Nels and Vincent explore the evolution of new protein-coding genes de novo from nocoding DNA sequences, using the antifreeze protein of northern codfish as a model.
Nels and Vincent move back to reproductive isolation – this time, pre-zygotic, in the charismatic orchid bee where the males make chemically distinct perfumes to attract mates of the same species.
Nels and Vincent look at the intracellular bacteria Legionella from an evolutionary perspective: the role of gene acquisition and reshuffling from plants, animals, fungi, and archaea in the emergence of human pathogens.
Nels and Vincent reveal a highly conserved protein that acts as an evolvability factor, increasing mutation and the ability of bacteria to become resistant to antibiotics.
David Quammen joins Nels and Vincent to talk about his new book, A Tangled Tree, including evolutionary trees, Carl Woese, Lynn Margulis, horizontal gene transfer, and much more.
Mia joins Nels and Vincent to unravel their finding that the transposons that maintain the ends of chromosomes in Drosophila have evolved in conflict with the genome.
Nels and Vincent reveal that female-specific DNA associated with sex in strawberries has repeatedly changed its genomic location, possibly linking new genes with sex.
Nels and Vincent discuss how the loss of an enzyme in marine mammals millions of years ago now makes them at risk for neurotoxicity caused by human-made organophosphorous pesticides.
Nels and Vincent are astounded by the finding of an insect-derived virus in a fungus that manipulates the behavior of flies.
Matt joins Nels and Vincent to discuss the neutral theory of evolution and its rejection in light of genome-scale data.
