Fossils provide a record of life on Earth from as long as 1 billion years ago, showing how organisms, animals and plants have changed over time. These records can be dated, so they are a physical representation of evolution, such as the way that ancient fish developed a bone in their jaw over time.Know More
According to BioLogos, fossils originating from about 1 billion years ago show that the earliest life on the planet consisted of organisms that were single-celled. The fossils from about half a billion years later show that those single cells had developed into organisms with multiple cells. In other words, the fossils show that organisms evolved over a long period of time, moving from simpler life to more complex life. This pattern continued throughout history, as life forms became more and more complex.
Evolution does not go in a single line, evolving from one form of life to the next. In fact, according to the Smithsonian website, homo sapiens evolved in a large family of other human species, although homo sapiens (the species of humans on the planet now) were the only species to survive.Learn more about Dinosaurs
Dinosaurs come from the evolution of early primitive organisms approximately 230 million years ago and it is unknown why these organisms evolved into dinosaurs. Scientists have been able to trace dinosaurs back 228 million years ago to one of the first species known as the "eoraptor" that was the size of a dog and was carnivorous.Full Answer >
The Tyrannosaurus rex was a carnivore and one of the largest meat-eating dinosaurs on Earth. It could consume nearly 500 pounds of meat in a single bite. The term "tyrannosaurus" means tyrant lizard.Full Answer >
Dinosaurs lived on Earth for about 175 million years, until they were entirely wiped out by the K-T extinction event at the end of the Cretaceous Period. They lived during the Mesozoic Era, and examples of dinosaurs can be found in all three periods of that era.Full Answer >
Fossils are important in understanding the history of the world because they provide physical evidence of animals and plants that lived in the past. Through their discovery, paleontologists uncover new ideas about former life on earth.Full Answer >
