Meganthropus
A race of pre-historic hominids has been labeled "meganthropus" by anthropologists. These relatives of man were hypothetically between 7 and 12 feet tall.
It was once theorized that Meganthropus was a descendant of Gigantopithecus, and gave rise to Pithecanthropus, and then modern Asians. This hypothesis, part of the multi-regional theory of human evolution, has been largely discarded.
Some scholars have speculated that the the fossil finds of Meganthropus are merely the males of Homo erectus, the alleged large size and robusticity being only due to an earlier assumption that the females were males . The majority of scientists however, believe that Meganthropus is a relative of Homo erectus, and that while it is related to Homo erectus, it represents an entirely distinct species."
