Nels and Vincent look at how plant prickles, sharp epidermal projections that provide defense from predators and other advantages, arose by convergent evolution, the emergence of analogous traits in distantly related species. Hosts: Nels Elde and…
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.
