Tracing Our Ancestors

Rick Kittles was an engaging speaker that spoke eloquently to his audience. Abet slightly fast pace, Kittles covered many concepts and ideas in a 45 minute span. Mutations, DNA analysis, and gene categorizing were all discussed early on. The core of his presentation revolved around theory in which where humanity has derive from – Africa. This eventually led his analysis of how DNA would be able to help trace ancestry through lack of gene differences verses gene similarity.

Tracing Our Ancestors was a bit disappointing. As a student of honors/AP biology, almost all information presented were already lectured and inform during class time. Kittles, though highly educated, had chose to lecture to a general audience (this make sense since most attendees were older, imply they are not up with the science times). The theory itself was interesting as it expanded on how DNA analysis was used, but in general the presentation felt like a review. An interesting information learn though was that skin color is a not a strong indicator of race. And though this can be derived though common sense, Kittles explained that the polygenic inheritance pattern would only showcase more of the dominate gene and ignore any other mixed race meant to be indicated. In general, the presentation, I felt was a bit dry. And though the topic was interesting, the information was a review. I wish Kittles elaborated more to cater to a more advance audience.
