How Cheese, Wheat and Alcohol Shaped Human Evolution

Over time, diet causes dramatic changes to our anatomy, immune systems and maybe skin color.

You aren’t what you eat, exactly. But over many generations, what we eat does shape our evolutionary path. “Diet,” says anthropologist John Hawks, of the University of Wisconsin-Madison, “has been a fundamental story throughout our evolutionary history. Over the last million years there have been changes in human anatomy, teeth and the skull, that we think are probably related to changes in diet.”

As our evolution continues, the crucial role of diet hasn’t gone away. Genetic studies show that humans are still evolving, with evidence of natural selection pressures on genes impacting everything from Alzheimer’s disease to skin color to menstruation age. And what we eat today will influence the direction we will take tomorrow.
