Fossilized footprints from Tanzania around 3.5 mya were likely made by what species
australopithecus afarensis
T/F a narrow, long cyclinder shaped pelvis is a feature associated with bipedal locomotion
FALSE
what does collected food mean
food that is gathered from the wild
the earliest oldowan tools in East Africa date to approximately how many mya
2.6
what species is hypothesized to have potentially buried their dead in caves
homo naledi
what species is the Peking Man
homo erectus
fossils are formed when
bone is mineralized through natural processes
what is the correct order of these time periods: pliocene, miocene, holocene, pleistocene
most recent: holocene
pleistocene
pliocene
oldest: miocene
what species is the Taung Child
australopithecus africanus
T/F bipedalism may have evolved because it allowed hominins to keep cool in savanna environments
TRUE
Imagine you have found the skull of a hominin with an ape-size brain, sagittal crest, very large molars, and large cheekbones. Based on this information, this is most likely a specimen of
paranthropus
what are three fossil candidates for the first hominins
sahelanthropus, orrorin, adripithecus
why is ardipithecus apelike
because it had grasping toes
orrorin tugenensis is identified as a possible hominin on the basis of what evidence
the femur
what is an adaptation of the foot for human bipedality
a stiff, arched foot
isotopes are made of the smallest unit of matter called
atoms
isotopes differ in their number of
neutrons
T/F Longer childhoods allow for learning complex skills required for obtaining high-nutrient foods.
TRUE
what is food that comes from things that do not move but are protected in some way requiring some level of processing before they can be eaten
extracted food
which hominin dominated Europe around 400,000 years ago evolving into Neanderthals
homo heidelbergensis
what is the law of lateral continuity
even when layers of rock are found super far apart, the layers are aged continuously and the approximate age can be found
how many mya did the last common ancestor of chimps and humans live
7 - 5 mya
T/F australopithecus afarensis was not sexually dimorphic
FALSE lucy was dimorphic
what is different about biped femurs
they have a valgus angle
T/F neanderthals and anatomically modern humans in the middle east lived side by side for thousands of years
TRUE
what is taphonomy
the study of what happened to an organism after it died
T/F its likely that the genus homo evolved from the neanderthals
FALSE its likely they evolved from one of the later australopithecines
