Scientists have discovered that both bony and cartilaginous fish develop their appendages via a shared mechanism -- the mechanism is also observed in land-dwelling vertebrates such as mice. They found ...
A collaborative team of scientists recently found that there is no physiological evidence supporting a leading theory -- which involves the surface area of fish gills -- as to why many fish species ...
The development of limb muscle has been well studied in most land dwelling vertebrates such as humans and modern research models. In these species, muscle precursors, or cells that will form limb ...
