One of the biggest quests in biology is understanding how every cell in an animal’s body carries an identical genome yet still gives rise to a kaleidoscope of different cell types and tissues. A ...

Animals, from worms and sponges to jellyfish and whales, contain anywhere from a few thousand to tens of trillions of nearly genetically identical cells. Depending on the organism, these cells arrange ...
