Answer
Evidence supporting the Theory of Evolution
Solution
a
Fossil Record: The fossil record provides chronological evidence of species evolving over time. ⚹ Fossils show a progression of organisms from simple to more complex forms, and transitional fossils demonstrate intermediary stages between groups. ⚹
b
Comparative Anatomy: Homologous structures indicate common ancestry among different species. ⚹ For example, the similar bone structures in the limbs of humans, birds, and whales suggest they evolved from a common ancestor. ⚹
c
Genetic Evidence: DNA comparisons reveal similarities among different organisms, indicating a shared evolutionary history. ⚹ The more closely related two species are, the more similar their genetic sequences. ⚹
d
Biogeography: The geographic distribution of species supports evolution, as organisms tend to be more closely related to others in the same area. ⚹ This pattern is explained by the migration and diversification of species from common ancestors in these regions. ⚹
Key Concept
The Theory of Evolution is supported by multiple lines of evidence from various scientific fields.
Explanation
These evidences collectively demonstrate how species have changed over time and share common ancestors, which is the essence of evolutionary theory.
