The occurrence of identical genetic code structures and highly conserved metabolic enzymes in geographically isolated species across different continents indicates that these organisms descended from a common ancestor rather than evolving independently.
Answer: Answer
Answer
The statement is True. Comparative biochemistry shows that fundamental molecular features (such as the universal genetic code and conserved enzymes) are shared among geographically isolated organisms, directly supporting common descent.
The statement is correct because comparative biochemistry demonstrates that universal genetic and metabolic machinery across geographically separated species points to a single, shared evolutionary origin.
Step-by-Step Solution
Key Concept
Universal biochemical homologies across geographically separated taxa as evidence for common ancestry.
