D. Bird wings and insect wings

Multiple ChoiceTraits that allow an organism to survive and produce offspring are called

A. variations

B. adaptations

C. Vestigial structures

D. Homologous structures

Multiple ChoiceScientists use all of the following to support the theory of evolution through natural selection EXCEPT

A. Fossil evidence

B. Comparative anatomy and homologous structures

C. Vestigial structures

D. Genetic engineering

Multiple ChoiceDarwin’s theory of evolution is based upon the concept of

A. Selective breeding

B. mutations

C. Natural selection

D. hybridization

Multiple ChoiceDNA copying errors can cause changes in the traits of organisms. These copying errors are called

A. Homologous structures

B. genes

C. variations

D. mutations

Multiple ChoiceVestigial structures

A. Include root hairs in plants and the elaborate camouflage of certain spiders

B. Are beneficial adaptations

C. No longer exist

D. Have no function in present organisms

Multiple ChoiceThe preserved remains or traces of an organism that lived in the past

A. mutations

B. fossils

C. vestigal structures

D. adaptations

Multiple ChoiceEvolution is best defined as

A. Gradual change in a species over time

B. The passing of traits from one generation to the next

C. The process of one species turning into another species

D. Differences between members of a species

Multiple ChoiceThe spotted touch-me-not is a flowering plant. It has seed pods that burst open when touched and forcefully eject their seeds. This adaptation is beneficial because it

D. Conserves the plant’s energy

C. Helps disperse the seeds of the plant

A. Causes genetic changes in the plant

B. Attracts insects that pollinate the plant

Multiple ChoiceWhich of the following is an example of mimicry?

A. Elephants traveling in herds

B. Zebras confusing predators using optical illusions

C. Stick insects (walking sticks) that resembles sticks and twigs

D. Swordfish that resemble a Renaissance sword

Multiple ChoiceBird predators eat high percentages of light colored moths in forests where there are high levels of pollution. Dark colored peppered moths are, therefore, better adapted to survive and reproduce. This is an example

D. Artificial selection

C. mutationsA. Natural selection

B. macroevolution

Multiple ChoiceSimilarities in the bone structure of a chimpanzee’s arm and of a bird’s wing

A. Show that the chimpanzees are an older species than birds

B. Provide evidence of a common ancestor for the species

C. Are an example of variations within a species

D. Are an example of vestigial structures
