Hypercarnivores, or enormous predators, most likely shaped the ecosystem during the Pleistocene epoch. Essentially, packs of these large animals controlled populations of herbivores so to preserve the ancient landscapes and valuable vegetation.
Mineral clues hidden within ancient molten rocks suggest life on the planet arose 300 million years ahead of previous estimates. This changes the way scientists view the Earth following its formation 4.5 billion years ago.
