#Part-A Aptitude & General Biotechnology
  1. arthropods have had more time to co-evolve with land plants than have vertebrates.
  2. extant terrestrial arthropods are better adapted to terrestrial life than are extant terrestrial vertebrates.
  3. ancestral arthropods must have been poorly adapted to aquatic life, thus experienced a selective pressure to invade land.
  4. vertebrates evolved from arthropods.
