Evolution Study Guide

Based on the data table, what can you conclude about the mice population? (AKS 4c)

• The mice with short tails have the better traits for survival in their environment

• The mice with the short tails are better adapted to pass on their traits to their offspring

• The mice with long tails have the better traits for survival in their environment

• The mice with long tails are not as well adapted to pass on their traits to their offspring

Which of the following would provide appropriate evidence as to why natural selection is occurring in the mice example? (AKS 4c)

• The mice with long tails are increasing and the mice with short tails are decreasing

• The mice with long tails have shown significant growth from Year 1 to Year 7, increasing from 120 to 560 mice. The mice with short tails have shown significant decline (decreasing)from Year 1 to Year 7, from 115 to 48

• The mice with long tails are faster runners than the mice with short tails

• The mice with long tails have shown growth from Year 1 to Year 7, decreasing from 120 to 560 mice. The mice with short tails have shown decline (decreasing) from Year 1 to Year 7, increasing from 115 to 48.

If you were to add a third picture to the image above, what would you include? (AKS 4b)

• Squares and circles because the dark circles are surviving best and will mutate into square bacteria.

• More white circles than dark black circles because the dark black circles are surviving the best.

• More gray circles than dark black circles because the gray circles are surviving the best.

• More dark black circles than gray circles because the dark black circles are surviving the best.

The white circles represent weak bacteria; the dark black circles represent strong bacteria. The weak bacteria easily die in the presence of antibiotics. The dark bacteria survive and reproduce in the presence of antibiotics. What of the following best describes how natural selection is occurring? (AKS 4b)

• The white bacteria are better adapted to survive the antibiotics, therefore are reproducing.

• The black bacteria are better adapted to survive the antibiotics, therefore are reproducing.

• The black bacteria are better adapted to survive the antibiotics, therefore are not reproducing.

• The gray bacteria are not as well adapted to survive the antibiotics, therefore are reproducing.

What is the purpose of a fossil record? (AKS 4d)

• To show that all organisms came from one common ancestor.

• To show that all organisms look similar.

• To show the diversity and history of organisms on earth.

• To show the organisms that went extinct due to their survival.

In a desert, what would be a beneficial adaptation for a population of kangaroo rats? (AKS 4a)

• Dark fur to absorb sunlight

• Large ears to detect a predator approaching

• Small, squinty eyes to see prey better at nighttime

• Extra fat to store more heat for warmth

Which of the following describes natural selection the best? (AKS 4a)

• The differences in a population

• Humans selecting for specific traits in a population

• When organisms are better adapted to survive in an environment and can reproduce

• When organisms are not as well adapted in an environment to survive and reproduce

In the arctic, polar bears tend to burrow (dig) underground to protect themselves from heavy snowfall or during hibernation season. The polar bears that are not as skilled in digging usually do not live as long as the ones that are skilled at digging. What is this an example of? (AKS 4e)

• Natural Selection

• Artificial Selection

• Genetic Variation

• Adaptation

What do you predict will happen in the 5th generation of plants? (AKS 4c)

• The plants without thorns will be extinct.

• The plants with thorns will start to decrease and the plants with thorns will start to increase.

• The plants with thorns and the plants without thorns will have the same percentages.

• The plants with thorns will continue to increase and the plants without thorns will continue to decrease.

A scientist is studying mice that run fast. He tests them and separates the fast mice from the slower mice. He wants to make a fast breed of mice, so he decides to keep the fast mice together for them to breed. What is this an example of? (AKS 4e)

• Natural Selection

• Artificial Selection

• Genetic Variation

• Adaptation
