Evolution of marine mammals to water converges in some genes
By Ruth SoRelle, M.P.H. When marine mammals such as whales, dolphins, manatees and walruses moved from land to water, a series of physical abilities –– limbs adapted for swimming, less dense bones that make them more buoyant and a large store of oxygen relative to their body size – made it possible. Yet these animals … Continue reading
