Darwin‟S Theory Evolution MDCAT Quiz: Darwin’s Theory of Evolution by natural selection is one of the most important concepts in biology. Proposed by Charles Darwin, this theory explains how species evolve over time through the process of natural selection, where organisms with traits better suited to their environment are more likely to survive and reproduce. Understanding Darwin’s theory is crucial for MDCAT preparation, especially for questions related to evolutionary biology, genetics, and the diversity of life. To enhance your knowledge, practicing with an MDCAT Quiz focused on Darwin’s theory will help solidify your understanding and improve your exam readiness.
The Main Concepts of Darwin’s Theory of Evolution
Darwin’s theory rests on several key concepts:
Variation: Within any population, individuals display variations in their traits, such as size, color, and shape. These variations arise due to genetic differences, with some being inherited and others occurring due to mutations.
Struggle for Existence: The organisms are in a struggle for limited food, shelter, and mates. Not every individual in a population survives to reproduce; therefore, this competition results in a struggle for existence.
Natural Selection: Natural selection is a process in which useful traits for the survival and reproduction of organisms become common in a population over time. Such individuals who possess advantageous traits—for instance, good camouflage, speed of movement, strong immune systems—are more likely to survive, reproduce, and pass those advantageous traits to their offspring.
Descent with Modification: Over a period, natural selection leads to changes in populations. Gradually, these changes can build up to produce new species from a common ancestor. This process, when described, is called descent with modification because the existing changes are cumulative across generations.
