Understanding Evolutionary Concepts

Who proposed the theory of evolution by natural selection?

• Gregor Mendel

• Charles Darwin

• Isaac Newton

• Albert Einstein

What is the main idea behind the theory of evolution by natural selection?

• Species remain unchanged over time

• Species evolve over generations through the inheritance of traits

• All species are created independently

• Evolution occurs in a single generation

Why is the concept of evolution important?

• It explains the diversity of life on Earth

• It describes the chemical composition of water

• It predicts weather patterns

• It defines the laws of motion

What are the types of differences that individuals in a species can show?

• Physical, behavioral, or physiological

• Emotional, spiritual, or mental

• Cultural, social, or economic

• Historical, geographical, or political

Why is variation crucial for natural selection?

• It allows for the survival of the fittest

• It ensures all individuals are identical

• It prevents any changes in species

• It stops evolution from occurring

What is the key mechanism that allows natural selection to shape species over time?

• Genetic inheritance

• Environmental changes

• Random mutations

• Artificial selection

How are traits passed on from one generation to the next?

• Through genetic inheritance

• By environmental influence

• Via cultural transmission

• Through random chance

What is the result of organisms producing more offspring than can survive?

• Increased biodiversity

• Competition for resources

• Decreased population size

• Stable ecosystem

Which individuals are more likely to survive and reproduce according to the principle of "Survival of the Fittest"?

• Individuals with fewer offspring

• Individuals with advantageous traits

• Individuals with more food

• Individuals with larger size

Over time, what happens to beneficial traits in a population?

• They become less common

• They remain the same

• They become more common

• They disappear
