Biologist marking the location of traps for Red squirrel ; Character: Caroline Trudeau
Canadian biologists are studying the red squirrels in the Yukon since 1987. They recently discovered that they could adapt to global warming, not only by physical and adjustments in behavior, but also by genetic change.
This astonishing discovery is consistent with the theory of evolution which holds that living organisms adapt changes in their environment through natural selection.
