A genomic march of the penguins
It’s undeniable that penguins are a marine representative of the charismatic megafauna group. I have an affinity for stuff we need microscopes to see, BUT I agree that penguins are cute (just LOOK at these National Geographic photos…they’re even in … Continue reading

Genomic signatures of ancient rendezvous and separation in elephant evolution
Evidence from various levels of the tree of life is showing that we’ve been picturing ancient encounters between related species all wrong and admixture events are probably more common than expected. Even rendezvous among primates, caniforms, and majestic proboscideans often … Continue reading

Different ways to have sex, yet still be a weed
Baker (1955) noticed that when mates are lacking, the ability to undergo self-fertilization will greatly enhance colonization success. Uniparental reproduction seems to be common in colonizing species, whether it’s from a continent to an oceanic island, during a biological invasion or during range … Continue reading
