Evolution Review

What is evolution?

• Change over time.

• A process of creating new species.

• A method of scientific experimentation.

• A theory that has been disproven.

What is the process by which individuals with inherited characteristics well-suited to the environment leave more offspring?

• Natural Selection

• Artificial Selection

• Genetic Drift

• Mutation

What is the difference between natural selection and evolution?

• Natural selection is a type of evolution that occurs only in animals.

• Natural selection is a mechanism of evolution; evolution is the change in the heritable characteristics of biological populations over successive generations.

• Natural selection and evolution are the same processes that occur simultaneously.

• Natural selection is the process by which organisms adapt to their environment, while evolution is the extinction of species.

What is the role of fossils in understanding evolution?

• Fossils provide evidence of past life forms and their changes over time.

• Fossils are used to date rocks and determine their age.

• Fossils are primarily used to study the chemical composition of ancient organisms.

• Fossils serve as a source of energy for modern organisms.

What is the importance of variation in a population?

• Variation is essential for natural selection, as it provides the raw material for evolution.

• Variation leads to increased competition among individuals.

• Variation decreases the chances of survival for a population.

• Variation has no significant impact on the population's adaptability.

What is natural selection?

• The process where organisms better adapted to their environment tend to survive and produce more offspring.

• A method of breeding plants and animals for desired traits.

• The theory that all species evolve from a common ancestor over time.

• A technique used to create genetically modified organisms.

What is genetic drift?

• A mechanism of evolution that refers to random changes in the frequency of alleles in a population.

• A process that leads to the adaptation of organisms to their environment.

• A method of artificial selection used in breeding programs.

• A phenomenon that occurs only in large populations.

What is the significance of embryology in evolutionary studies?

• It shows similarities in the early development stages of different organisms.

• It provides evidence for the theory of natural selection.

• It explains the genetic mutations in adult organisms.

• It demonstrates the impact of environmental factors on adult morphology.

What does a common ancestor refer to in evolutionary biology?

• An ancestor that two or more descendants have in common.

• A species that has evolved from another species.

• A type of fossil that shows evolutionary change.

• An organism that has no living descendants.

What does the term 'fitness' mean in evolutionary biology?

• The ability of an organism to survive and reproduce in its environment.

• The physical strength of an organism compared to others.

• The speed at which an organism can move in its habitat.

• The size of an organism relative to its species.
