Tomorrow we will talk about the consequences of potential gene-environment mismatch. It is thought that most of human evolution, and thus selection for human genes has occurred during the Pleistocene, an epoch that lasted from about 1 million years ago and ended 12 thousand years ago. Of course we live in a radically different environment now. Could there be a mismatch between genes shaped by selection in the Pleistocene environment now expressed in our modern environment?
