Many organisms have body parts that are actually identical to a other organism which isn't related in the least bit.
A vertebrate is the skeletal units of the spinal column, that protect your spinal cord and keep your body standing upright. A Bony skeleton is a legit skeleton that was created by bones. A tetrapod is an animal that has four limbs. An Amniotic egg is an egg that can be laid on land. Diapsids are two skull openings on the side of your head behind your eyes. Hair is the little filaments growing out of your head. These are all the different body parts organisms have in common.
SP4: Analyzing and interpreting data: We did a game in which we compared the different bones to see which animal is closely related to the T-Rex. The caiman ( small alligator thing ) and the parrot were the last animals to closely relate to the T-Rex. What won out was Parrot because it had almost everything the T-Rex had. It was the same with the caiman except it has heels while the parrot and T-Rex do not.
