Question

Is the cladogram pictured here correct? Does it accurately represent the cladistic relationships between these species based on their derived characteristics? Why or why not?

Answer 1

The cladogram is correct. The further explanation is given below.

Step-by-step explanation:

• As with most other species excluding lamprey, paired arms and legs are established.
• In any organism except lamprey as well as tuna, paired legs become available.
• Throughout all animals, except lampreys, tuna, certain bullfrogs, the amniotic membrane seems to be preserved.
• In kangaroos, rhesus monkeys including people, mammary glands were only ever available.
• The placenta has only been found throughout rhesus monkeys and also in humans.
• Foramen magnum forward will be exclusively found in humans.
