Question

Which sentence is a logical inference that is supported by this evidence? Wolves are quite similar in appearance to domestic German shepherds. They have common physical traits that include shaggy fur, erect ears, and a heavy, curled tail.

A. Wolves and domestic German shepherds must share common ancestors.
B. Domestic German shepherds are mean like wolves.
C. Domestic German shepherds and wolves can both live in the wild.
D. Wolves can make good domestic pets.

Answer 1

The sentence that wolves and domestic German shepherds must share common ancestors is the logical inference supported by their physical similarities and genetic evidence.

Step-by-step explanation:

Based on the evidence provided, the most logical inference would be that wolves and domestic German shepherds must share common ancestors. This is supported by the physical similarities between the two, such as shaggy fur, erect ears, and a heavy, curled tail. Historically, through selective breeding processes, humans have developed domestic dogs from their wild counterparts. Dogs and wolves share a remarkable amount of genetic material, with a difference of about 0.2%, which further supports that dogs originated from certain wolf subspecies. Additionally, it is well documented in scientific literature that dogs and wolves can interbreed and produce viable offspring, suggesting a close genetic relationship and common ancestry.
