Marine mammals and the legacy of gene loss: evolutionary biology informs policy

Life began in the water.  Microbes swarmed around in primordial ooze, banded together to form multicellular organisms, and eventually grew complex enough to leave their watery homes and become the terrestrial animals that exist today.  Some of those land-dwelling creatures became mammals, and in a surprising twist, three separate lineages of ancient mammals then returned … Continue reading Marine mammals and the legacy of gene loss: evolutionary biology informs policy

Bird Genomes: Winging our way

Recently, 40+ bird genomes were sequenced, and we are still just beginning to sift through the data. How did birds lose their teeth? (Yes, teeth.) How did they evolve to learn complex songs? Has flying made their genomes smaller? Get the scoop from Allison Schultz.
