Unraveling the Mechanism of Evolution: A Simplified Understanding of Darwin’s Theory of Natural Selection
Introduction Charles Darwin’s theory of evolution by natural selection revolutionized our understanding of life on Earth. Before Darwin, the prevailing belief was that species were created in their current forms and did not change over time. However, Darwin's groundbreaking work, particularly in his book On the Origin of Species (1859), provided a comprehensive framework for understanding how species evolve over...
Questions with answers on “Darwin’s Theory of Evolution: Natural Selection Simplified.”
1. What is the concept of natural selection as proposed by Darwin, and how does it contribute to evolution? Answer:Darwin's concept of natural selection suggests that in nature, individuals within a population vary in their traits, and those traits that provide a survival advantage are more likely to be passed on to future generations. The individuals best adapted to their...
