Study Notes
Evolution
- Evolution is the change in gene frequency in a population's gene pool over several generations.
- Evolutionary change occurs within a population over many generations, not in individual organisms within their lifetime.
- Evolution occurs in gene pools, not genomes.
- There are two scales of evolution: microevolution (small scale, causing a change in allele frequency) and macroevolution (larger scale, leading to the creation of new species).
Charles Darwin
- Charles Darwin was an English naturalist, biologist, and geologist who proposed the theory of natural selection as a mechanism for evolution.
- He was born in 1809 in Shrewsbury, England, and initially studied medicine at Edinburgh University in Scotland.
- Darwin's passion for natural history led him to focus on it instead of medicine, and he eventually embarked on a voyage aboard the HMS Beagle in 1831.
- During the voyage, Darwin collected numerous samples of plants, animals, rocks, and fossils, which he sent back to England for further study.
- Upon his return, Darwin's work led to groundbreaking scientific discoveries, including the understanding of fossil formation and the shaping of the Earth's surface.
Darwin's Theory of Natural Selection
- The theory of natural selection states that individuals with traits best suited to their environment are more likely to survive and pass on their genes to the next generation.
- This leads to the widespread adoption of such traits in a species and can eventually result in the development of a new species.
- Darwin published his thoughts on evolution and natural selection in On the Origin of Species in 1859.
- The book was popular and controversial, suggesting that the planet was much older than commonly believed at the time.
Darwin's Big Ideas
- Darwin's two main ideas about the change in species over time are the mechanism of natural selection and the concept of common descent.
- The concept of common descent proposes that all organisms alive on Earth today originated from a common ancestor.
