Her aim is to show that natural selection and drift are causes of evolutionary change. Millstein and (following her) Stephens make a distinction between driftas-process and drift-as-product (or outcome).5 Let us say for present purposes that evolution is a longterm change in gene frequencies in a population.6 For Millstein and Stephens, drift-as-product is the culmination (4) Variation with respect to trait T caused evolutionary change in population P. test to check whether natural selection causes evolutionary change, we (5*) Natural selection caused evolutionary change in population P. (5*) Natural selection caused evolutionary change in population P. Selection and drift are distinct processes whose magnitude gets measured by different population parameters (fitness on the one hand, If you think that natural selection is a force that mediates differences of heritable fitness, then you	./cache/work_e7xmdd57mna2bjubrglel3sok4.pdf	./txt/work_e7xmdd57mna2bjubrglel3sok4.txt
