Question

The direct evidence of evolution are

Answer 1

The direct evidence of evolution can be the knowledge of lines of descent or actual specimens showing the gradual transition from one form to another. Fossils usually provide this evidence. Several lines of evidence are used to show the evolution of the organisms can be fossil evidence, biogeographical evidence, and anatomical evidence.

Complete answer: Moeritherium is an extinct genus that contains a group of primitive proboscideans. These are prehistoric mammals that are related to the modern-day elephant and, somewhat more distantly, sea cows, and hyraxes. These organisms existed during the Eocene era.
Moeritherium is extinct mammals. These are one of the very first groups of mammals that were present in the prehistoric epoch. They are also considered to be the distant relatives of present-day elephants. A few of their features possess remarkable similarities to modern-day elephants. Therefore, they are considered to be direct evidence of the evolution of modern elephants and other related animals.
So, the correct answer is option C.
Additional Information:
Moeritherium was round and semi-aquatic mammals with short and stubby legs which existed about 37-35 million years ago. Moeritherium was smaller than proboscideans. Their height was only 70 centimeters (2.3 ft) at the shoulder and they weighed around 235 kilograms (518 lb). Their teeth shape suggests the fact that they used to eat soft water vegetation.

Note: Several species of other primitive proboscideans existed during the Eocene period such as Phiomia and Palaeomastodon which looked relatively more like modern elephants. Moeritherium is a side branch of the proboscidean family which have evolved to resemble other rotund semi-aquatic mammals like pigs, tapirs, and hippos.
