Pine trees are gymnosperms, the oldest of the seed bearing plants. They evolved during the Paleozoic Era, approximately 416 million years ago. During that era, the continents were still fastened together as one continent, called Pangaea. It was not until the Triassic Period, 250 million years ago, that the continents began to break up and drift apart.
