Question

Based on the body structures of these animals, which two conclusions are scientifically sound? The skeletal structure of the gorilla and chimpanzee suggest a common evolutionary ancestry. The dog and frog share a closer evolutionary ancestry than the gorilla and chimpanzee. The dog is more closely related to the frog than it is to the chimpanzee. All four organisms share a common vertebrate ancestor.

There is difference of only one chromosome between human (23) and gorilla & chimpanzees (24).

Hence, option A is correct
