Question

Which clade does not include humans?
A) diapsids
B) craniates
C) synapsids
D) lobe fins

Answer 1

your answer is option A

Answer 2

Answer:

Diapsids clade does not include humans.

Explanation:

• The group of organisms with two temporal fenestrae (holes in the temporal bone) on either side of the skull is known as a diapsid. Most members of the classes Reptilia and Aves exhibit this characteristic.
• Therefore, neither humans nor any other mammals belong to the group diapsids.
• A division of the Chordata is known as the clade Craniata. A cranium, which is a bony, cartilaginous, or fibrous structure encasing the brain, jaw, and facial bones, is possessed by members of the Craniata.
• Mammalian creatures, including humans, and certain reptiles, make up the synapsid clade. This clade has a single hole on either side in the temporal bone of the skull, which is frequently referred to as having temporal fenestrae.
• As a result, we can conclude that humans are synapsids.
• The lobe-fin family of bony fishes is a rare species today, yet its fins' lobe structure is similar to that of human limbs. This information together with additional evidence points to the lobe-fins clade as the human ancestor.
• Therefore, humans indeed belong to the clade of lobe-fins.

Hence, option (A) is correct.
