Anth 151 Exam 2 || 100% VERIFIED!!
Gracile vs. Robust Australopiths correct answers 4.2+ mya - 1 mya
Adapted for habitual bipedalism, earliest hands adapted to tree climbing
Skull is still ape-like: brain size comparable to chimps
400-550 cubic centimeters
Graciles: smaller, our lineage
Robusts: larger offshoot that went extinct
At least 7 different species
Homo Habilis correct answers 2.4 - 1.4 mya
Cranial capacity range is 600 - 800 cc
Bigger brains: ancestor for Homo lineage
Can be classified into 2 or 3 species
3 Paleolithic ages
used Oldowan tools
Homo Erectus correct answers 1.9 mya - 300,000 ya
Brain size (800-1200 cc), smaller teeth, prognathic and no chin, 5-6ft tall, relatively hairless.
1st hominin found outside Africa (left around 1.8-1.9 mya)
Homo neandertalensis (Neandertals) correct answers 250,000 - 35,000 ya.
Europe and Middle East
Large cranial capacity (1500-1600 cc)
Occipital bun - alien back head
Large brow ridges, face pinched forward, no chin or forehead
Olduwan correct answers oldest stone tool tradition, flakes and pebble chopping tools
primarily made. Commonly associated with homo habilis
Acheulian correct answers Stone tools that featured a high degree of symmetry, mainly
including hand axes. Commonly associated with homo Erectus
Blade technology correct answers tools commonly associated with homo sapiens
trends in hominin evolution correct answers Cranial cap. gets bigger, definition of the chin,
smaller mandible, smaller sagittal crest
Hypotheses for Bipedality correct answers Gather and transport food
Mothers carry infants: loss of body hair, child can't grab hair
Reach food on trees and branches too flimsy to climb
Energy efficient locomotion - allowed them to travel far without tiring
Better Vision on savannah
Stereoscopic vision correct answers eyes in front adding depth perception
Composite tools correct answers A tool made of several pieces. For example, a prehistoric
knife typically included a handle or shaft, a chipped stone blade, and binding materials such
as glue to hold the blade firmly in place.
