What is the Best Way to Test a Hypothetical Evolutionary

Question

What is the best way to test a hypothetical evolutionary classification among living organisms?
A) analysis of embryonic development
B) analysis of physical structures
C) analysis of DNA sequence
D) analysis of habitat

Accepted Answer

Analysis of DNA sequence would be the best way to test a hypothetical evolutionary classification among living organisms because it provides the most data and evidence for relatedness and evolutionary history. Embryonic development and physical structures can also provide information, but may not be as reliable or comprehensive as DNA analysis. Habitat alone is not necessarily a reliable indicator of evolutionary relationships.
