Chitin is a long-chain polymer derived from glucose. It strengthens cell walls of fungi and the outer covering (exoskeleton) of arthropods (including crabs, shrimps, and insects). The presence of chitin in these groups is likely due to ______.
A. secondary endoparasitism B. horizontal gene transfer C. paraphyletic evolution D. convergent evolution

Respuesta :

Option (D) convergent evolution is correct.

The presence of chitin in these groups is likely due to convergent evolution.

What is convergent evolution ?

  • Convergent evolution is the independently occurring evolution of comparable traits in animals from several epochs or eras of time.
  • Analogous structures that have a similar form or function but were absent from that group's most recent common ancestor are created via convergent evolution.
  • The similarities between shark and dolphin bodies, vertebrate and cephalopod eyes, and bat and insect wings are all examples of convergent evolution.
  • Convergent evolution produces similar structures, but not analogous ones. TCRs/BCRs and VLRs are both antigen receptors, but they are not linked in terms of evolution.
  • Humans and squid have eyes that are structurally similar. Snakes and worms both lack legs when they move.
