What does the theory of evolution explain about species?
- Species have been created as distinct types by God.

What is one implication of extinction in evolutionary theory?
- All species will eventually go extinct.
- Extinction provides evidence that species are changing. (correct)
- Extinction negates the concept of gradual evolution.

Study Notes
Evolution Overview
- The theory of evolution has replaced the theory of special creation, which claims that each species was uniquely created by God.
- Evolution asserts that species have undergone changes over time, marking a shift in scientific understanding.
Change Through Time
- Fossils serve as physical evidence of past organisms, informing us about the history of life on Earth.
- Fossil dating utilizes radiometric and geological techniques to determine ages and contexts.
- The fossil record comprises all known fossils, providing a timeline for evolutionary changes.
Extinction
- Extinct organisms are those that have left fossils but no longer exist, indicating species change over time.
- Extinction evidence supports gradual evolution, although its overall convincingness can be debated.
Transitional Forms
- Discovery of similar species following the disappearance of a species in the fossil record suggests evolutionary changes over time.
- Such transitions are often localized, increases in geographic correlation provide further support for evolutionary theory.
Vestigial Traits
- Vestigial traits are nonfunctional structures that resemble functional ones in closely related species.
- These traits provide insight into evolutionary history and the concept of common ancestry.
Directly Observed Evolution
- Some evolutionary changes occur rapidly and can be directly observed in real-time.
- Key examples include:
- Ground finches showcasing rapid adaptations.
- Observations of tuberculosis evolving in response to treatments.
- E. coli studies that illustrate quick evolutionary changes in laboratory settings.
