Many species of multicellular organisms differ greatly from each ... not the unicellular one might have been important for the evolution of multicellularity. That is, certain "special" genes ...

For most of human history, the overall population is believed to have remained quite low. But since the early 1800s, the ...

Animals, however, evolved from single egg cells into multicellular organisms, a process involving ... perkinsii, prompting a fresh look at the evolution of life’s complexity.
