Evolution

Fly four billion years of ancestry in 3D. Search any living thing — a whale, a mushroom, a T. rex — and watch the rest of the tree fall away to leave its lineage alone. Then press play: 51 real ancestors morph into one another as one continuous animal, from the first cell to today, while the clock counts down and the camera walks the branch. Ten deep-dive stories tell how a whale learned to swim, how a chicken descends from dinosaurs, and how a bat built a wing out of a hand — each with the fossil, the bone or the gene that settled it. A Bones view morphs one forelimb across seven species so you can see the same six bones become an arm, a wing, a flipper and a hoof. A DNA view lets you read a divergence date straight off a protein and check it against the fossils. 636 branches, 100 questions and 8 investigation cases.
