Mammals evolved from a group of reptiles called the synapsids. These reptiles arose during the Pennsylvanian Period (310 to 275 million years ago). A branch of the synapsids called the therapsids appeared by the middle of the Permian Period (275 to 225 million years ago).

The earliest known mammals were the morganucodontids, tiny shrew-size creatures that lived in the shadows of the dinosaurs 210 million years ago. They were one of several different mammal lineages that emerged around that time. All living mammals today, including us, descend from the one line that survived.

The process by which the uppermost layer of the earth ( which is known as soil) is damaged by the natural forces like wind and water is known as soil erosion

Deepika Gautam 4 years, 1 month ago

Soil erosion is the displacement of the upper layer of soil; it is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice, snow, air, plants, animals, and humans.

Unlike fleas, grasshoppers rely on muscles and tendons to make their jumps possible. They are capable of jumping over 20 times their body length, which means a mature grasshopper can leap forward about 40 inches.
