Evolution part II

This document discusses several lines of evidence that support the theory of evolution, including: 1. The fossil record provides evidence of major changes in climate, geography, and organisms over geological time. While incomplete, it offers a clear picture of evolution for many species. 2. Comparative anatomy finds similarities between living organisms, like homologous and vestigial structures, that support their common descent with modification over time. 3. Biochemical evidence, like similarities in DNA and cell processes across species, also indicates common ancestry rather than independent origin of life forms. 4. The modern synthesis integrates genetics with natural selection and models ancestral relationships between organisms as a branching tree of descent.
