• B. It is widely accepted that natural selection leads to evolution
• C. Despite the diversity of organisms on Earth, all share the same genetic code
• D. All populations experience mutation and natural selection
• E. Selection acts on individuals, but only populations evolve

Answer 1

The correct option is C Despite the diversity of organisms on Earth, all share the same genetic code
