Final answer:
The theory of evolution is supported by biochemical evidence such as unrelated organisms using different codons, organisms with common ancestors making similar proteins, and all vertebrates having similar structures early in development.
Step-by-step explanation:
The theory of evolution is supported by biochemical evidence in several ways. One piece of evidence is that unrelated organisms use different codons for amino acids. This suggests that these organisms have evolved independently and their genetic code has changed over time. Additionally, organisms with common ancestors make similar proteins, providing further evidence of shared evolutionary history. Finally, all vertebrates have similar structures early in development, which indicates a common ancestor and supports the theory of evolution.
