“The individuals of the population all exist in a relatively small locus in gene space, as a cloud of data points---obviously, with a barycenter.”
“Think of a "population barycenter", where different parts of the population system individuals have unequal survival differentials, even if only very slight.”
“As the generations pass by, it is rather obvious that the barycenter will drift in a nonrandom direction if the differentials are not "symmetric" around it.”
“Secondly, imagine them not simply floating semi-idly but rather orbiting an apparent barycenter, like an underwater solar system of satellite hatcheries revolving around a feeder sphere from which nutrients ooze out and are fling outwards towards awaiting hungry fishes.”
