Evidence for Evolution Quiz

Which of the following fields studies the chemical processes in organisms as evidence for evolution?

• Paleontology

• Biogeography

• Embryology

• Biochemistry

What does the fossil record primarily reveal?

• The embryonic development of organisms

• The history and age of organisms that lived on Earth

• The geographical distribution of species

• The chemical processes in organisms

How did Darwin use biogeography to support his theory of evolution?

• By observing species variations on islands

• By comparing DNA sequences

• By studying the chemical processes in organisms

• By examining the fossil record

What does embryology suggest about vertebrates?

• They have no common ancestry

• They have similar embryonic development stages

• They have different DNA sequences

• They have no anatomical similarities

Which type of structure has a similar function but a different structure, indicating convergent evolution?

• Transitional fossils

• Analogous structures

• Vestigial structures

• Homologous structures

What are vestigial structures?

• Structures that are only found in extinct species

• Structures with similar functions but different structures

• Structures that are identical in all organisms

• Structures with no function that suggest common ancestry

Which of the following is an example of a homologous structure?

• Wings of a bat and wings of an insect

• Forearm of a human and forearm of a whale

• Fins of a fish and wings of a bird

• Legs of a frog and wings of a bird

What does a high similarity in DNA sequences between two species suggest?

• They have different evolutionary paths

• They share a recent common ancestor

• They are distantly related

• They have no common ancestor

What are pseudogenes?

• Non-functional DNA sequences resembling genes

• Genes that are only found in extinct species

• Genes that are identical in all organisms

• Functional genes that code for proteins

How genetically similar are humans to chimpanzees?

• 75%

• 50%

• 100%

• 98.6%
