Charles Darwin's theory of natural selection is a cornerstone of modern biology, revolutionizing our understanding of evolution. This theory explains how species adapt and change over time, driven by environmental pressures and genetic variation. In this article, we delve into the intricacies of Darwin's natural selection, providing a detailed answer key for a comprehensive worksheet designed to test your knowledge.
What is Natural Selection?
Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring. The theory was first fully articulated by Charles Darwin in his groundbreaking work, 'On the Origin of Species,' published in 1859. Darwin's observations of finches on the Galapagos Islands provided compelling evidence for his theory, showing how slight variations in beak shape and size allowed different species to exploit different food sources.
