Of the following, which one is an example of an evolutionary explanation (as opposed to a functional explanation)?A. People evolved a fear of snakes because many snakes are dangerous.B. Humans have a (tiny) tailbone because our ancient monkey-like ancestors had a tail.C. People evolved an ability to recognize faces because that ability is essential for cooperative social behaviors.D. People evolved a tendency to form long-term male–female bonds because human infants benefit from the help of two parents during their long period of dependence.

- Several very distantly related species (e.g., bats, birds, insects) have evolved the capability of flight. The most recent common ancestor of insects and vertebrates likely lived over 500 million years ago and was flightless. This independent evolution of flight in multiple, distantly related taxa is an example of what evolutionary process/pattern? a. Evolutionary reversal b. Convergent evolution c. Speciation d. Synapomorphyarrow_forwardScientists compare the structures of a chicken embryo and a human embryo at the same stage of development. They find that both vertebrates have similar shapes and structures, including the presence of gill slits and tails. How is this comparison of the embryos used as supporting evidence of evolution? A. The similarities suggest that chickens and humans are the direct descendants of modern day fish with tails and gill slits. B. The similarities suggest that vertebrates passthrough each of the adult stages of their evoluntionary history as they develop. C. The similarities suggest that vertebrates can undergo genetic changes during development that lead to the evolution of new species D. The similarities suggest that chickens and humans descend from ancestors with genes that code for the development of tails and gill slitsarrow_forwardResearchers have found fossils of Eocene horse species in Colorado. Deeper deposits contain smaller species, and more recent deposits contain larger species. How does this observation support the theory of evolution? A. It provides evidence that species change over time. B. It does not support the theory of evolution. C. It shows that all species are related to each other. D. It proves that environments have changed over time. E. It suggests that species are unchanging and of recent origin.arrow_forward
- The bones in the front fins of whales and the bones in the human arm evolved from a common ancestor but carry out different functions. This is an example of A. homologous structures. B. vestigial structures. C. analogous structures. D. embryonic structures.arrow_forwardScientists believe that animals have a common ancestor because a. all animal appendages have been modified into limbs. b. all animal genes are very similar. c. all animals are autotrophs. d. all animals share unique features of the junctions between cells.arrow_forwardDespite not sharing a recent common reptilian ancestor, both mammals and birds are homeotherms. Which of the following statements best explains how this trait came about? A. The development of homeothermic capabilities is the result of convergent evolution due to similar selection pressures B. Similar development of homeothermic capabilities is the result of adaptive radiation from a reptilian ancestor C. Birds and mammals diverged from dinosaurs, which were homeothermic D. Mammals and birds both inherited homeothermic capabilities from an ancient reptilian ancestor and then diverged E. Similar homeothermic capabilities in birds and mammals can be explained through homologous structuresarrow_forward

Explain why.A. During its lifetime, an animal evolves to become better adaptedto its environment.B. The process of biological evolution has produced species thatare better adapted to their environments.C. When an animal is better adapted to its environment, the process of natural selection makes it more likely that the animalwill reproduce.arrow_forwardWhich of the following observations best supports the conclusion that two animal species evolved from a common ancestor in recent geological history? A The species are both herbivores. B The species have similar bone structure. C The species live in the same environment. D The species both obtain oxygen from the air. Choosearrow_forward
- Which of the following best reflects a phylogenetic relationship between chimpanzees and baboons? A. They are grouped together because they live in similar habitats. B. They are grouped together because they have a common ancestor in recent history. C. They are grouped together because they both have an opposable thumb. D. They are grouped together because they both feed their young breast milk.arrow_forwardWhich of the following statements is true? A. Evolution involves a change in gene frequencies from one generation to the next B. Natural selection is the only mechanism through which animals evolve to become adapted to their environment C. Genetic drift results in evolution but not adaptation to the environment D. For natural selection to occur, differences in genetically-based traits must result in differential reproductive success E. All of the above are true A blastopore... A. Is the opening through which food enters a gastrovascular cavity B. Is an opening to the water-filled central cavity of a sponge C. Is the opening to the primitive gut that gives rise to the mouth in a deuterostome eucoelomate D. Is the open end of the archenteron that appears during gastrulation E.
