Darwin’s Theory of Evolution: A Comprehensive Overview: Chapter 15 Darwin’s Theory Of Evolution Answer Key

Charles Darwin’s theory of evolution by natural selection revolutionized our understanding of life on Earth. This groundbreaking theory, published in 1859 in his seminal work “On the Origin of Species,” laid the foundation for modern evolutionary biology.

Darwin’s theory is based on the concept that all living organisms share a common ancestor and that over time, they have evolved through a process of natural selection. This process involves the following key tenets:

• Variation: Individuals within a species exhibit variation in their traits.
• Inheritance: These variations can be passed on from parents to offspring.
• Overproduction: Populations tend to produce more offspring than can survive and reproduce.
• Selection: Individuals with traits that enhance their survival and reproduction in a particular environment are more likely to pass on their genes to the next generation.

FAQ

What is the central tenet of Darwin’s theory of natural selection?

The central tenet of Darwin’s theory of natural selection is that individuals with traits that make them better adapted to their environment are more likely to survive and reproduce, passing on those advantageous traits to their offspring.

How does comparative anatomy support Darwin’s theory?

Comparative anatomy provides evidence for the shared ancestry of different species by comparing the similarities and differences in their anatomical structures. This supports the idea that species have evolved from a common ancestor.

What is the difference between microevolution and macroevolution?

Microevolution refers to small-scale evolutionary changes within a species over a relatively short period of time, while macroevolution refers to large-scale evolutionary changes that result in the formation of new species or the divergence of existing species over long periods of time.
