A slight ridge of bone found along the midline sagittal suture of the cranium, which is typically found on H. erectus skulls.
when did Homo erectus appear in the fossil record?
true/false: Homo habilis was an active hunter
Which fossil hominin would have an IMI of 69, like modern humans, and an average brain size of 1000cc?
Homo rudolfensis is so morphologically similar to ________ that they may be regarded as the same species.
The earliest members of the genus Homo have been found to date from:
Australopithecines and Homo habilis were similar to each other in what way?
overall body plan and body size (longer arms adn shorter legs)
A cranial feature of Neandertals in which the occipital bone projects substantially from the skull's posterior
The stone tool culture in which Neandertals produced tools using the Levallois technique
The middle part of the Old Stone Age, associated with Mousterian tools, which Neandertals produced using the Levallois technique
A distinctive method of stone tool production used during the Middle Paleolithic, in which the core was prepared and flakes removed from the surface before the final tool was detached from the core
Refers to the most recent part of the Old Stone Age, associated with early modern Homo sapiens and characterized by finely crafted stone and other types of tools with various functions.
Refers to hardened plaque on teeth; the condition is caused by the minerals from saliva being continually deposited on tooth surfaces.
Dubbed the "Hobbit" for its diminutive size, a possible new species of Homo found in Liang Bua Cave on the Indonesian island of Flores
A condition in which the cranium is abnormally small and the brain is underdeveloped
A dental trait, commonly found among Native Americans and Asians, in which the incisors' posterior aspect has varying degrees of concavity.
The earliest hominin inhabitants of the Americas; they likely migrated from Asia and are associated with the Clovis and Folsom stone tool cultures in North America and comparable stone tool cultures in South America.
Earliest Native American ("Paleoindian") culture of North America; technology known for large, fluted, bifacial stone projectile points used as spear points for big-game hunting
Early Native American (immediately following Clovis) culture of North America; technology known for large, fluted, bifacial projectile points used as spear points for big-game hunting
General term for the large game animals hunted by pre-Holocene and early Holocene humans.
The name first proposed by Ernst Haeckel for the oldest hominin; Dubois later used this name for his first fossil discovery, which later became known as Homo erectus.
An early species of Homo and the likely descendant of H. habilis; the first hominin species to move out of Africa into Asia and Europe.
The culture associated with H. erectus, including handaxes and other types of stone tools; more refined than the earlier Oldowan tools.
The most dominant tool in the Acheulian Complex, characterized by a sharp edge for both cutting and scraping
Hypothesis pertaining to hominin mothers giving birth to a large-brained, large-bodied infant: Owing to the large brain, the birth process requires a wide pelvis, but efficient bipedalism requires a narrow pelvis
