Answer 2

Answer:

Monotremes are oldest, but Bow Head Whales are oldest living mammal.

Explanation:

Monotremes, which include the platypus and echidnas, are the oldest mammals in the world. They are one of the three main groups of mammals and their prehistoric ancestors appeared about 220 million years ago in the fossil record. The duck-billed platypus and a few species of echidnas are the only existing examples of monotremes left on Earth.

All monotremes are indigenous to Australia and New Guinea but there is evidence that they were more widespread. One of the most notable characteristics about monotremes is that they are the only egg-laying mammals left on the planet today.

Some confirmed sources estimate bowhead whales to have lived at least to 211 years of age, making them the oldest mammals.
