Under nearly all circumstances, postzygotic reproductive
isolation cannot evolve under the direct action of natural
selection. Instead, postzygotic isolation evolves as a by-product
of other genetic changes as proto-species diverge. In contrast,
natural selection can directly act to enhance prezygotic
reproductive isolation. Consider two species with overlapping
ranges. If hybrids between the species are less fit than pure
species individuals, females that mated with heterospecific males
would be at a selective disadvantage, because their resulting
offspring had low fitness....

From the pages 571-587 attached below.
1a) Suppose a population of guppies was infected with a
parasite. In that population a mutation results in a parasite
resistant genotype that spreads through the population through
natural selection. A subsequent mutation in the parasite results in
a genotype that is unaffected by the newly evolved resistant guppy
genotype. What is the name of the hypothesis that explains this
host parasite “arms race”.?
1b) What is this name...
