Fun Fact
Webbed fingers: Human embryos have webbed hands until ancient self-destruction genes tell those specific cells to die, carving out our individual fingers.
Glossary
cadherin (noun)
Any of a class of transmembrane proteins that play a key role in cell-to-cell adhesion. These proteins evolved over 600 million years ago, allowing single-celled ancestors to adhere and form animal tissues.
