Mid-Term Exam Flashcards
What are the 4 basic principles of Natural Selection?
1) Variation exists within populations
2) Variation can be inherited
3) Populations can have way more offspring than environment can handle
4) Competition for resources + heritable traits that affect individuals’ fitness variations in survival and reproductive rates
Subset of Physical Anthropology
The study of nonhuman primates, the closest living relatives of modern humans
Primatology
What are the characteristics of primates?
Opposable thumb Large brain Good stereoscopic vision (i.e. both eyes point in the same direction making 3D vision possible)Ability to brachiate (i.e. the ability to move arm over arm on a limb) Flexible elbows for hand rotation Grasping feet
What are the characteristics of apes?
Social mammals
Grasping hands
Bony, enclosed eye sockets
Relatively large brains OR intelligence
Manual dexterity OR skilled with hands OR opposable thumbs
Visual acuity OR excellent vision OR stereoscopic vision (3-dimensional vision)
Generalists – live in wide variety of environments
Locomotive flexibility OR collarbones at shoulders
Longer gestation (pregnancy) OR longer childhood
Study of the human past through material remains of human and hominin activity
Anthropology
A tested and repeatedly supported hypothesis
Scientific Theory
An object that has been manufactured or intentionally modified by a human or hominin
Artifact
Evidence of human activity that is non-portable (cannot be excavated and taken to a lab)
Feature
These make it clear that we share common ancestors
Homologous structures
How much of our DNA to we share with chimps?
98%
how well a species is able to reproduce in its environment
fitness
What are the Primate group types?
- multi-male
- single male
- Variable group formation w/habitat
What are the characteristics of a multi-male group?
Open, dangerous habitat
Several males needed to protect females
Competition between males, but cannot be too destructive
What are the characteristics of a single male group?
Resource poor habitat, but safer
Smaller groups of females
Males compete only for access to a female group
Males not in direct, daily competition
What are the characteristics of a variable group formation?
Move between habitats
Group structure changes with habitat
Difference between the average size of males and females
Sexual Size Dimorphism (SSD)
Artifacts that are found together and that presumably were used at the same time or for similar or related tasks
Assemblage
What do assemblages help to do?
help archaeologists make hypotheses about human behavior in a site or how artifacts were used
is the scientific and systematic study of human material remains
Archaeology
What are the four phases of archaeological research?
- Survey
- Excavation
- Laboratory Analysis
- Writing
What is the survey phase?
The physical examination of a space in which promising archaeological sites will most likely be found
What are the aspects involved in the survey phase?
GPR (Ground Penetrating Radar)
Magnetometry
Areal Photography
Lidar (Light raDAR) (by plane)
What is the excavation phase?
The systematic uncovering of cultural material
What are the aspects of the laboratory analysis phase?
Stratigraphy
Dendrochronology
Radio-carbon dating
