How do cells know what they should become as the body develops? Biological development depends crucially on spatial patterns: the lines that eventually give rise to segments, organs, or markings like ...

Competition between species played a major role in the rise and fall of hominins – and produced a “bizarre” evolutionary pattern for the Homo lineage – according to a new University of Cambridge study ...

In most vertebrates, skin appendages such as hair, feathers, or scales originate from placodes—small, specialized skin regions whose spatial organization is controlled by well-conserved genetic ...
