dynamics and therefore evolution?
6. How do the stabilizing, directional, and disruptive forces affect population stability?
7. What are the three current ideas or modes used to explain population evolution and
how does each support the extant and extinct evolutionary population data?
8. What are the definitions of a specie and macro-evolution?
9. How do the various Pre-zygotic and Post-zygotic barriers help species differentiate?
10. What are the major trends in macroevolution?
11. What are the modes of speciation and what forces (natural and man-made) can force
a specie into extinction?
