It is more closely related to the mammoth than it is to the West African manatee. (1) It is more closely related to the West Indian manatee than it is to the mastodon. (2) It is not related to the Brazilian manatee or the mammoth. (3) It is the ancestor of Steller’s sea cow. (4) According to some scientists, patterns of evolution can be illustrated by the diagrams below. 10. Which statement best explains the patterns seen in these diagrams? The organisms at the end of each branch can be found in the environment today. (1) organisms that are living today have all evolved at the same rate and have undergone (2)The the same kinds of changes. involves changes that give rise to a variety of organisms, some of which (3)Evolution continue to change through time while others die out. These patterns cannot be used to illustrate the evolution of extinct organisms. (4) Which statement best illustrates a rapid biological adaptation that has actually occurred? 11. Pesticide-resistant insects have developed in certain environments. (1) Scientific evidence indicates that dinosaurs once lived on land. (2) Paving large areas of land has decreased habitats for certain organisms. (3) The characteristics of sharks have remained unchanged over a long period of time. (4) The diagram below illustrates the change that occurred in the physical appearance of a 13. rabbit population over a 10-year period. Which condition would explain this change over time? a decrease in the mutation rate of the rabbits with black fur (1) a decrease in the advantage of having white fur (2) an increase in the advantage of having white fur (3) an increase in the chromosome number of the rabbits with black fur (4) Which statement best describes a current understanding of natural selection? 58. (1)Natural selection influences the frequency of an adaptation in a population. (2)Natural selection has been discarded as an important concept in evolution. (3)Changes in gene frequencies due to natural selection have little effect on the evolution of species. (4)New mutations of genetic material are due to natural selection. 63. Which species is most likely to survive changing environmental conditions?
