Why humans have a philtrum, the groove above your lip, explained by an evolutionary biologist — from embryonic face-building ...

Like all complex organisms, every human originates from a single cell that multiplies through countless cell divisions. Thousands of cells coordinate, move and exert mechanical forces on each other as ...

By tracking neural crest cells in catshark embryos, researchers discovered that the molecular toolkit behind face-building is surprisingly conserved across jawed vertebrates. The real differences ...

In mammals, hair follicles emerge during embryonic development, forming geometric patterns that vary from one species to ...

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 ...
