Humans do not have tails, but do we have “what it takes” for a tail? Hens don’t have teeth, but they have the genes for it. With atavism, it is as if our genomes serve as archives of our evolutionary ...

By tracking neural crest cells in catshark embryos, researchers discovered that the molecular toolkit behind face-building is ...

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

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, ...

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

A discovery upends decades of assumptions regarding DNA replication. The study show that DNA replication in early embryos is different from what past research has taught, and includes a period of ...

Scientists very rarely get access to most sharks, the development of their young or the nursery grounds where they grow. So seeing a hammerhead shark (Sphyrna tiburo) embryo, halfway through its ...

Metabolism does more than fuel embryos—it sets their developmental rhythm. EMBL researchers found that a sugar molecule, FBP, controls the pace of spine formation, suggesting metabolism may act as a ...
