Humans and sea stars have something in common – here’s why it matters to scientists studying organ development.

A new genetic screening method allows researchers to efficiently modulate individual genes across entire tissues and provides new insights into human development.

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

We have identified the gene that, when activated, initiates the developmental programme that results in cells forming a human body ...

For decades, biologists thought that early tetrapods, ancient vertebrates that started conquering the land over 300 million years ago, developed like modern amphibians—beginning their lives as purely ...

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 ...

The scientists behind the synthetic egg say it’s a crucial step to the de-extinction of species like the giant moa and the dodo. Colossal Biosciences announced that it successfully hatched 26 chickens ...
