Two scientists studied patterns of evolution in the fossil record. Many species they analyzed showed periods of slow changes interrupted by a period of rapid change.

 

This pattern of periods of slow change interrupted by periods of rapid change with few, if any transitional fossils, best describes the theory of —

• natural selection

• genetic drift

• punctuated equilibrium

• gene flow

When multiple transitional fossils are found in many rock layers, they provide evidence of —

• seasonal variation in the diet of a species

• gradual change of a species over time

• DNA functioning as the genetic material of organisms

• an unchanging environment

Farmers spray pesticides on their plants to protect the plants from being eaten by insects. Some individual insects have a genetic mutation that makes them resistant to the toxins in the pesticides. 

 

Which statement best describes how only a few resistant individuals resulted in the pesticide becoming ineffective?

• The resistant insects change the toxin on the plants, making it safe for others.

• The resistant insects grow larger and eat less of the plants.

• The resistant insect eat the contaminated surface and leave the rest for others.

• The resistant insects are bale to survive and reproduce and create a population that is also resistant.

The diagram shows green and brown caterpillars on a tree. Which result is most likely to occur to the caterpillar population due to predation over time?

• The number of brown caterpillars will increase.

• There will be more green caterpillars than brown caterpillars.

• The number of brown caterpillars will decrease.

• The green caterpillars will move to a different type of tree.
