Over time, some organisms have co-evolved so they mutually benefit and depend upon one another. Many plants, for example, have d
eveloped adaptations in order to attract specific animals that can spread their pollen or seeds and ensure the plant's reproductive success. Which of the following is an example of this type of co-evolution? A. A flower develops a musty odor and only opens at night to attract nocturnal bats with a similar odor. B. A flower develops a yellow and blue color, so it can be seen by bees which are attracted to these colors. C. A flower develops a large, flat surface to attract butterflies that prefer to perch as they feed. D. all of these
This is referred to as co-evolution. It involves the reciprocal evolution of 2 species. This kind of evolution can be seen in mutualism (like the choices described above), and also predator-prey, host-parasite relationships. The term co-evolution was coined by Paul R. Ehrlich and Peter H. Raven in 1964.
