Natural Selection Review

How do fossils provide evidence for evolution?

• Fossils show the historical progression of life forms and can demonstrate changes in species over time, supporting the theory of evolution.

• Fossils are simply remnants of ancient organisms with no relevance to evolutionary theory.

• Fossils only represent the organisms that existed at a single point in time, not their changes over time.

• Fossils are primarily used to date rocks and have no connection to the evolution of species.

How does the environment influence natural selection?

• The environment has no effect on natural selection.

• The environment determines which traits are advantageous, thus influencing which organisms survive and reproduce.

• Natural selection is solely based on genetic mutations, independent of the environment.

• The environment only affects the physical characteristics of organisms, not their survival.

What is the difference between artificial selection and natural selection?

• Artificial selection is the process by which humans breed organisms for desired traits, while natural selection occurs without human intervention.

• Artificial selection occurs naturally, while natural selection is a human-driven process.

• Both artificial and natural selection are processes that occur without human influence.

• Artificial selection is a random process, while natural selection is a deliberate choice made by humans.

What is the role of mutation in evolution?

• Mutation has no effect on genetic variation.

• Mutation introduces new genetic variations in a population, which can lead to new traits that may be beneficial for survival.

• Mutation only occurs in response to environmental changes.

• Mutation is a process that eliminates harmful traits from a population.

What is an adaptation?

• A characteristic that decreases an organism's ability to survive

• A trait that enhances an organism's ability to survive and reproduce in its environment

• A random mutation with no effect on survival

• A behavior that is learned over time

What is the impact of overpopulation on natural selection?

• Overpopulation leads to an increase in biodiversity.

• Overpopulation can lead to competition for resources, which can drive natural selection as only the fittest individuals survive.

• Overpopulation has no effect on natural selection.

• Overpopulation results in a decrease in the number of species.

Who proposed the theory of natural selection?

• Charles Darwin

• Albert Einstein

• Isaac Newton

• Galileo Galilei

What is natural selection?

• Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.

• Natural selection is the method by which species become extinct due to environmental changes.

• Natural selection is the phenomenon where all organisms have an equal chance of survival regardless of their traits.

• Natural selection is the practice of breeding organisms with desirable traits to enhance their survival.

What is the difference between genotype and phenotype?

• Genotype refers to the observable traits of an organism, while phenotype is the genetic makeup.

• Genotype is the physical appearance of an organism, while phenotype is the genetic information.

• Genotype refers to the genetic makeup of an organism, while phenotype is the observable physical or behavioral traits.

• Genotype and phenotype are two terms that mean the same thing.

What is the concept of fitness in evolutionary biology?

• Fitness refers to an organism's ability to survive and reproduce in its environment.

• Fitness is the physical strength of an organism compared to others.

• Fitness is the amount of food an organism can consume in a day.

• Fitness is the speed at which an organism can move.
