Module 2 Flashcards
The primary biological component of humans that
allowed for culture is the developed brain. It has the
necessary parts for facilitating pertinent skills such
speaking, touching, feeling, seeing, and smelling.
Our thinking capacity
-the vocal tract acts as the mechanism by which sounds are produced and reproduced to transmit ideas and values
-traditional scientific belief pegs the development of
language at 100 000 years ago, making it an exclusive trait
to modern human.
Our speaking capacity
_______ argued that the origin of language may be
rooted as far back as 500 000 years ago, based on the
discovered fragment of Homo heidelbergensis (hyoid bone
which is crucial for speaking as it supports the root tongue —
same with homo neanderthalensis)

Two types of grips
- Power Grip
- Precision Grip
- enables humans to wrap the thumb and fingers on object; it became the cornerstone of our
capacity to hold tools firmly for hunting and other
activities.
Power Grip
- enables humans to hold and pick objects steadily using their fingers. This capacity is
crucial in tool-making activities.
Precision Grip
Primates have two forms of locomotion:
- Bipedalism
- Quadropedalism
— is the capacity to walk and stand on two
Bipedalism
- uses all four limbs
Quadropedalism
- practiced the crudest methods of toolmaking
Australopithecines
-stone-tool industry
-characterized by use of “hand water-worn creek
cobles made out of volcanic rock (used to butcher
large animals)
The Oldowan Industry
— a process involving the
systematic collision produces a core tool (used for
general purpose) and the flake tool (used as a
knife)
Percussion Flaking
— supported the existence of oldowan industry
when Mary and louis Leakey at Olduvai Gorge, Tanzania,
which was dated at 2.6 million years ago.
Homo habilis
— acquired the industry after migration within
1.9 -1.8 mya
Homo erectus
- a period of which stone implements were used in multiple activities such as light chopping of wood, digging up roots and bulbs, butchering animals, and cracking nuts and small bones.
