Embryonic development is one of the most dynamic biological processes in nature. Cells and tissues organize and reorganize ...

Is there only one optimal configuration an organism can reach during evolution? Is there a single formula that describes the trajectory towards the optimum? And can we 'derive' it in a purely ...

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 ...

In the earliest hours after fertilization, an embryo takes its first steps toward becoming a living organism by shedding maternal control and activating its own genetic program. This critical process, ...

Add Yahoo as a preferred source to see more of our stories on Google. As an evolutionary biologist whose career has focused on how embryos develop in a wide variety of species over the course of ...

Have you ever looked at a human embryo and thought, “That kind of looks like a fish”? If you haven’t, you might be surprised to learn that, in a way, we all begin our lives like this. The idea that ...

The distinct aging rates of neural progenitor cells and Wnt signaling dictate mammalian cortical layer proportions.

Summary: A father’s psychological stress prior to conception can actively alter his offspring’s physical growth via small molecular signals carried in sperm. The research demonstrates that prolonged ...
