Practice Quiz #1 Evolution and Natural Selection Quiz

Explain the difference between a Scientific Theory and the use of the word theory in everyday language.

• A scientific theory is a robust explanation based on evidence, while 'theory' in everyday language often means a guess or speculation.
• A scientific theory is just a hypothesis that hasn't been proven yet.
• In everyday language, a theory is always a scientific fact.
• A scientific theory is a simple idea that anyone can understand.

What is Evolution:

• Evolution is the process of creating new species in a laboratory.
• Natural Selection is the intentional breeding of plants and animals by humans.
• Survival of the fittest means only the strongest individuals survive in all environments.
• Evolution is the change in the heritable characteristics of biological populations over successive generations.

What is Natural Selection:

• Natural selection is a process that only occurs in plants.
• Natural selection is the same as artificial selection.
• Natural selection is a theory that has been completely disproven.
• Natural selection is the mechanism by which evolution occurs, favoring traits that enhance survival and reproduction.

What is Artificial Selection: :

• Artificial selection refers to the natural evolution of species over time.
• Artificial selection is the process of eliminating all traits in a species.
• Artificial selection is a random process that occurs in nature.
• Artificial selection is the intentional breeding of organisms to produce desired traits.

What is Common Descent:

• Common descent is a method for classifying organisms based on their habitats.
• Common descent is the idea that species evolve independently.
• Common descent is the theory that all living organisms are related through a common ancestor.
• Common descent refers to the process of natural selection.

What is Fitness:

• Fitness is only about losing weight.
• Fitness is the same as yoga practice.
• Fitness is a type of diet plan.
• Fitness is the ability to live long enough to pass on successful traits to offspring.

What is Adaptation:

• Adaptation is the migration of organisms to different habitats.
• Adaptation refers to the physical changes in the climate.
• Adaptation is the process of creating new species.
• Adaptation is the adjustment of organisms to their environment for better survival.

What is Survival of the fittest:

• The process by which individuals better adapted to their environment survive and reproduce.
• The belief that survival is determined solely by luck and chance.
• A theory that suggests all species are equally adapted to their surroundings.
• The idea that only the strongest survive regardless of their environment.

How do evolution and natural selection relate to each other?

• Natural selection is a key mechanism of evolution that drives the adaptation of species.
• Evolution occurs only through genetic mutations.
• Natural selection is unrelated to evolution.
• Natural selection is a process that happens after evolution.

Explain the natural selection, Principle #1. Variation:

• Variation is the survival of the fittest individuals in a population.
• Variation refers to the process of evolution over time.
• Variation is the adaptation of species to their environment.
• Variation is the differences in traits among individuals in a population.
