Global warming increasingly affects many aspects of our environment, from the sea level to tropical storm strength. But that's far from the full story. This news brief from July 2006 describes how global warming has already begun to affect the evolution of several species on Earth.

- There is a fit between organisms and their environments, though not always a perfect fit.
- Evolution results from natural selection acting upon genetic variation within a population.
- Natural selection and genetic drift act on the variation that exists in a population.
- Natural selection acts on phenotype as an expression of genotype.
- Phenotype is a product of both genotype and the organismís interactions with the environment.
- Inherited characteristics affect the likelihood of an organismís survival and reproduction.
- Traits that confer an advantage may persist in the population and are called adaptations.
- A hallmark of science is exposing ideas to testing.
- Scientists test their ideas using multiple lines of evidence.
- Scientists use multiple research methods (experiments, observational research, comparative research, and modeling) to collect data.
