It’s based on the Law of Superposition, which states that the bottom layers of a rock formation are older than the top layers.
Radiocarbon dating is an important process that scientists use to help them understand the age of fossils and other types of objects that are old. A key advancement in radiocarbon dating was made when scientists developed a process of dating using isotopes of Carbon instead of Carbon. This process has made it possible to date fossils much more precisely, and has enhanced our understanding of the past.

During the geological timescale, we have found five uniquely large mass extinction events during which significant events like asteroid impacts and volcanic eruptions caused widespread extinctions over relatively short periods of time.
Scientists are saying we may be entering our sixth mass extinction, which is driven mostly by human activity. The interconnected system that we depend on if we lose one species, how does that impact the whole system?
What if we lose thousands? Help your students understand the gravity of extinction with these classroom resources.
Extinction
Extinction is when a species disappears. Each year, millions of species go extinct. Extinction events are typically rare but sometimes occur at the rates of hundreds or even thousands of species per year. This book tells you how to help stop extinction in its tracks.
We may be in the middle of our sixth mass extinction event driven largely by human activity. The Earth is dependent on an interconnected system. If we lose one species, how will that impact the whole system?
What if we lose hundreds? You can teach your students about the importance of protecting the world’s natural habitats with this classroom resource. Human Origins When did humans evolve? Humans have been searching for the answer to this question since Darwin first proposed the concept of evolution in the mid-19th century.
We’ve had religious leaders, such as the Bible, as well as scientists, such as Charles Darwin and Alfred Russel Wallace, who’ve attempted to explain where humans came from, using science and their imaginations.
Then, Mary and Louis Leaky explored the fossil record to see if they could piece together the story of humans. Science and archaeology are still doing research today. Use these materials in your classroom to teach your students about the origins of the homo sapien. How Long Do Birds Live

Human Origins
Humans are very curious, as you’ll learn in this book, which explores the evolution of our human species and how we came about. We were originally apes who evolved into humans. Many questions remain unanswered, but we are on the right track to knowing where we came from.
The Leaky family explored the fossil record to piece together the story of humans. Evolutionary science and archaeology continue to this day. You can use these resources in your classroom to teach your students about the origins of the human species.
