The king snake is non-poisonous, but closely resembles the extremely poisonous coral snake. Studies using artificial snakes have demonstrated that the king snake is attacked by mammalian predators less often in areas where the coral snake lives. The coloration in the king snake represents an example of ____________.
Effect of Evolution

Incorrect. Carefully read the definition of each option. Think about what environmental factor, living or non-living, is most likely to influence the coloration pattern in the king snake. Try again.
camouflage, in which characteristics in a living species that resemble an inanimate object spread through the population over many generations because these traits enhance survival and reproduction of the species in that environment

coevolution, in which characteristics of one species select for characteristics in another species over many generations, enhancing survival and reproduction in both species
Question 1 of 3
mimicry, in which characteristics of one living species select for characteristics in another living species over many generations because these traits enhance survival and reproduction of the mimic
Correct. Mimicry is seen in a variety of organisms, including the Monarch and Viking butterflies. Can you discover other examples of mimicry?
Incorrect. Carefully read the definition of each option. Think about what might happen to hummingbird beak length over time if the host flower population were to undergo an evolutionary change from a long flower base to a much shorter one. Try again.
The tip of a hummingbird’s beak is the perfect length to drink nectar from the flower shown, enhancing the bird’s ability to obtain nutrients and increasing the flowers’ cross-pollination rate as the bird drinks from several different flowers in a region. The hummingbird and its flower represent an example of _________.
Correct. Many species, such as the hummingbird and its host plant, have co-evolved in mutually beneficial ways. Alternatively, parasites co-evolve with their hosts, as demonstrated by increasing frequency of adaptive traits that only benefit the parasite. Can you think of specific examples of parasite-host coevolution?

Question 3 of 3
Incorrect. Carefully read the definition of each option. Think about what environmental factor, living or non-living, is most likely to influence the coloration pattern in the butterfly. Try again.
Correct. Camouflage is seen in a variety of organisms, including butterflies, frogs, and even some mammals! Can you identify examples of other organisms adapting to hide from predators by using their natural habitat?
Butterflies in the genus Kallima look similar to a dead leaf, the common ground cover object in the butterfly’s natural habitat. The coloration in Kallima butterflies represents an example of ____________.
In each situation, a particular set of physical traits were favored by environmental selection. Mimicry, camouflage, and coevolution are not accomplished through conscious decisions by individual organisms. The unique traits have spread through the population over several generations by increased survival and reproduction of individuals who were most suited to the environment. When the environmental selection is strong enough, a particular form of the trait may become the only version left in all individuals of a population.
