An
article in the New York Times written by Gretchen Reynolds discusses an experiment done by the
University of Missouri in Columbia that interbred rats and separated them into two groups: one who is very active and one who is very lazy. Next, the DNA of the groups were looked at to see if their levels of activity were due to genetics. In previous studies, it is shown that relatives had similar exercise patterns. This was especially true in twins, whether they lived together or not. After looking at the two groups, they found that the lazy group was slightly heavier, but that physically they were very similar. Next, the emotion toward exercise was thought to impact the outcome. This is where they felt genetics would come into play. After looking at the rats genes, they found many differences between group one and group two.
