African roots.
A world of difference.
Our species emerged in Africa. Across thousands of generations, movement, isolation, adaptation, and reunion shaped the people we are today.
The updated “Out of Africa” framework is strongly supported. Exactly how our African ancestors became Homo sapiens remains an open question. [1]

Select an era. Explore the evidence.Generalized present-day coastlines. Paths are illustrative corridors, not reconstructed tracks. Dates are approximate; the map is cumulative.
WHAT “OUT OF AFRICA” MEANS TODAY
One species, with a braided history.
Anatomically modern humans did not appear fully formed on a single day. Fossils show a mosaic of features, while genomes reveal populations that separated and reconnected. Most ancestry in living people outside Africa traces to a major later expansion, with smaller contributions from Neanderthals and Denisovans. [1] [2]
Well supportedAfrican origins; shared ancestry; interbreeding with archaic humans.
Still debatedWhere within Africa; the structure of ancestral populations; exact routes and dates.
02 / IDEAS CHANGE WITH EVIDENCE
How the story changed.
Choose a model to see what it proposes and where it stands today. These are historical and competing explanations, not equally supported alternatives.
Conceptual ancestry diagram. Lines show descent or gene flow, not racial groups. Time runs downward; spacing is not to scale.
2026 / THE EVIDENCE KEEPS GROWING
Deeper roots, missing diversity. Moroccan fossils dated to about 773,000 years ago illuminate a lineage near the root of H. sapiens, rather than proving modern humans existed then. Ancient southern African genomes reveal variation not fully represented in living populations. Neither result settles a single birthplace. [8] [9]
03 / WHY WE DIFFER
Variation has a history.
Race is not a family tree.
Our ancestors were already diverse within Africa, which still holds the greatest human genetic diversity. Migration reshaped that diversity; it did not begin it. [9]
Visible differences are real.
Fixed biological races are not.
Skin pigmentation, hair form, and other traits have different, overlapping histories. Ancestry can be studied genetically, but it does not divide humanity into clean, timeless racial boxes. Racial categories are social classifications that change across places and periods. [11]
Similar skin tones can evolve in distantly related populations. No living population is more evolved, or an unchanged version of our ancestors. Race still has real social consequences, including through racism.

How to read this atlas
Dates refer to years before present and are rounded for teaching. The time slider selects six unequal narrative intervals, not equal units of time. Markers identify illustrative regions or named evidence sites, not the location of every ancestor. Arrows do not imply a single migration, precise route, or total replacement. Diagrams and variation plots are conceptual, not measured datasets. Modern coastlines omit ancient shorelines and land bridges. Many migrations within Africa, return migrations, and later movements are not individually mapped. This atlas concerns the origins and dispersal of Homo sapiens, not the earliest exits of other Homo species.
