The English moth, Biston betularia, is often cited as an example of observed evolution. There are two colors of this moth, light and dark (typica and carbonaria). Kettlewell found that dark moths constituted less than 2% of the population prior to 1848. Then, the
frequency of the dark coloration began to increase. By 1898, the 95% of the moths in Manchester and other highly industrialized
areas were of the dark color. Using the moth example, analyze the events in order to identify support for the statement: natural
selection changes populations, not individuals. Choose ALL that apply.
A)
Variation in the population existed.
B)
Color variation is a result of different gene combinations.
C)
In response to environmental change, moth coloration changed from light
to dark.
D)
Due to natural selection, the ratio of different genetic combinations is
changing
E)
Predator pressure resulted in the light colored genotype being removed
from the gene pool.

The accompanying figure shows the percent of selected dna sequences that match between a chimpanzee and other primates. these data support the hypothesis that the figure shows the percentage of selected d n a sequences that match between the chimpanzee and other primates. the human has an almost 98 percent match, the gorilla has an almost 97 percent match, the orangutan has a 96 percent match, the gibbon has an almost 95 percent match, and the old world monkey has an almost 92 percent match. the accompanying figure shows the percent of selected dna sequences that match between a chimpanzee and other primates. these data support the hypothesis that the figure shows the percentage of selected d n a sequences that match between the chimpanzee and other primates. the human has an almost 98 percent match, the gorilla has an almost 97 percent match, the orangutan has a 96 percent match, the gibbon has an almost 95 percent match, and the old world monkey has an almost 92 percent match. chimpanzees and gibbons are the most closely related the chimpanzee's closest surviving relative is humans orangutans are the primates least closely related to chimpanzees old world monkeys and gibbons are the most closely related
