ANTH 4310: Cognitive Evolution Final
| Question | Answer |
|---|---|
| What is a hominin? | A hominin is a species that finally ended with Homo sapiens, the species that are included are authrolopithocines, H. habilis, H. erectus, H. heidelbergensis, Neandertals and h. sapiens. |
| Australopithecus afarensis | Ape like hominin, that was the first to come down from the trees |
| Australopithecus afarensis dates and habitat | 5- 2.5 mya, trees and ground lived in grasslands and woodlands around 2.8 mya |
| Australopithecus afarensis: brain size, EQ, and endocasts | Brain size is 375-500 cc, EQ is 2.2, and the endocasts shows the lunate sulcus moved more to the back |
| Australopithecus afarensis: sexual dimorphism | decrease in sexual dimorphism |
| Australopithecus afarensis: bipedal apes | had some capability for bipedalness |
| Homo habilis | also known as the handy man, used mode I tools |
| Homo habilis background | dates include 2.5-1.5 mya, mainly lived in the savanah of africa, there was some expansion, EQ is 3.1 |
| Homo habilis anatomy | brain size is roughly 550-775 cc, and they were somewhat upright |
| Homo habilis adaptive niche | scavenged for food, possible stalked leopards and used a decoy to gain food. |
| Homo habilis and stone knapping | utilitzed mode I tools in the beginning, stone hammers, cores/choppers, and some flake tools |
| Stout's PET | stone tool making is a motor skill that is learned over time after a while the parietals lobes do not light up |
| Kanzi | used stones tools to gain access to a drink used his own method to make a flake |
| Cognitive basis | provided a small expansion of the parietal lobes, provided better access to the acquisition of food. |
| stone tools at Lokalalei | the stone tools could be refitted to make the core, roughly 24 flakes to make the core |
| Action-level imitation | Stone napping is an action-level imitation learning the more the process is done the better someone knows about it |
| Olduvai Gorge FLK | stone tools and animals bones were found at the site, roughly 2200 stone tools were found, including hammers, cores, and flakes. |
| The Scavenging hypothesis | May people believe that Homo habilis scavenged for their food the may have used deception, spatial mapping, or decoys. |
| Homo erectus | first hominin that was able to use and control fire, used mode II tools |
| Nariokotome | site at Lake Turkana, found an 11 year old male, the body was built for running. |
| Homo erectus Background | lived 1.5 mya to 100,000 ya? brain size is roughly 950 cc, populated most of the known world. |
| Acheulean | almond shaped hand axe used handaxes and cleavers |
| Homo erectus and fire | first species to control fire |
| Homo erectus and Handaxes, sexual selections | Sexy handaxes hypothesis, bigger the knapped axe the more sexual potential |
| Homo erectus and ground sleeping | fire warded off preditors |
| Brain gut trade off | the longer the gut the smaller the brain, the larger the brain the smaller the gut. |
| Language | Index: the physical representation, icon: something that stands for something, symbol: words that describe something. |
| Spatial Cognition | stone knapping, guided by procedural memory, this is largely implicit, non symbolic, coordinated shape/spatial info, tools index of past and future, knapping for tech and social reasons. |
