Most early primates were probably nocturnal, or active at night.Their eyes were bigger and their noses were smaller than those of the ancestral mammals, showing that the primates relied more on sight and less on scent.53 Others compare Gigantopithecus to a full- grown male polar bear: more than 10 feet (3 meters) tall and weighing 1,200 pounds (545 kilograms). Ever since the discovery of Gigantopithecus, people have speculated that small, isolated populations of this giant ape might still be alive.Could encounters with surviving Gigantos be the source of folklore about apemanlike creatures such as Yeti in the Himalayan region and Sasquatch or Bigfoot in North America? For one thing, no proof exists that Yeti and Bigfoot are real.
52 This would make Giganto about 6 feet tall (under 2 meters), with a weight of about 400 pounds (181.6 kilograms).Interestingly, the proportions of its hands—the length of the thumb relative to the fingers—were closer to those of humans than to apes.The scientific jury is still out on whether Proconsul was a true ape.Differences among them suggest that Asia may once have been home to several species of Gigantopithecus, probably related to Siva- pithecus.Estimates of the giant ape’s size cover a broad range.
