The name of the ship that took Darwin on a voyage to the Galapagos Islands.

What is the Beagle?

100

Darwin observed that most species produce more of these than the environment can possibly survive.

What are offspring?

100

This type of evidence from the past, often found in sedimentary rock, supports the idea that species change over time.

What is fossil evidence?

100

The combined genetic information of all members of a particular population.

What is gene pool?

100

The separation of populations by barriers such as rivers or mountains.

What is geographic isolation?

200

During Darwin's voyage on the Beagle, Darwin made many observations on these islands.

What are the Galapagos Islands?

200

The theory proposed by Charles Darwing that suggests species will change over time.

What is the theory of evolution?

200

Structures like the human arm and a bat wing are examples of these, showing common ancestry.

What are homologous structures?

200

When a farmer breeds only the best of his/her livestock.

What is artificial selection.

200

When individuals with the average form of a trait heve the highest fitness.

What is stabilizing selection?

300

The title of a revolutionary book published by Darwin in 1859.

What is On the Origin of Species ?

300

According to Darwin’s theory, individuals with traits better suited to their environment are more likely to do this.

What is survive and reproduce?

300

This explains why the number and location of bones found in fossil vertebrates are similar to those in living vertebrates.

What is common ancestry?

300

Genetic drift tends to occur in populations of this size.

What is small?

300

An example of this is how sharks, dolphins, and penguins all have analogous structures that enable them to move through water.

What is convergent evolution?

400

The word Darwin used to describe the ability of an organism to survive and reproduce in its environment.

What is fitness?

400

Reproductive isolation is necessary for this evolutionary process, where one species splits into two distinct species.

What is speciation?

400

An easily recognized fossil that is useful for dating and correlating the strata in which it is found. 

What is index fossil?

400

A situation where a population of plants has some flowers that open midday and other flowers that open late in the evening.

What is temporal isolation?

400

A pattern of natural selection where larger, heavier beaks are favored after a period of severe drought. 

What is directional selection?

500

This economist wrote about how human populations grow faster than resources, inspiring Darwin’s idea of the “struggle for existence.”

Who is Thomas Malthus?

500

Over many generations, helpful traits become more common in a population through this process.

What is natural selection?

500

This type of structure, like the human appendix or whale pelvis, no longer serves its original function but provides evidence of evolutionary change.

What is a vestigial structure?

500

The type of genetic drift that follows the colonization of a new habitat by a small group of individuals.

What is the founder effect?

500

The geologists who suggested that Earth is many millions of years old.

Who are Hutton and Lyell?
