The genetic code is nearly universal across all life on Earth. This similarity is best explained by
- A
Random chance producing identical codons across taxa
- B
Convergent evolution toward an optimal coding system
- Ccheck_circle
Shared evolutionary descent from a common ancestor
- D
Independent origin of the same code in each lineage
Explanation
A nearly universal code is strong evidence that all living things descend from a common ancestor (LUCA).
