Abstract

Gene flow in evolution Evolutionary theory has a lot to say on the way that natural populations adapt to their environment, and it is an important factor when considering the impact of human actions on evolutionary dynamics of populations. But experimental data to support the theory are scarce, and two groups this week report findings at odds with accepted thinking. It is commonly assumed that population divergence is a balance between the diversifying effect of selection and the homogenizing effect of gene flow caused by immigration and dispersal. But both of these experiments, on populations of the great tit Parus major, show that differential dispersal can maintain and even emphasize genetic differences.
