"A joint statement of IAP by
68 national and international science academies lists as established scientific fact that Earth is approximately 4.6 billion years old and has undergone continual change; that life, according to the evidence of earliest fossils, appeared on Earth at least 3.8 billion years ago and has subsequently taken many forms, all of which continue to evolve; and that the genetic code of all organisms living today, including humans, clearly indicates their common primordial origin"

Evidence of Evolution
Scientists have discovered a wealth of evidence concerning human evolution, and this evidence comes in many forms. Thousands of human fossils enable researchers and students to study the changes that occurred in brain and body size, locomotion, diet, and other aspects regarding the way of life of early human species over the past 6 million years. Millions of stone tools, figurines and paintings, footprints, and other traces of human behavior in the prehistoric record tell about where and how early humans lived and when certain technological innovations were invented. Study of human genetics show how closely related we are to other primates – in fact, how connected we are with all other organisms – and can indicate the prehistoric migrations of our species, Homo sapiens, all over the world. Advances in the dating of fossils and artifacts help determine the age of those remains, which contributes to the big picture of when different milestones in becoming human evolved.
Exciting scientific discoveries continually add to the broader and deeper public knowledge of human evolution. Find out about the latest evidence in our What’s Hot in Human Origins section.
Behavior
Explore the evidence of early human behavior—from ancient footprints to stone tools and the earliest symbols and art – along with similarities and differences in the behavior of other primate species.
3D Collection
Explore our 3D collection of fossils and artifacts.
Human Fossils
From skeletons to teeth, early human fossils have been found of more than 6,000 individuals. Look into our digital 3-D collection and learn about fossil human species.
Genetics
Our genes offer evidence of how closely we are related to one another – and of our species’ connection with all other organisms.
Dating
The layers that contain fossils and archeological clues can be dated by more than a dozen techniques that use the basic principles of physics, chemistry, and Earth sciences. Some techniques can even estimate the age of the ancient teeth and bones directly. Advances in dating have made human evolution very exciting!

One Species, Living Worldwide
The billions of human beings living today all belong to one species: Homo sapiens.
As in all species, there is variation among individual human beings, from size and shape to skin tone and eye color. But we are much more alike than we are different. We are, in fact, remarkably similar. The DNA of all human beings living today is 99.9% alike.
We all have roots extending back 200,000 years to the emergence of the first modern humans in Africa, and back more than 6 million years to the evolution of the earliest human species in Africa. This amazing story of adaptation and survival is written in the language of our genes, in every cell of our bodies—as well as in the fossil and behavioral evidence.
This ancient heritage is yours.
Explore the origins of modern humans in Africa about 200,000 years ago and celebrate our species’ epic journey around the world in this video: "One Species, Living Worldwide."

New Research Confirms 'Out Of Africa' Theory Of Human Evolution
Homo sapiens originated in Africa 150,000 years ago and began to migrate 55,000 to 60,000 years ago. It is thought he arrived in Australia around 45,000 years before present (BP). Australia was, at the time, already colonised by homo erectus. This dispersal, from Africa to Australia through Arabia, Asia and the Malay peninsula, could have occurred at a rate of 1km per year.

DNA Agrees With All the Other Science: Darwin Was Right
Molecular biologist Sean Carroll shows how evolution happens, one snippet of DNA at a time
One of the great triumphs of modern evolutionary science, evo devo addresses many of the key questions that were unanswerable when Charles Darwin published On the Origin of Species in 1859, and Carroll has become a leader in this nascent field. Now a professor of molecular biology and genetics at the University of Wisconsin, he continues to decode the genes that control life’s physical forms and to explore how mutations in those genes drive evolutionary change. These days, Carroll also devotes increasing energy to telling the public about his field’s remarkable discoveries through a series of books—Endless Forms Most Beautiful, The Making of the Fittest, and the brand-new Remarkable Creatures. He spoke with DISCOVER senior editor Pamela Weintraub about what his work has taught him about Darwin, the nature of evolution, and how life really works.
It has been 150 years since Charles Darwin proposed his theory of evolution in On the Origin of Species, yet in some ways the concept of evolution seems more controversial than ever today. Why do you think that is?
It is a cultural issue, not a scientific one. On the science side our confidence grows yearly because we see independent lines of evidence converge. What we’ve learned from the fossil record is confirmed by the DNA record and confirmed again by embryology. But people have been raised to disbelieve evolution and to hold other ideas more precious than this knowledge. At the same time, we routinely rely on DNA to convict and exonerate criminals. We rely on DNA science for things like paternity. We rely on DNA science in the clinic to weigh our disease risks or maybe even to look at prognoses for things like cancer. DNA science surrounds us, but in this one realm we seem unwilling to accept its facts. Juries are willing to put people to death based upon the variations in DNA, but they’re not willing to understand the mechanism that creates that variation and shapes what makes humans different from other things. It’s a blindness. I think this is a phase that we’ll eventually get through. Other countries have come to peace with DNA. I don’t know how many decades or centuries it’s going to take us.

Hundreds of Human Genes Still Evolving
A comprehensive scan of the human genome finds that hundreds of our genes have undergone positive natural selection during the past 10,000 years of human evolution.
