exist. 37. Allopatric speciation is probably the most common way that new species form. Please describe a hypothetical scenario in which an initial ancestral population could split to form a new species through allopatric speciation. A fully correct answer will at least incorporate the following terms: gene flow, divergence, natural selection (including sexual selection), genetic drift, and reproductive isolation. 38. How did an increased understanding of plate tectonics help biogeographers better understand the distribution of species? 39. How did Richard Bambach’s conclusions about changes in species diversity over time differ from David Raup’s conclusions? 40. Please discuss two factors that may trigger an adaptive radiation and provide an example of each. 41. Some people argue that climate change due to increasing carbon dioxide in the atmosphere is nothing to worry about because carbon dioxide levels, and temperatures, have always fluctuated throughout time. How would you respond to this argument? 42. Please discuss two abiotic factors that may have contributed to the profusion of animal diversity during the Cambrian.
