Name:__________________________ Class:_____ Date:__________ Self Assessment: Natural Selection 1. What is natural selection? a. an active process guiding adaptations toward a specific goal b. a passive process relying on environmental factors to drive change c. a human-controlled process that we change every day d. an active process depending on an organism's activity during its lifetime 2. Which of the following could cause an adaptation? a. a finch with a wide, short beak deciding it wants its offspring to have long narrow beaks b. a bear dying from starvation so that other offspring know not to go to that stream next season c. a finch with a long, narrow beak living to reproduce offspring with similar beaks d. a bear showing its offspring a stream so they know where the best salmon is 3. The pressure of finite resources refers to the fact that ____________________. a. there is only so much food, water, and shelter in a community for all organisms b. evolutionary processes have a final goal they are striving towards c. organisms can always find the resources they need in some way or another d. there are only so many natural resources and humans are under pressure to use them now 4. All individuals of a species that live in a defined area is called a _____________. a. community b. group c. gang d. population 5. Differential reproductive success is _________________. a. some individuals in a population producing more viable offspring than other individuals b. the amount of difference in how populations reproduce c. the amount of successful reproductions that occur within a population d. one individual organism's success at producing viable offspring PAGE 1 Name:__________________________ Class:_____ Date:__________ Self Assessment: Natural Selection 6.
