    GEN continues its celebration of the “Year of Darwin” by looking at new research that provides important and novel insights on the evolution of genes.

    Scientists at the University of Leeds in the U.K. and the Genome Institute of Singapore say they have discovered one of the mechanisms governing how our physical features and behavioral traits have evolved over the centuries. Darwin proposed that such traits are passed from parent to offspring, with natural selection favoring those that provide the greatest advantage for survival. But he did not have a scientific explanation for this process.

    The investigators report that a protein known as REST plays a central role in switching specific genes on and off, thereby determining how specific traits develop in offspring. To learn more about the significance of this finding, GEN interviewed lead researcher Ian Wood, Ph.D., a senior lecturer and a member of the University of Leeds’ faculty of biological sciences. He works in the university’s Institute of Membrane and Systems Biology.
