Here, have fun.
The GIF is adapted from an animation in Carl Sagan’s Cosmos. Sagan’s narration helps clarify sticking points; the images that pop up to the side of the central image shows where other species branched off on the way to humans. Needless to say (we hope), the dinosaur depiction shows where the giant lizards branched off, then travels with them for just a bit. The GIF then returns to pre-dino species, and follows the evolution tree through from there — all the way to you and me.
