Our own species, which arose in Africa about 300,000 years ago and is the only surviving human species.
See it on the Life map →What happened
Homo sapiens has a rounded braincase, a small face tucked beneath it, a chin and a lighter skeleton than earlier humans. The oldest fossils come from Jebel Irhoud, Morocco (about 315,000 years), and Omo Kibish, Ethiopia (at least 233,000). Early sapiens lived across Africa in many loosely connected populations. From about 70,000–50,000 years ago they spread worldwide, absorbing some Neanderthal and Denisovan DNA. Today there are over 8 billion of us.
Why it matters
Our species alone survived, reached every continent and invented farming and cities; the story of civilization continues in the Curious History map.
The evidence (fossils, genes, rocks)
Fossils, archaeological sites and the genomes of living and ancient people; DNA shows the deepest branches of today's human family tree among African peoples such as the Khoe-San.
Still debated
Did we evolve in one region or across Africa? A 2025 genetic study suggested two populations, separated for over a million years, merged to form us.

Connections (9)
▸Homo heidelbergensis may be the ancestor of Homo sapiensDebated
The connection
In Africa, heidelbergensis-like fossils such as Bodo and Kabwe come before the earliest Homo sapiens. Many researchers think an African population of this kind evolved into our species by about 300,000 years ago, while related populations elsewhere led to Neanderthals and Denisovans.
When and how
Africa, about 600,000–300,000 years ago; Bodo (Ethiopia, about 600,000 years) and Kabwe (Zambia, about 300,000 years).
How sure are we?
DNA puts the split between our line and the Neanderthals' at about 550,000–765,000 years ago, fitting this group's time span. Which fossils are ancestral is uncertain.
Debates and open questions
African fossils are sometimes renamed Homo rhodesiensis or Homo bodoensis. Kabwe, at 300,000 years, may be a cousin that lived alongside early sapiens, not an ancestor.
▸Homo floresiensis ('the hobbit') overlapped in time with Homo sapiensStrong evidence
The connection
The hobbit's bones date to about 100,000–60,000 years ago, and its youngest tools to about 50,000 years ago. Modern humans passed through the Indonesian islands around then on the way to Australia, so the two species may have met; the hobbits then vanish from the record.
When and how
Liang Bua cave, Flores; hobbit traces to about 50,000 years ago, modern humans in the region from about 50,000 years ago or earlier.
How sure are we?
The dates overlap, but no direct evidence of contact has been found, so any interaction is inferred.
Debates and open questions
Whether modern humans or volcanic eruptions caused their end is debated, as is whether Flores legends of small 'Ebu Gogo' people reflect folk memory or pure myth.
▸Jebel Irhoud (Morocco) holds the oldest known fossils of Homo sapiensStrong evidence
The connection
Re-dated in 2017 to about 315,000 years, the Jebel Irhoud skulls have a modern-looking face and teeth but a long, low braincase. They suggest our species' face evolved first and the rounded brain later, pushing back the origin of sapiens by about 100,000 years.
When and how
Jebel Irhoud, Morocco; first fossils found by miners in 1961; new fossils and dates from Jean-Jacques Hublin and Abdelouahed Ben-Ncer's team, published in Nature in 2017.
How sure are we?
Heated flint tools were dated by thermoluminescence and a tooth by electron spin resonance; 3D shape comparisons placed the faces within the modern human range.
Debates and open questions
Whether a modern face on an archaic braincase counts as Homo sapiens is partly a matter of definition; some prefer to call them early relatives or 'proto-sapiens'.
▸Homo sapiens underwent Behavioral modernity (the 'cognitive revolution')Debated
The connection
Homo sapiens existed for some 200,000 years before signs of modern behavior became common: art, beads, complex tools and long-distance exchange. Older views saw a sudden change about 50,000 years ago; newer African finds suggest these abilities built up gradually from much earlier.
When and how
Africa, especially Blombos Cave, South Africa (engraved ochre and beads, about 100,000–75,000 years ago), and Olorgesailie, Kenya (obsidian carried long distances, and pigments, about 320,000 years ago).
How sure are we?
Dated artifacts show symbolic behavior well before 50,000 years, but only here and there. Fossil skulls show brain shape changing over the same long span.
Debates and open questions
Whether the change was biological, such as language-related brain changes, or cultural, as growing populations kept and spread skills, remains debated.
▸Homo sapiens left Africa in Out of Africa: Homo sapiens spreads worldwideStrong evidence
The connection
After a few earlier forays, a small population of Homo sapiens left Africa about 70,000–50,000 years ago and spread across Asia, Australia and Europe. Nearly all people outside Africa descend from this group, which met and interbred with Neanderthals and Denisovans along the way.
When and how
From northeast Africa into Arabia or the Levant, about 70,000–50,000 years ago; earlier forays at Misliya and Skhul–Qafzeh, Israel, about 190,000–90,000 years ago.
How sure are we?
Genetic diversity falls with distance from Africa; mitochondrial and Y-chromosome family trees root in Africa; ancient genomes and Neanderthal DNA segments help date the expansion.
Debates and open questions
Which route was used, and whether an earlier wave around 100,000 years ago left lasting ancestry. Some scholars put the main exit closer to 50,000 years ago.
▸The genus Homo led eventually to Homo sapiensWell established
The connection
Over about 2.5 million years, the Homo lineage grew bigger brains, used more complex tools and spread out of Africa repeatedly. Many Homo species coexisted; Homo sapiens arose from one African branch around 300,000 years ago and is now the only survivor.
When and how
Africa, from about 2.8 million to 300,000 years ago, with side branches across Eurasia and Indonesia.
The evidence
Fossils show the long trend in brain size and body shape; ancient and modern DNA trace our ancestry back to African populations.
Debates and open questions
The exact sequence of ancestors is debated. Our line looks less like a single trunk than a braided stream, with populations splitting and rejoining.
▸Dogs: the first domesticated animal were domesticated from wolves by Homo sapiensWell established
The connection
Dogs were domesticated by ice-age hunter-gatherers of our own species, not by Neanderthals. Wolves that tolerated people may have scavenged around camps, and people may have raised pups. Over generations, tamer animals bred more successfully and changed physically: smaller teeth and skulls, floppy ears, curled tails and, later, extra genes for digesting starch.
When and how
Somewhere in Eurasia, roughly 23,000–15,000 years ago; one leading study points to Siberia, where people and wolves were isolated during the ice-age peak.
The evidence
Ancient DNA from dog and wolf genomes, and dogs buried with people, such as at Bonn-Oberkassel in Germany about 14,200 years ago.
Debates and open questions
Whether people or wolves started the relationship, and whether dogs arose once or in two places, such as East Asia and Europe.
▸Homo sapiens invented Agriculture beginsWell established
The connection
Farming is a sapiens invention: no other human species is known to have farmed. Hunter-gatherers already knew plants intimately, gathering wild grain and managing land with fire. In the Holocene, groups began planting, tending and selecting crops and herds, changing them genetically, and were changed in turn by new diets and diseases.
When and how
Independently in at least 11 regions, including the Fertile Crescent, China, New Guinea, Mesoamerica, the Andes and Africa, from about 11,500 years ago.
The evidence
Archaeological sequences show local foragers becoming farmers; human genomes show farming-linked changes, such as adult milk digestion among herding peoples.
Debates and open questions
In Europe farming spread mainly with migrating farmers, elsewhere by foragers adopting it; why sapiens took it up only after some 290,000 years is still argued.
▸Carl Linnaeus coined the name Homo sapiensWell established
The connection
In the 10th edition of Systema Naturae (1758), Carl Linnaeus placed humans in the animal kingdom among the primates and gave us the scientific name Homo sapiens, Latin for 'wise man'. His two-part naming system is still used for every species.
When and how
Uppsala, Sweden; Systema Naturae, 10th edition, 1758, which zoologists treat as the official starting point for animal names.
The evidence
The published text survives, and the international code for naming animals takes 1758 as its starting date.
Debates and open questions
Linnaeus named no type specimen. In 1959 botanist William Stearn designated Linnaeus himself as the type of Homo sapiens, a choice not everyone accepts.
