QUIZ 4 HNRS - EVOLUTION

The hypothesis that species change over time through natural selection was proposed by

• Charles Darwin

• Jean-Baptiste Lamarck

• Gregor Mendel

• Anton van Leeuwenhoek

According to binomial nomenclature, an organism's scientific name is composed of:

• Order and species

• Genus and species

• Class and phylum

• Genus and family

Structures that have similar structure but different functions (example: whale flippers, bat wings, and human arms) are:

• analogous structures

• homologous structures

• ancestral structures

• vestigial structures

When lions prey on a herd of antelopes, some antelopes are killed and some escape. Which part of Darwin's concept of natural selection might be used to describe this situation?

• Artificial selection

• Descent with modification

• Survival of the fittest

• Reproductive isolation

Which of the following is a behavioral adaptation?

• Birds migrating south for the winter

• Butterflies having a long tongue to drink nectar from flowers

• Snakes use venom to aid in attacking prey

• Cats have sharp claws that help them climb and catch food

Domestic horses that have been bred by humans in captivity have more variation in coat colors horses seen in the wild. What process most likely led to the greater coat color variation in domestic horses?

• Natural selection

• Cloning

• Artificial selection

• Evolution

Long ago, in a snowy environment there was a population of rabbits who had brown fur. A random mutation introduced white fur to the population, and over time, more and more rabbits with white fur have survived and passed on their fur color to the next generation. Today, almost all of the rabbits in this environment have white fur. This would be an example of:

• Natural selection

• Artificial selection

• Extinction

• Facilitated diffusion

Comparing the very early stages of vertebrate development as a means of determining the relatedness of organisms is called

• Comparative embryology

• The fossil record

• Comparative cytology

• Bioeographical evidence

Two organisms that are in the same ________ would be the most closely related.

• Phylum

• Class

• Order

• Genus

A bird's wing and a fly's wing both have the same function, but their structure is very different. This is the result of:

• Convergent evolution

• Divergent evolution

• Speciation

• Adaptive radiation
