"Lynch and Granger suggest these bigger-brained humans, dubbed "Boskops", were forgotten by history because their very existence
threatened our egos. With their large prefrontal cortices - the parts of the brain involved in high-level cognitive tasks - the
authors suggest that the Boskops may have been capable of impressive mental feats: "With their perhaps astonishing insights, they
may have become a species of dreamers, with an internal mental life literally beyond anything we can imagine."

Boskop Man was once thought to be a unique and ancient hominid genus. The possible genus was based on a skull discovered in 1913.
The term "Boskop Man" is no longer used by anthropologists.
The first Boskop skull was discovered in 1913 by Frederick FitzSimons; many related subsequent skulls were discovered by other
prominent paleontologists of the time, including Robert Broom, Alexander Galloway, William Pycraft, Sidney Haughton, Raymond Dart,
and others.
The popular science writer Loren Eiseley described them in his book "The Immense Journey":
... ten thousand years ago. The man of the future, with the big brain, the small teeth.... He lived in Africa. His brain was bigger
than your brain. His face was straight and small, almost a childs face. When the skull is studied in projection and ratios
computed, we find that these fossil South African folk, generally called Boskop or Boskopoids after the site of first discovery,
have the amazing cranium-to-face ratio of almost five to one. In Europeans it is about three to one. This figure is a marked
indication of the degree to which face size had been modernized and subordinated to brain growth.
