|
morphological |
pertaining to the form and structure of organisms |
|
|
habitual bipedalism |
bipedal locomotion as the form of locomotion shown by hominins most of the time |
|
|
obligate bipedalism |
bipedalism as the only form of hominin terrestrial locomotion Since major anatomical changes in the spine, pelvis, and lower limb are required for bipedal locomotion, once hominins adopted this mode of locomotion, other forms of locomotion on the ground became impossible. |
|
|
Sterkfontein |
(sterk'-fawn-tane) South Africa; Clarke and Tobias, 1995 Fossil evidence of early hominin foot structure |
|
|
honing complex |
The shearing of a large upper canine with the first lower premolar, with the the wear leading to honing of the surfaces of both teeth. This anatomical pattern is typical of most Old World anthropoids but is mostly absent in hominins. |
|
|
Aramis |
(air-ah-miss) discover site of a very large and significant assemblage of fossil hominins in Ethiopia's Middle Awash region. |
|
|
australopiths |
a colloquial name referring to a diverse group of Plio-Pleistocene African hominins Australopiths are the most abundant and widely distributed of all early hominins and are also the most completely studied. |
|
|
sectorial |
adapted for cutting or shearing; among primates, this term refers to the compressed (side-to-side) first lower premolar, which functions as a shearing surface with the upper canine. |
|
|
sagittal crest |
a ridge of bone that runs down the middle of the cranium like a short Mohawk This serves as the attachment for the large temporal muscles, indicating strong chewing. |
|
|
endocast |
a solid impression of the inside of the skull vault, often preserving details relating to the size and surface features of the brain |
|
|
Plio-Pleistocene |
pertaining to the Pliocene and first half of the Pleistocene, a time range of 5 to 1 mya For this time period, numerous fossil hominins have been found in Africa. |
