Question

what is true about the whales? whales have arms and legs which allows them to walk on land. whales have evolved over millions of years through sympatric speciation. the whales have never evolved.

Explanation:

Whales are marine mammals. Their ancestors were land - based, but over millions of years through allopatric evolutionary processes, they adapted to an aquatic lifestyle. They lack limbs for terrestrial locomotion and have undergone significant evolutionary changes.

Answer:

None of the above options are correct. Whales are fully - aquatic mammals and do not have functional arms and legs for walking on land. They evolved through allopatric speciation (not sympatric speciation) over millions of years from land - dwelling ancestors. And they have indeed evolved.
