Chapter 22: Descent with Modification: Darwinian View of Life Lecture Outline Overview: Darwin Introduces a Revolutionary Theory On November 24, 1859, Charles Darwin published On the Origin of Species by Means of Natural Selection. Darwin?s book drew a cohesive picture of life by connecting what had once seemed a bewildering array of unrelated facts. Darwin made two major points in The Origin of Species: Today?s organisms descended from ancestral species that were different from modern species. Natural selection provided a mechanism for this evolutionary change. The basic idea of natural selection is that a population can change over time if individuals that possess certain heritable traits leave more offspring than other individuals.
