Study Notes
Evolution Overview
- Evolution refers to the change in organisms over time, leading to the emergence of new species.
- The process of evolution is primarily driven by natural selection, which is also termed "survival of the fittest."
Natural and Artificial Selection
- Natural selection promotes the survival and reproduction of organisms best adapted to their environment.
- Artificial selection involves human intervention, leading to the development of various traits, such as different dog breeds.
Evidence Supporting Evolution
- Evolution is supported by various types of evidence, including anatomical, fossil, and molecular evidence.
Anatomical Evidence
- Anatomical evidence includes structures that provide insights into evolutionary relationships:
- Vestigial structures, such as the non-functional legs of a skink, are remnants from ancestors indicating evolutionary history.
- Homologous structures, like the forelimbs of bats and whales, show how different species share a common evolutionary origin.
Fossil Evidence
- Fossil records provide critical support for evolutionary theory, with significant finds such as whale bones demonstrating transitions between species over time.
Molecular Evidence
- DNA analysis offers molecular evidence supporting the connections between species and their evolutionary paths.
Historical Context of Evolution
- Charles Darwin, a notable naturalist, established foundational concepts of evolution through his work and observations.
- Darwin traveled to the Galapagos Islands, where he studied unique species such as finches and turtles, which informed his principles of natural selection.
Observational Findings
- Darwin observed variations in finch beaks, adapted to different food sources.
- He also noted the diversity in turtle shell shapes, reflecting adaptations to their specific environments.
