from Pangaea to the Present
Pangaea - 240 million years ago, near the end of the Paleozoic Era, all continents were gathered in a single land mass, the supercontinent Pangaea.
South America isolated - by the end of the Mesozoic Era, South America was isolated from all other continents (but early in the Cenozoic, monkeys would raft in from nearby Africa to establish primate lineages in South America).
Atlantic Ocean growing - by the mid Cenozoic (end of the Eocene Epoch), the young Atlantic Ocean was widening, and North America's land connection to Europe via Greenland and Scandinavia was nearly severed. India had long-since broken away from Antarctica and was approaching Asia, where its collision would raise the Himalaya Mountains. (Continents in mid Cenozoic are shown in green).
