How old is human life on earth




















Homo antecessor in western Europe Atapuerca , Spain , closely related to the last common ancestor of Neanderthals, Denisovans and modern humans. Homo sapiens enter Eurasia Greece : first of multiple dispersals out of Africa by humans with early modern traits, including globular braincase and descended larynx facilitating spoken language.

Hunter-gatherer nomads. Homo with mix of archaic-human and Neanderthal traits Nesher Ramla , Israel : stone-tool industry, cooking meat; cultural exchange with humans? Eurasian Homo sapiens co-existing with Homo floresiensis soon extinct and Homo luzonensis , interbreeding with Neanderthals and Denisovans. Anatomically modern humans henceforth the only hominin. Agricultural farming and settlements. BCE Homo neanderthalensis Neanderthal man lived in Europe and southwestern to central Asia but became extinct 40, years ago.

Homo floresiensis the Hobbit evolved in Asia but became extinct 50, years ago. Homo heidelbergensis lived in Europe, China, and parts of Africa but became extinct , years ago. Homo sapiens migrated from East Africa in waves, around 7, years ago the species reached the southern coast of Asia then to Oceania 50, years ago and finally reached Europe forty thousand years ago.

About 20, years ago, the northern Eurasian population migrated to the Americas. Canada and Greenland were inhabited 4, years ago while Polynesia was inhabited 2, years ago. The evolutionary process led to modern humans. Victor Kiprop January 12 in World Facts. Olympic Games History. Southeast Asian Countries. Commonwealth Of Independent States. The conditions of the past have been so varied that there is no stable baseline on which to base what "the past" looked like.

Stories of mass extinctions and the destruction of our major cities are useful tools to put the urgency of our situation in perspective. None of this is inaccurate, and it is critical that the public, and especially those in positions of power, understand the scope of influence our species has had on the planet.

But oftentimes this dialogue leaves out a critical perspective: what we can do to change our behavior and environment to create a positive future.

The story of human evolution features a unique ability to adapt in the face of changing climates, and this will be no different for human-shaped climates of today and the future. With our own growing awareness of how our actions impact the natural world, the question is how best we can shape our actions so that the consequences of our activities are purposeful and positive.

Altering our surroundings is fundamental to human survival. In this light, how may we come to alter the world that we've created in a conscious and productive way? Community and global collaboration, along with innovation, will be the keys to creating a new path for the future of our species and our environment.

By looking at the Anthropocene from a human origins viewpoint, the narrative of our collective humanity and the qualities that unite us as a species with a common origin can give us a sense of communal purpose in developing solutions for the problems of the Anthropocene.

These are some of the many questions that we must answer as we begin to craft the future of the Anthropocene:. Contemplating these questions will help us begin to determine the future of the Anthropocene. The themes of self-determination, community, and action will all be parts of the human-driven innovation for the future of the planet. As we look to the future, we will see not only the planet change, but we may even see changes in ourselves as a species.

We invite you to contemplate: What will it mean to be human in the future of the Anthropocene? Smithsonian Statement on Climate Change. What is the Anthropocene and Are We in It?

As of , humans had built so many dams that nearly six times as much water was held in storage as flowed freely in rivers. A visual representation of the breakdown of geological time. The Anthropocene would come after the Holocene. The sharp upward spike in all of the trends displayed on this graph show how human activity has increased since the Great Acceleration. Human pollution shows the impact of the Anthropocene on many issues. It destroys natural landscapes and poses a critical danger to many animals who may consume or become entangled.

The layers of sediment visible on this hillside in the Rift Valley of southern Kenya illustrate change in the environmental conditions faced by human ancestors around 1 million years ago. These objects found in Africa illustrate the many thousands of clues discovered about human origins, including use of tools and symbols, increasing brain size, and footprints indicating walking upright.
