Biologists have observed squirrels and salmon developing at an accelerated pace, causing them to reproduce at a younger age. Earlier summers have caused some flowers to bloom earlier in the year. And corals are forging new relationships with microscopic algae to survive in warmer, more acidic seas.

As the planet continues to warm, evolutionary changes are expected in other species as well — including Homo sapiens. Climate changewill alter the internal workings of our bodies in subtle but significant ways and will likely…
