How would DNA of a fish compare to a lion?

Answer 1

The DNA of a fish and a lion would differ significantly due to their evolutionary divergence and adaptations to distinct environments. While both species share a common ancestor and have similar fundamental DNA structures, the specific sequences, gene arrangements, and the number of chromosomes can vary greatly. For instance, fish typically have more genes related to water adaptation, while lions possess genes for terrestrial survival and social behavior. Overall, their genetic differences reflect their unique evolutionary paths and ecological niches.
