Answer

Brief Explanations:

To determine the best definition of a phylogenetic tree, we analyze each option:

  • The first option is incorrect because phylogenetic trees are not just based on physical characteristics and are not tables.
  • The second option describes the taxonomic hierarchy (like domain, kingdom, etc.), not a phylogenetic tree.
  • The third option is correct: a phylogenetic tree is a branching diagram that shows the evolutionary relationships (like common ancestors, divergence) among organisms.
  • The fourth option describes a general classification approach, not specifically a phylogenetic tree's definition.

Answer:

C. a branching chart that depicts evolutionary relationships among organisms
