Nocturnal and diurnal mammals see the same—but only for a brief time. When mice are born, the chromatin in the cells of their eyes has a diurnal structure. Day by day, the layout of this chromatin slowly inverts, allowing ...

Of the three billion base pairs in the human genome, less than two percent contain the information encoding the ~20,000 proteins. That is, because at least half of our genetic material originated from selfish genetic elements ...
