables 1-3 below display the values recorded during lab.

Mitochondrial Eve and the Diversity of Mankind

Science suggests that there is a maternal ancestor of all human beings. She is referred to as mitochondrial Eve (mtEve). All humans get their mitochondrial DNA from their mother. Genetics suggests that 99.9% of each humans mitochondrial DNA is the same. Knowing this allows for scientists to trace back to where they think mtEve originated. The picture below is a geographic depiction of this idea. According to this image she was most likely from Northeastern Africa.




This idea is amazing considering the diversity of the human population. 5 different peoples are identified below from across the world as an example of this diversity.
