QUESTION 7 Darwin's concept of natural selection demonstrates that fitness: varies with the situation (is different in each habitat) remains constant for all types of environments, or even with changing environments is the level of physical strength of the species is the level of physical endurance of the species all of the above QUESTION 8 When the instructor discussed speciation (how new species evolve out of existing species), he pointed out that most species are polytypic (made up of several types, known as subspecies). In a polytypic species, these subspecies: can still successfully reproduce with each other in the wild cannot successfully reproduce with each other in the wild is generally identical in genotype (genetic makeup) is generally still identical in phenotypes (physical structure) has phenotypes which produce their genotypes QUESTION 9 When speciation takes place within a species (such as when the variation between subspecies becomes so great that we can no longer classify then as belonging to the same species), the diverging or separating groups: can still successfully reproduce with each other in the wild cannot successfully reproduce with one another (that is, they cannot produce a live, fertile offspring) is generally still identical in genotypes (genetic makeup) is generally still identical in phenotypes (physical structure) none of the above describe what occurs in speciation
