Which of the following is the most defensible stațement to make about the role of
haplodiploidy in the evolution of sterile castes?
sterile castes presumably would not have evolved in the hymenoptera in the
absence of haplodiploidy.
owing to the prevalence of multiple mating in social hymenoptera colonies,
haplodiploidy has probably had a negligible effect on the evolution of sterile
castes.
haplodiploidy is the primary factor responsible for sterile castes in ants, wasps
and termites.
haplodiploidy was not an absolute requirement for the evolution of sterile castes
in social insects.
The biological species concept depends on the existence of barriers to reproduction. What are they? Does this species concept apply in all situations? Think of an example from nature where the biological species concept would NOT be that applicable. Which species concept would be better in this example?
How does speciation occur? What environmental factors might contribute to speciation? Can an individual speciate? Use terminology for the two kinds of speciation we have learned about.
What is “gene flow”? What does it mean if there is NO gene flow?
Two groups of individuals are separated by either side of a canyon. One researcher found that they do not cross the canyon at any point. The group on the north side have fluffy tails and thicker coats, and they do not eat moss. The south side individuals eat moss almost exclusively, have a thin coat and tail, but otherwise are generally identical. When in the lab they mated successfully, and the offspring of that mating also mated…
Three-spined sticklebacks that have colonized freshwater streams and lakes have repeatedly evolved into similar forms. The pattern can be seen in hundreds of freshwater bodies around the world. Can a single biological species arise more than once (i.e., polyphyletically)? How might this possibility depend on the nature of the reproductive barrier between such a species and its closest relative?

The following questions could help answer the question above. What are the advantages of sexual reproduction? What are the disadvantages? How do traits selected by sexual selection and those selected by differential survival mix in an animal species? i.e. is it more important to mate or survive? Use specific examples to illustrate your point. Your answers should indicate an understanding of the mechanism behind natural selection.
