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.
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.
Nels and Vincent reveal how a motor protein in corn causes preferential transmission of chromosomes to egg cells, leading to non-Mendelian inheritance
Nels and Vincent discuss the evolution of blood feeding to nonbiting in a mosquito, and evolution of bacterial virulence in the house finch caused by incomplete host immunity.
