Prehistoric History

Most scientists believe the evolution of humans has a history nearly as long as life itself. Anatomically modern humans and all other life that has existed on the planet first came about from the single-celled microorganisms that emerged approximately four billion years ago. Through the processes of mutation and natural selection, all forms of life developed, and this continuous lineage of life makes it difficult to say precisely when one species completely separates from another.

The current view of science is that Earth is around 4.6 billion years old. The first four billion years of its development are known as the Precambrian period. For the first billion years or so, there was no life on Earth, and then the first single-celled life-forms, early bacteria and algae, began to emerge. It’s unknown where they came from or even if they originated on this planet at all, but this gradual development continued until suddenly (in relative geological terms), more complex forms of life began to emerge.

The early history of Earth covers such vast stretches of time that years, centuries, and even millennia become virtually meaningless. Instead, paleontologists and scientists who study geochronology divide time into periods and eras.

Learn how fossils teach us about dinosaurs.

Ankylosaurus and other armored dinosaurs were the tanks of the prehistoric world. Sharp spikes and rock-hard plates protected these plant eaters from dangerous predators.

Tyrannosaurus rex and its relatives were fearsome meat eaters and deadly predators. Their strong teeth and jaws could crush bone. Go back to a time when these mighty carnivores walked the earth.

Dinosaurs like Stegosaurus had stiff plates on their bodies. Some used their plates to heat themselves up or cool themselves off. This book takes listeners back to a time when these scaly herbivores walked the earth.

Dinosaurs such as Triceratops had deadly horns, bony frills, and sharp beaks. Some of these powerful plant eaters were so strong, they could knock down trees.

Long-necked dinosaurs like Brachiosaurus looked down on the earth from above the treetops. These mighty plant eaters had long tails, necks, and bodies.

Allosaurus and its relatives were fierce and dangerous predators. Dinosaurs in this group had deadly claws and razor-sharp teeth.

If you think dinosaurs are cool, wait till you learn what covered Earth 430 million years ago. That’s long before dinos even existed. There wasn’t much on land - some really tiny plants and even smaller animals like millipedes and mites. But offshore life was another story. Six-foot-long relatives of modern scorpions roamed the open water, gobbling up smaller creatures. Fish were out there, too. There just weren’t many of them, and they were much different than today’s fish.

From prehistoric times to the 1800s, the Plains or Great Plains were settled by people who migrated from Asia. Around 10,000 years ago, the earliest settlers of America were the Stone Flaked people (Lithic). They chipped rocks to make heads for their spears to hunt food or to make scrapers. The scrapers were for cutting wooden spear handles or for cleaning animal hides to make them soft for wearing. Do you think you could have survived as one of the Great Plains People?
