Evidence For Evolution Practice

What is the term for the study of fossils and their role in understanding evolution?

• Paleontology

• Archaeology

• Anthropology

• Geology

What is 'embryonic development' and its relevance to evolution?

• The study of how embryos develop, showing similarities that suggest common ancestry.

• A process that only occurs in mammals during gestation.

• An unrelated phenomenon that has no impact on evolutionary theory.

• A method of cloning organisms for research purposes.

How do fossils provide evidence for evolution?

• They show changes in species over time and the existence of now-extinct species.

• They are used to date rocks and determine the age of the Earth.

• They provide information about the diet of ancient organisms.

• They are the remains of living organisms that have not changed over time.

What does the observation of similar embryos in different organisms suggest?

• The organisms share a common ancestry.

• The organisms have evolved independently.

• The organisms are all mammals.

• The organisms are all aquatic species.

What evidence supports the theory of evolution through comparative anatomy?

• Similar structures in different species indicate a common ancestor.

• Different species have completely unrelated anatomical structures.

• All species have identical anatomical structures.

• Anatomical structures are only similar due to environmental factors.

What does the term 'adaptive radiation' refer to?

• The process by which organisms diversify rapidly into a variety of forms to adapt to different environments.

• A method of genetic engineering used to create new species.

• The phenomenon where species become extinct due to environmental changes.

• A type of radiation therapy used in medical treatments.

True or False: Organisms with similar amino acid sequences have a more recent common ancestor than those with dissimilar sequences.

• True

• False

• It depends on the environment

• Only for certain species

What field of study examines the similarities in development between different organisms?

• Embryology

• Genetics

• Ecology

• Evolutionary Biology

What is the role of molecular biology in understanding evolution?

• It examines genetic similarities and differences to trace evolutionary relationships.

• It focuses solely on the physical characteristics of organisms.

• It studies the behavior of organisms in their environment.

• It analyzes fossil records to determine species age.

Who proposed the idea that organisms best suited for their environment would survive and pass on beneficial traits?

• Lamarck

• Mendel

• Darwin

• Wallace
