Biology Chapter 15 Test - Evolution

Sep 30, 2026

Biology Chapter 15 practice test: Evolution assesses core concepts of evolutionary theory and evidence. The exam includes true/false statements and multiple-choice questions covering natural selection, Darwin’s contributions, homologous and vestigial structures, biogeography, and genetic equilibrium under the Hardy-Weinberg principle. Students also apply selection models such as stabilizing, disruptive, and directional selection, interpret adaptations through camouflage and mimicry, and evaluate how fossils support evolutionary change.

Multiple Choice

ID:A Date: Name: # Biology Chapter 15 Test:Evolution True/False Indicate whether the statement is true or false. 1.A vestigial structure in one organism can be defined as a reduced form of a functional structure in anotherorganism. 2.Natural selection is based on the concepts of excess reproduction,variation,inheritance,and the advantagesof certain traits. 3.Darwin developed his theory of evolution exclusively from his work on the Galapagos Islands. 4.According to Darwin,the process of natural selection could result in a new kingdom of organisms. 5.Fossils,although interesting,do not actually provide evidence of evolution. 6.Homologous structures indicate a shared ancestry,while vestigial structures do not 7.Biochemical traits helped Darwin unravel his theory of evolution. 8.Biogeography is the study of why certain species live in certain areas. 9.The Hardy-Weinberg principle describes the conditions within which evolution definitely occurs. # Multiple Choice Identify the choice that best completes the statement or answers the question. 10.Which answer best shows an animal's adaptation to the tropical rain forest? a.camouflage in a tree frog b.the long neck of a giraffe c.an elephant's long trunk d.migration of birds in winter 11.Which combination of characteristics in a population would provide the greatest potential for evolutionarychange? a.small population,few mutations b.small population,many mutations c.large population,few mutations d.large population,many mutations 12.When investigating shell color of a species of snail found only in a remote area seldom visited by humans,scientists discovered the distribution of individuals that is shown in the graph in Figure 15-1.Based on theinformation shown in the graph,what form of selection is the snail population undergoing?

Derived traits result from artificial selection;ancestral traits result from natural selection. b.Derived traits appear in species;ancestral traits appear in genera or higher taxa. c.Derived traits are primitive;ancestral traits are contemporary. d.Derived traits are recent features;ancestral traits are more primitive features. 18.Which of the following is the explanation of why bird wings and reptile forelegs are evidence of evolution? a.Similar functions point to a common ancestor. b.Analogous structures indicate a common ancestor. c.Vestigial structures point to a common ancestor. d.Homologous structures indicate a common ancestor. 19.Superficially similar features molded by natural selection in very different species are classified as what kindof structures? a.vestigialc.analogous b.homologousd.comparative

FAQs

What does the test focus on in Evolution (Chapter 15)?

It focuses on core ideas of evolution, including natural selection, evidence from fossils and structures, biogeography, genetic equilibrium, and types of selection and adaptation.

How does the test ask students to demonstrate understanding?

It uses both true/false items and multiple-choice questions that require identifying correct statements, mechanisms, and types of selection or adaptation.

What topics related to evidence of evolution are included?

The test includes questions about how fossils provide evidence, how homologous and vestigial structures relate to shared ancestry, and how biochemical traits can support evolutionary explanations.
