Study Notes
Scientific Method
- Science is a process, not a set of facts
- Scientific stories are provisional and can change
- Observations and data can lead to new knowledge
- All scientific explanations are subject to change with new data
Evolution
- The scientific study of the history of life on Earth
- Evolution is the change in the heritable characteristics of biological populations over successive generations
- Evolution is based on the idea that all life on Earth shares a common ancestor
Darwin's Theory
- Evolution occurs through natural selection
- The key findings of the theory:
- Variation exists within populations
- Some variation is heritable
- Reproduction is not random; those with traits better suited to the environment are more likely to survive and reproduce
- Variation in traits and reproduction affect the genetic makeup of a population
Scientific Process
- The process of doing science involves six steps:
- Science is performed within a rational and naturalistic framework
- Experimental and observational support is required for explanations
- Choose the simplest explanation consistent with the data (Occam's Razor)
- Compile and test data repeatedly
- Compile and disseminate scientific knowledge
- Accept the uncertainty of scientific knowledge
Evolutionary Processes
- Microevolution: changes in allele frequencies in populations over time, driven by natural selection, genetic drift, and gene flow
- Macroevolution: changes above the level of a species, often resulting in new species and diversification throughout a lineage
Prior Knowledge and Influences
- Prior knowledge, including observations and theories, can influence scientific discoveries
- Population growth and food limitations, ideas about variation in nature, natural history research, and prior theories influenced Darwin's research
- Darwin's work on natural selection built upon existing scientific thought and observations
