TWiEVO 40: Eau de bee

  • February 15, 2019
  • Tagged as: courtship display, evolution, natural selection, odorant receptor, olfactory receptor, orchid bee, reproductive isolation, speciation, species identity

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.

TWiEVO 39: In a Legionella of their own

  • January 26, 2019
  • Tagged as: amoeba, DOT/ICM, effector proteins, evolution, evolve, horizontal gene transfer, host range, intracellular bacteria, Legionella

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.

TWiEVO 36: All’s not quiet on the telomeric front

  • October 24, 2018
  • Tagged as: chromosome, evolution, genome conflict, integrates, jockey, non-LTR retrotransposon, recombination, telomerase, telomere, transposable element

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.
