Nels and Vincent discuss the genome sequence of an ancient wooly mammoth, which shows that the three-dimensional architecture of the DNA can persist after 50,000 years.
Nels and Vincent explore a direct experimental test of Ohno’s Hypothesis, which states that gene duplication can help genes tolerate new mutations and thus facilitates the evolution of new phenotypes.
