Great whites 'not evolved from megashark'

[Still Waters]

A new fossil discovery has helped quell 150 years of debate over the origin of great white sharks.

Carcharodon hubbelli, which has been described by US scientists, shows intermediate features between the present-day predators and smaller, prehistoric mako sharks.

The find supports the theory that great white sharks did not evolve from huge megatooth sharks.
