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
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.
Phil Grayson explains how improvements in mitochondrial and nuclear genomics have rewritten what seemed like an open-and-shut case in the evolution of flightless birds.
