what morpholoical features do whales have that woule suggest whales are more closely reltaed to humans than fish

1. mammary glands

2. vertebral column

3. four limbs  

Explanation:

Whales and humans have many more detailed features in common (homologies) than do whales and fish because whales and humans share a most recent common ancestor. Whales and humans are mammals (Class Mammalia), whereas fish are not mammals. First, both whales and humans have mammary glands: whales have mammary glands on the chest and stomach (like other mammals). Second, nearly all mammals have a vertebral column composed of 7 cervical vertebrae (humans and whales are not an exception to this rule). Like other mammals, whales have four limbs: although whales are adapted to live underwater, they evolved from a terrestrial mammal ancestor that once walked on four legs (about 50 million years ago).

answer: i cant find your answer. do u have another way i can answer it for you : )

explanation:

he forelimbs below belong to four species that descended in a direct line from the ancestral mammal shown above. of the four descendants shown, which species most likely appeared earliest in evolutionary history?
