Natural selection explains the complexity of living organisms from "summary" of The Origin of Species by Charles Darwin
Natural selection is the process by which individuals that are best adapted to their environment are more likely to survive and reproduce. This process leads to the gradual accumulation of favorable traits within a population, resulting in the diversity and complexity of living organisms that we see today. Through the mechanism of natural selection, simple variations in organisms can lead to the development of complex structures and functions over time. The concept of natural selection provides a simple and elegant explanation for the complexity of living organisms. By focusing on how organisms interact with their environment and how certain traits are passed on to future generations, natural selection offers a clear and logical framework for understanding the diversity of life on Earth. This process of “descent with modification” allows for the gradual emergence of new species and the adaptation of organisms to changing environmental conditions. In the struggle for existence, individuals with advantag...
