Difficult

Lucy Should Be...

ACTSCI-K7WCFS

Base your answers to this question on this passage, as well as information from the original passage and data chart, as another scientist presents her findings concerning the Lucy fossil.

Scientist #3

I have also done research on the reconstructed fossil. My study focused on reconstructing the inner ear of the fossil. We can learn quite a bit from the construction of the inner ear, including how the specimen kept its balance, how it stood, how it walked, and how it could live. My research shows that the position, shape, length, and structure of the inner ear canal would have Lucy needing four limbs to balance herself while walking, as she would need more surface area to support her weight. We also learned from the structure that the pressure in the inner ear would allow her to live comfortably at slightly higher altitudes.

Is Lucy a Human or an Ape

According to all the information presented, Scientist #3 would most likely believe Lucy should be classified as

A

a human, as the evidence presented matches up with the rib bone data and tooth optics.

B

an ape, as the evidence presented matches up with the rib bone data and tooth optics.

C

a human, as the evidence matches up with a flexible wrist shape.

D

an ape, as the evidence matches up with a stiff wrist shape.
