Question

A. character viii B. character iv C. character v D. character vii

Using same diagram.....
Suppose that all of the species in the above example are plants, and that ? unlike their common ancestor ? species C, D, E and F inhabit alpine environments. A number of adaptations have been identified in this group of plants: species C, D, E and F share a character state that involves delayed flowering time (character state 5 for character iii), but species E and F have an additional physiological adaptation that allows them to metabolize rapidly at low temperatures (character state 1 for character ii). Assuming phylogeny 1 is correct, which of those two adaptations evolved first? Answer A. delayed flowering time (character state 5 for character iii) B. the physiological adaptation (character state 1 for character ii) C. they evolved at the same time because they both involve adaptations to the same environmental conditions D. the relative timing cannot be determined with the information and phylogeny provided

Explanation / Answer

C. they evolved at the same time because they both involve adaptations to the same environmental conditions
