Final Part 1 Flashcards
(46 cards)
The study of historic or prehistoric human populations though the analysis of material remains
Archaeology
Studies hominins, their remains, and past human civilizations
Paleoanthropology
The evolutionary group that includes modern humans and our bipedal extinct relatives
Hominin
Learned behavior that is transmitted from person to person
Culture
The part of culture that is expressed as objects that humans use (stuff that people make)
Material Culture
Material objects made or modified for use by hominins
Artifact
Physical remains of part or all of once living organisms that have become mineralized by the replacement of organic with inorganic materials
Fossil
When and where the object is found
Context
The artifacts that are found at the location with context
Association
The study of the deposition of plant and animal remains and the environmental conditions affecting their preservation
Taphonomy
the analysis of the order and position of layers of archaeological remains; layers of deposits
Stratigraphy
Attempts to replicate ancient technologies and construction procedures to test hypotheses about past activities
Experimental archaeology
Similarities based on decent from a common ancestor
Homology
Adaptions to environments that yield similar traits shared between unrelated organisms
Analogy
A difference in a physical attribute between the males and females of a species
Sexual dimorphism
Species defined from fossil evidence, often covering a long time span
Paleospecies/Fossil Species
Walking on two feet
Bipedalism
Capable of walking or running on two legs, often only for a short time. Normally walks on four limbs
Facultative Bipedalism
Normally walks or runs on 2 legs. Is capable of different modes of locomotion, depending on environment
Habitual Bipedalism
Walking or running on 2 legs is the normal locomotion, no efficient alternatives
Obligate Bipedalism
Teeth that don’t sharpen each other when chewing; humans have this
Nonhoning chewing
The concept that evolutionary change takes place in some body parts or systems without simultaneous changes in other parts
Mosaic Evolution
In Tanzania, short strides, long arms, 3 million years ago, footprints
Laetoli
The evolutionary increase of the complexity and size of the brain
Encephalization
