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).

Deepika Gautam 3 years, 10 months 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.

Sia ? 3 years, 10 months ago

All over the world animals and people spend a significant amount of time and energy providing shelter for themselves. Animals use many kinds of shelters. Foxes burrow into the ground. Beavers build mud-and-stick lodges in shallow streams. Some bears hibernate through the winter in the hollows of rocky cliffs or in holes in the ground. Apes build themselves nests of twigs in trees for protection while they sleep.

Human shelters also take many forms. People may build huts of mud and branches roofed with leaves. They may live in houses of wood, brick, or stone, or in huge apartment buildings of steel, concrete, and glass. They may use movable shelters such as tents, houseboats, and trailers or even recreational vehicles (RVs).
