What is Darwin's theory in a nutshell?
Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce.
How was Darwin's theory developed?
Unlike Lamarck, Darwin proposed common descent and a branching tree of life, meaning that two very different species could share a common ancestor. Darwin based his theory on the idea of natural selection: it synthesized a broad range of evidence from animal husbandry, biogeography, geology, morphology, and embryology.
How do sexual and asexual reproduction affect Darwin's theory?
How can fossils be used to understand Darwin's theory?
This supports Darwin's theory of evolution, which states that simple life forms gradually evolved into more complex ones. Evidence for early forms of life comes from fossils.
What is modern evidence for Darwin's theory?
Important modern-day examples of evolution include the emergence of drug-resistant bacteria and pesticide-resistant insects.
What is the impact of Darwin's theory on modern biology?
Darwin founded a new branch of life science, evolutionary biology
Compare and contrast microevolution and macroevolution.
Microevolution happens on a small scale (within a single population), while macroevolution happens on a scale that transcends the boundaries of a single species.
