Evolution Clicker Questions Biology

Which of the following is NOT an example of a fossil?

• A bone

• A footprint

• A shell

• A feather impression

• All could be fossils

Radiometric (measuring the rates of decay of certain radioactive isotopes) dating of the surrounding rock is the only way to obtain an absolute date for a fossil.

• True

• False

What is Archaeopteryx Lithographica?

• The largest species of finch found on the Galapagos islands

• A peppered moth from England

• A transitional fossil between reptiles and birds

• A very expensive kind of cheese

• None of the above

Which of the following differences between Hyracotherium and Equus is correct?

• Hyracotherium was much larger

• Equus is extinct

• Hyracotherium had simple teeth used for browsing on leaves

• Equus has 4 toes instead of one hoof

• All are correct

The main differences between the finches on Galapagos are the beak size and shape. Competition for food resources is what drove natural selection to favor different beak shapes.

• True

• False

Vestigial structures are -

• Structures found in different species that have similar functions

• Structure with different appearances and functions but have a common ancestor

• Examples of convergent evolution

• Non-functional structures left over from an organism's evolutionary past

Similar habitats often place similar selection pressures on different species. This often leads to unrelated species having features in common. What is this an example of?

• Vestigial structures

• Convergent evolution

• Homologous traits

• Artificial selection

If. a person wanted flies with lots of bristles on their abdomens as pets, he could achieve this by only allowing the flies with the most bristles on their abdomens to reproduce. What would this be an example of?

• Heterozygote advantage

• Natural selection

• Adaptive radiation

• Stabilizing selection

• Artificial selection

Fossils and natural selection aren't the only evidence for evolution. Comparative anatomy, vestigial structures, and molecular biology also provide evidence for evolution.

• True

• False

Continental drift is the --

• The formation of canyons by water erosion

• Slow movement of plates across the earths surface

• The accumulation of different traits in species separate by large areas

• The splitting of one species into two distinct species

• The rise of sea level caused by increased global temperatures
