In suggesting alternative hypotheses to explain the figure above, your lab partner states that perhaps mosses didn't evolve until recently, which is why they increase after herbs and shrubs. Which of the following would be the best response to your lab partner?
A. If you look carefully at the graph, there were a few mosses present 300,000 years ago, so they probably arose then. B. The percent of moss species has actually been steadily increasing since 300,000 years ago as climates became drier. C. Mosses are bryophytes and resemble early plants, so increases in more recent years more likely indicate a shift in climate. D. Mosses are angiosperms, so they didn't become widespread until the climate was dry enough for pollen transfer. E. Mammoths probably ate the mosses, so they did not appear until after the mammoths went extinct.
