Evolution is based on which of the following concepts? (a) organisms share a common origin (b) over time, organisms have diverged from a common ancestor (c) an animal’s body parts can change over its lifetime, and these acquired changes are passed to the next generation (d) a and b (e) a, b, and c
Charles Darwin proposed that evolution could be explained by the differential reproductive success of organisms that resulted from their naturally occurring variation. Darwin called this process (a) coevolution (b) convergent evolution(c) natural selection (d) artificial selection (e) homoplasy
Darwin emphasized that evolution via natural selection leads only to
a) progress as defined by increasing heterogeneity.
b) higher and lower forms within the same species of organism.
c) the establishment of some societies that are more civilized than others.
d) increasing adaptation between organisms and their given environment.

- What was Darwin's original insight that led to his theory of evolution? A) Plants and animals can be modified by human-controlled selective breeding. B) Genes, which are passed along through eggs and sperm, can only provide some of the hereditary foundation for evolution. C) Breeding in nature is selective and can produce changes in living things over generations. D) Mutation in the 23rd chromosome is the ultimate source of all genetic variation.arrow_forwardWhen two organisms are very distantly related in an evolutionary sense, (a) they should have extremely similar embryonic development. (b) they must share a very recent common ancestor. (c) the sequences of DNA in their genes should be less similar (more different) than those of two more closely related organisms. (d) they should share more homologous traits than two more closely related organisms share.arrow_forwardIf two different organisms are closely related evolutionarily, then they will (a) be similar in size. (b) share a recent common ancestor. (c) have very different DNA sequences in their genes. (d) be randomly located throughout the world.arrow_forward
- Traits that are inherited and improve an individual’s ability to survive and reproduce are called traits. (a) adaptive (b) polymorphic (c) biological (d) sympatric (e) allopatricarrow_forwardUnlike natural selection, is not related to an individual’s ability to survive and may result in offspring that are less well adapted to survive in a particular environment. (a) genetic drift (b) sexual selection (c) directional selection (d) convergent evolutionarrow_forwardIn what way does the modern synthesis strengthen scientific understanding of evolution? (a) is based on the sequence of fossils in rock layers (b) uses genetics to explain the source of hereditary variation that is essentialto natural selection (c) was first proposed by ancient Greek scholars (d) considers the influence of the geographic distribution of organisms on their evolution (e) is reinforced by homologies that are explained by common descentarrow_forward
- DNA (a) is produced during cellular respiration (b) functions mainly to transmit information from one species to another (c) cannot be changed (d) is a good example of a biological system (e) makes up the genesarrow_forwardWhich key feature of living organisms is best described as the transmission of DNA from parent to offspring? A.)Homeostasis B.)Growth C.)Response to changes D.)Inheritancearrow_forwardIf natural selection can only operate on existing variants, where does all that variation come from? If, as Darwin (1868) and Huxley concluded, variation arose from changes in development, then how could the development of an embryo change when development is so finely tuned and complex?arrow_forward
- Which of the following is not true of natural selection?(a) natural selection acts to preserve favorable traits and eliminate unfavorable traits (b) the offspring of individuals that are better adapted to the environment will make up a larger proportion of the next generation (c) natural selection directs the course of evolution by preserving the traitsacquired during an individual’s lifetime (d) natural selection Test Your Understanding acts on a population’s genetic variability, which arisesthrough mutation (e) natural selection may result in changes in allele frequencies in a populationarrow_forwardAccording to Darwin’s model of evolution, evolution can only occur if there is some variation present among the individual members of a population. Which statement best describes the source of this variation among members of a species? A) individuals will vary depending on geography and climate B) variation exists because not all genes will be expressed C) variation among individuals may arise as a result of mutations in the genetic code D) variation exists because different individuals will have different access to food and other resourcesarrow_forwardUsing examples, explain how FIVE of the following support the modern theory of evolution. (i) homologous structures (ii) analogous structures (iii) vestigal structures (iv) fossil record (v) biogeography (vi) embryology (vii) molecular biologyarrow_forward
