One Tree of Life

One Tree is a hand-built map of life on Earth — four billion years deep, from you at the top of time down to the last ancestor every living thing shares. Two ways to travel it: WALK THE TREE Begin as Homo sapiens and walk back down your own branch, meeting your ancestors one divergence at a time — then climb back up to meet their other children. Every fork asks what separated the branches. Reconstructed ancestors are shown as exactly that: inferred from their living descendants, never passed off as photographs. Play to trace your shared ancestry with a lemur, an octopus or an oak, or take the quiz and name who you are from a single clue. TOUR DEEP TIME A rotating globe and a radial clade map carry you from the Big Bang to now. Scrub the timeline and watch the tree of life grow outward from a single cell — new lineages branching to the rim as time moves toward the present — each stop pinned where its trace was actually found. Built on one principle: the wonder should be earned. Every date sits in the geological period it actually happened in, every ancestor is older than its descendants, and where the science is uncertain the uncertainty is shown, not hidden. No accounts, no ads, no tracking — and it all works offline. Homo sapiens is the final 0.008% of the story on this map. Come and see the rest.
