  1. Physiology

  2. Fossils

  3. Phylogeny

  4. Morphology
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • Modern taxonomy is based on the hypotheses' of the evolutionary history of organisms, known as Phylogeny. As with the scientific method, scientists develop a hypothesis on the history of an animal and utilize modern science and technology to prove phylogeny.
  • With the advent of such fields of study as phylogenetics, cladistics, and systematics, the Linnaean system has progressed to a system of modern biological classification based on evolutionary relationships between organisms, both living and extinct.
  • So the correct option is 'phylogeny'.
