The earliest ancestors of primates evolve from small, tree-dwelling mammals.
Primates split into two major branches: the monkeys of the Americas and those of Africa/Asia.
The ancestors of gorillas, chimpanzees, bonobos and humans develop separately from other apes.
Around this time, the evolutionary line leading to humans splits off from that of chimpanzees and bonobos.
An early hominid that walked upright, discovered as the famous fossil 'Lucy' in Ethiopia.
This 'handy man' creates the first deliberately manufactured stone tools.
Homo erectus learns to make and use fire, and is the first hominid to migrate out of Africa.
Anatomically modern humans appear in Africa, with a larger brain and more complex behaviour.
An explosion of symbolic thought, language and art fundamentally changes humankind.
Groups of Homo sapiens leave the African continent and spread toward the Middle East, Asia and later Europe.
Humans begin decorating caves with paintings of animals, handprints and abstract symbols, a sign of advanced symbolic thinking.
Humans begin taming wolves, leading to the first domesticated animals and a new bond between humans and animals.
Groups of hunter-gatherers cross the Bering land bridge from Siberia to Alaska and spread across North and South America.
The earth slowly warms, ice caps retreat and new habitats emerge for humans and animals.
Humans begin growing crops and domesticating animals, leading to permanent settlements.
In Mesopotamia, the first urban settlements arise, such as Uruk, in which thousands of people live together.
In Sumer, cuneiform script is developed, the first form of written communication.
The use of bronze tools and weapons spreads, and the first great empires such as Egypt and Babylonia arise.
Greco-Roman civilisation flourishes, with major developments in philosophy, science, law and democracy.
The Western Roman Empire collapses after centuries of political instability and invasions by Germanic peoples.
In the Middle East, a civilization flourishes that preserves, translates and further develops the science, philosophy and medicine of antiquity.
Mongol armies led by Hulagu Khan destroy Baghdad, the centre of the Islamic Golden Age.
A devastating pandemic of the plague spreads via trade routes from Asia to Europe and the Middle East.
Scholars and artists in Italian city-states rediscover classical texts and lay the foundation for the Renaissance.
A cultural and intellectual revival in Europe leads to innovations in art, science and philosophy.
An intellectual movement that placed reason, science and individual freedom at the centre of thinking about humanity and society.
Innovations in farming techniques and crop rotation drastically increased food production, enabling population growth.
Political upheavals that brought down monarchical power and spread ideals of freedom, equality and civil rights.
Machines, steam power and factories transform humanity from agrarian into industrial societies.
Electricity and telecommunications drastically change daily life.
Inventions such as the automobile and the airplane profoundly change transport and warfare.
Discoveries in physics and chemistry, together with Fordist production methods, transform society and industry.
Large-scale conflicts accelerate technological development and reveal humanity's destructive power.
Computers and the internet connect people worldwide and fundamentally change society and the economy.
The introduction of smartphones and social networks changes the way people communicate, share information and interact with each other worldwide.
Artificial intelligence develops from an experimental technology into an omnipresent force that transforms industries, science and daily life.
Under pressure from the climate crisis, humanity accelerates the shift to renewable energy sources and develops new technologies to combat global warming.
Scientists unravel the human genome and begin to redesign life at the molecular level.
Genetically enhanced humans become socially accepted and regulated by international treaties.
Scientists create the first AGI that matches or exceeds human intelligence in nearly all areas.
First experimental technologies enabling people to communicate with computers and each other via direct brain signals, as a precursor to full cyborg technology.
speculative: genetic manipulation and artificial intelligence merge with the human body and brain
The first permanent, self-sufficient settlements on Mars achieve full independence from Earth.
Humanity develops shared consciousness networks in which individual minds can be connected to one another.
Speculative: by the year 6000, humanity has spread across multiple planets and evolved into a new species.
Humanity, by now a post-human species with widely diverging genetic and technological variants, begins the systematic exploration and colonization of star systems beyond the solar system.
A turning point at which the majority of the post-human population decides to fully integrate their consciousness with digital, distributed networks, leading to a new form of collective intelligence.
A network of connected consciousness nodes stretches across thousands of star systems, formed by humans, their descendants and allied intelligences.
Due to continental drift and the separation of Africa and South America, isolated populations of primates arose. This led to the separation between the platyrrhini (New World monkeys, with flat noses) in South America and the catarrhini (Old World monkeys, with narrow nostrils) in Africa and Asia. This latter group would eventually contain the ancestors of apes and humans.
