The break-up of Pangaea, which occurred during the Mesozoic era, had a profound impact on the evolution of life on Earth. As the supercontinent began to separate, new oceans formed and different groups of organisms were isolated from each other, leading to the evolution of many new species. This event also marked the beginning of the formation of the modern continents as we know them today. While the emergence of humans occurred much later in history, during the Quaternary period, the Mesozoic era is still considered a crucial time in the evolution of life on Earth. The Pleistocene extinction and ice age both occurred much later, during the Cenozoic era.
