Theory of Evolution by Natural Selection

Change in characteristics of living things over time.

• Evolution

• Natural Selection

• Fitness

• Inheritance of Acquired Characteristics

• Mutation

Organisms better fitted to the environment are more likely to survive and reproduce than organisms who aren’t fitted to the environment.

Mistaken idea that animals whose traits changed in their lifetime could pass on those traits to their offspring.

• Inheritance of Acquired Characteristics

• Mutation

Answer explanation

The idea of Inheritance of Acquired Characteristics is not true. Traits that are acquired during an organism's life cannot be inherited by its offspring. In order for a characteristic or trait to be passed down to the next generation, it must be part of the individual's genotype.

Examples of acquired characteristics: large muscles from working out, reading (because it has to be learned), riding a bike (because it has to be learned), an injured body part, etc.

• Artificial Selection

Answer explanation

Random changes in genetic material may result in making different proteins.

• Evolution

• Natural Selection

• Fitness

• Inheritance of Acquired Characteristics

• Mutation

Answer explanation

Mutations cause different proteins to be made by the body. Different proteins build different traits. These mutations can be harmful, beneficial, or neutral.
