Anthropology Chapter 1: Introduction

Chapter 1: Introduction to Anthropology

Anthropology is the study of humans, past and present.
Culture is a shared set of beliefs, values, and practices that give meaning to human life.
Participant observation involves immersing oneself in a culture to collect data through firsthand experience.
The four subfields of anthropology are:
- Biological Anthropology: Focuses on the biological and evolutionary aspects of humans.
- Archaeology: Studies past human cultures through material remains.
- Linguistic Anthropology: Examines the structure, function, and evolution of human language.
- Cultural Anthropology: Focuses on the diversity and variation of human cultures.
The holistic approach, also known as holism, is a core principle in anthropology that emphasizes the interconnectedness of all aspects of human existence.
Anthropologists use several research methods, including:
- Participant observation
- Interviews
- Surveys
- Archival research
- Ethnographic fieldwork
Salvage ethnography was a practice in the early 20th century to collect cultural information from cultures considered to be "disappearing."
Unilinear theory of cultural evolution: A now-debunked theory that argued that cultures progress through a series of stages.
Eurocentric bias and colonialism influenced early anthropological practices, often at the expense of indigenous populations.
Modern anthropologists use a more critical and self-reflective approach, acknowledging the complexities of cultural change and the need for respect and collaboration in research.
Anthropology is increasingly relevant to the business world, popular culture, and the challenges of globalization.
Contemporary anthropology explores themes related to:
- Environmental change
- Globalization
- Technology
- Health and well-being
- Climate change

Chapter 2: The Primates

Taxonomic order refers to the hierarchical classification of organisms from broad to specific.
Primates, an order of mammals, share common characteristics, including:
- Prehensility: The ability to grasp objects using five-fingered hands.
- Brachiation: The ability to swing from trees using their arms.
- Omnivorous: Ingesting a diet of both plant and animal matter.
- Dental formula: A specific arrangement of teeth.
Hominins are a group of primates that are closely related to modern humans.
Affiliative behavior is a key aspect of primate social life, which includes grooming, play, and other behaviours that strengthen bonds.
Egalitarian societies are where power and resources are distributed evenly among members.
Bushmeat refers to wild animals hunted and consumed, and can be a crucial part of diets in many Indigenous populations.
The Anthropocene is a proposed geological epoch characterized by human activities having a dominant impact on the Earth's systems.

Chapter 3: Human Evolution

A hypothesis is a testable proposition that explains a phenomenon.
A theory is a well-substantiated explanation of a phenomenon supported by extensive evidence.
Inheritance of acquired characteristics is a discredited idea that traits developed during an organism's lifetime could be passed down to offspring.
Genetic drift is a random process where genetic traits become prevalent in a population due to chance events.
Natural selection is a process that favors traits and behaviors that increase survival and reproduction.
Mutation is a permanent change in the DNA sequence.
Gene flow is the transfer of genetic material between populations.
Adaptive radiation is a rapid diversification of species from a common ancestor to fill various ecological niches.
Speciation is the process by which new species arise from existing ones.

Chapter 4: The Early Hominins

Paleoanthropology is the study of human origins and evolution using fossil evidence.
The fossil record provides a tangible history of life on Earth.
Taphonomy is the study of the processes that occur to an organism after death, influencing its preservation as a fossil.
Hominins include all species in the human lineage, characterized by traits like bipedalism (walking upright on two legs).
Bipedalism, a key hallmark of hominin evolution, offers advantages like energy efficiency, carrying objects, and seeing over tall grasses in open landscapes.
The savannah hypothesis suggests that bipedalism evolved in response to changes in the African environment, favoring organisms that could see over tall grasses, leading to a shift to more open environments.
Potassium argon dating is used to determine the age of ancient volcanic rocks.
Radiocarbon dating is used to date organic materials.
Dating by association determines an object's age based on its context alongside other objects of known age.
The foramen magnum is the opening in the skull where the spinal cord connects to the brain. In humans, it sits more centrally beneath the skull, indicating adaptation for bipedalism.
Australopithecus afarensis is an early hominin famous for the "Lucy" skeleton.
Homo naledi is a recent discovery, with a mix of primitive and more advanced features.
Homo erectus were the first hominins to migrate out of Africa.
Homo neanderthalensis, commonly known as Neanderthals, were a close relative of modern humans.

Chapter 5: The Upper Paleolithic

The archaeological record consists of material remains left by past societies.
A habitation site is a place where people lived, and the remains of activities, tools, and structures can provide insights into their lives.
The Lower Paleolithic, also called "Old Stone Age," began around 2.6 million years ago.
Coprolites are fossilized feces that can provide information about diet and health.
The atlatl is a spear thrower that allowed for greater accuracy and velocity in hunting.
