Watch the Ted Talk "How Our Microbes Make Us Who We Are".
This is a talk given by Dr. Rob Knight of UC San Diego. He is a researcher and co-founder of both the American Gut Project and the Earth Microbiome Project. (In case you are wondering about the accent, he is originally from New Zealand).
As you watch the video, answer the following questions. Note: You must use your own words in answering!

1) Knight's lab identified the microbes present on the bodies of 250 healthy volunteers and then used that information to make a "map" of the human microbiome.
a. What does each point (dot) on the map represent?
b. What do the four colors ("continents") of the map represent?
2) Each individual point (dot) on each "continent" do not exactly line up. What does this tell you about microbial communities on people?
3) Knight says that while adult microbial communities are relatively stable, infant microbial communities develop over time and begin differently depending upon how the child is born.
a. How are gut microbes different in a child that is born vaginally compared to a child born by Cesarean?
b. What does Dr. Knight say could be negatives of Cesarean birth?
4) What changes occur in the fecal microbial community of a naturally-born infant who is given antibiotics?
5) What does the current research say is a more accurate predictor of obesity, the type of gut microbes in a person or the person's own human genes?
6) What does this imply about the human microbiome?
7) What is the effect of fecal transplantation in patients suffering from difficile diarrhea?
