Despite the importance of these forces, their role in the evolution of development is still not well understood. Animal embryos undergo tissue flows and folding processes, involving mechanical forces, ...

Small fold – big role: A tissue fold known as the cephalic furrow, an evolutionary novelty that forms between the head and the trunk of fly embryos, plays a mechanical role in stabilizing embryonic ...

Two species of worms have retained remarkably similar patterns in the way they switch their genes on and off despite having split from a common ancestor 20 million years ago, a new study finds. The ...
