These primitive jawless fish could hold clues to the evolutionary origin of vertebrate heads, as evidenced by detailed embryological analyses. The origin of the vertebrate skull is a topic of much ...

How are the body’s segments formed? The body of a vertebrate organism consists of segmented axes, which is most distinct in the skeleton. The process of somitogenesis is key to the development of ...

Vertebrates have a pretty diverse array of body plans, and one of the reasons for this is some evolutionary flexibility in the length of their primary body axis, the one that runs from head to tail.

Somitogenesis is the process by which somites are formed during embryogenesis. Somitomeres are formed first, which are essentially segmented blocks of tissue that differentiate to form the skeletal ...

Researchers used iPS cells to reconstructed the human 'segmentation clock,' a key point in early embryonic development that determines how the body gets segmented. The 'segmentation clock' is a ...

A genetic mutation commonly found in cancer patients may also affect how the human body develops in the womb, according to new research from the University of Dundee. Science X Daily and the Weekly ...

Scientists have investigated lamprey embryos using cutting-edge microscopic techniques to reveal interesting insights about vertebrate head evolution, clarifying an unresolved mystery in basic science ...
