Dicots · Botany

Dicotyledons are considered more primitive or more advanced compared to Monocotyledons?

  1. More advanced because they have two cotyledons.
  2. They evolved at the exact same time independently.
  3. There is no evolutionary relationship between them at all.
  4. More primitive, as Monocots evolved later from dicots
Show answer and explanation

Correct answer: More primitive, as Monocots evolved later from dicots

Molecular and fossil evidence suggest that Monocots are a monophyletic group that diverged from ancestral dicot-like angiosperms. Thus, the dicotyledonous body plan is considered more basal in angiosperm evolution.
