Thus, even though the spatial scale was so small, the forces of selection ecologi fundamentos de ecologia begon outweigh the mixing forces of hybridization — but it is a moot point whether we should describe this as a small-scale series of local fundamrntos or a polymorphic population maintained by a gradient of selection.

Again, there was transient polymorphism — but this time while populations were en route in the other direction. It feeds on advances in our knowledge of biochemistry, behavior, fundamentos de ecologia begon, plate tectonics and so on, but it feeds back to our understanding of vast areas of biology too. In the examples that we have used earlier in this chapter we know that melanic and normal peppered moths can mate and that the offspring are fundamentos de fundzmentos begon fertile; this is also true fundametnos plants from the different types of Agrostis.
