Comparative Cognition Flashcards
indicators of developed cognition
use of tools
cogniton of birds resembles that of
primates
cogniton of birds resembles that of
primates
first use of tools by humans
Palaeothlic
Which humans understood how to utulise platform depth and exterior platform angle?
H heidelbergensis, H eretctus, neanderthals
Lower Palaeothlic tools
Chopper stones
flakes
What happened to tools as the paleothic age progressed?
tools became sharper
the correlation of technological innervation with what characteristic is poorly understood?
Brain size
the correlation of technological innervation with what characteristic is poorly understood?
Brain size
what aspect of the cortex is thought to contribute to cognition?
gyri
why are human brains not as expected?
larger than apes, neocortex larger than expected, more white matter
Encephalization quotient
ratio between observed and predicted brain mass for an animal of a given size
human cognitive ability may be explained by
relative size of cortical areas: increased relative size of neocortex. more neurons
how do primates and rodents differ in brain structure?
primates alwaysc oncentrate larger numbers of neurons in the brain than rodents of a similar, or even larger,brain size, especially in the cerebral cortex
evolution of tools hows what progression?
refined sharpening
when did length of flint edge increase relative to its size
pleistocene
flint thickness at its origin:
platform depth
exterior platoform angle:
angle between the surface being hit and the surface of stone core being used to make the flake
how can flakes be made with sharper edges?
increasing the exterior platform angle
where can middle stone age tools be found?
Jebel Irhoud
