What do scientists use to apply cladistics? a. homologous traits b. homoplasies c. analogous traits d. monophyletic groups
Using the cladogram below, answer the following question. The wolf, leopard, and domestic cat are all mammals that are meat-eaters with four legs and claws. Why is the wolf not classified with the leopard and domestic cat?
a
Wolves do not have retractable claws.
b
Wolves howl and do not purr.
c
Leopards and domestic cats have fur, while wolves do not.
d
Wolves are technically not mammals.
