Coelacanths and lungfish are collectively known as the lobe-finned fishes, and have fins containing similar arrangements of bone
s to those seen in tetrapod limbs. Which of the following statements about this relationship is TRUE? O Because the fins of the lobe-finned fishes and the limbs of tetrapods are used for different purposes, they can not be homologous.
O Coelacanths and lungfish are considered to be the first tetrapods.
O This relationship is an example of a morphological similarity reflecting a likely evolutionary link.
O Despite the similar morphology of lobe fins and tetrapod limbs, genetic evidence suggests that coelacanths and lungfish are only distantly related to the tetrapods.
Answer:This relationship is an example of a morphological similarity reflecting a likely evolutionary link
Explanation:
Lungfish and Coelacanths are distinct from other fish because they are lobe-finned species.
Lately, major palaeontological studies proposed that Lungfish and Coelacanth form a monophyletic sister group that is related closely to the tetrapods.
A monophyletic group is a group of organisms that include all the descendants and they share a common ancestor.
Qualitative data is when you can see the ecosystems. the importance of biodiversity for all sustainable ecosystems is biodiversity boosts ecosystem productivity whether each species, no matter how small, all have an important role to play.
