The findings detailed in the article below are entirely predictable. By selectively killing (overfishing) the largest fish (and biggest animals) humans unintentionally guide the course of evolution to favor the small, quick reproducers. While human caused, this result […]

This is quite relevant because we have been discussing how grizzly bears are displacing polar bears in the Arctic. We already knew brown bears were polar bears’ ancestors.

Human fishing and hunting accelerating evolution of species. Fishing and hunting by humans is accelerating the speed of evolution in some species as it removes whole generations of large adults who would otherwise reproduce. By Richard Alleyne, Science Correspondent. UK Telegraph.
