Science
Evidence of evolution.
Definition
Multiple lines of scientific evidence support the theory of evolution, including fossil records, comparative anatomy (homologous and vestigial structures), embryology, molecular biology (DNA/protein comparisons), and biogeography. Together, these demonstrate that species change over time and share common ancestors.
Examples
Real-world.
- 1 Fossil sequences showing horse evolution from small multi-toed ancestors
- 2 Human arm, whale flipper, and bat wing sharing the same bone structure (homologous structures)
- 3 DNA comparisons showing humans and chimpanzees share about 98% of their genome
