Buried Cities and Lost Tribes: Comprehensive Archaeology Notes

Introduction to Archaeology

• Archaeology is the study of the human past through material culture. Its source of information is the archaeological record.

• Paleontology is the study of past life, using the fossil record. Its domain overlaps with archaeology but focuses on non-human life and fossils.

• Archaeologists do not study dinosaurs; paleontologists do.

• The domains overlap only partially; archaeology begins with material culture around ~$3.3\ \mathrm{mya}$ (million years ago) with the oldest stone tools.

• The history/humanities distinction:

  • History is the study of the past using written records.

  • The domain of history begins around ~$5.4\ \mathrm{kya}$ (thousand years ago).

  • Archaeology and history can complement each other and fill gaps in each other’s records (e.g., minorities often underrepresented in early writings).

• Prehistory vs History:

  • Prehistory = period of human history before the advent of writing.

  • History = period after the advent of writing.

• Goals of archaeology combine history and science.

• Key takeaway: archaeology extends our understanding into deep time beyond written records and helps reconstruct human life through material remains.

Paleontology vs Archaeology

• Paleontology studies past life; its main data source is fossils.

• Archaeology studies humans and their past through material culture and the archaeological record.

• Domain distinction: archaeology focuses on human activities, tools, sites, and cultural remains; paleontology focuses on non-human life forms preserved as fossils.

• Overlap: both study the past, but the primary evidence and questions differ.

• Example distinction: if you find ancient footprints with stone tools, both fields may contribute, but the interpretation depends on whether you’re focusing on human behavior (archaeology) or paleo-biology (paleontology).

Domain, Timeline, and the Record

• The earliest hominin ancestor is dated to about $7\ \mathrm{mya}$.

• The earliest stone tools appear at about $3.3\ \mathrm{mya}$, marking the beginning of the archaeological record.

• You are here: Present.

• Exclusive domain of paleontology: non-human life/biological fossils; archaeology’s domain starts with material culture.

• Archaeology + paleontology: overlapping but distinct domains, with archaeology anchored in the archaeological record (material remains) and paleontology anchored in fossils.

Earliest Stone Tools and Early Humans

• Earliest stone tools: approximately $3.3\ \mathrm{mya}$, found in Kenya, Africa.

• These tools mark the beginnings of material culture that archaeologists study.

• The timeline often expressed as: earliest hominin ancestor = $7\ \mathrm{mya}$; earliest tools = $3.3\ \mathrm{mya}$; present = today.

How long is the archaeological record?

• Question presented: How long is the archaeological record?

  • A) About $3.3\ \mathrm{million\ years}$

  • B) About $4.54\times 10^{9}$ years

  • C) About $5.4\ \mathrm{kya}$

  • D) About $250\ \mathrm{years}$

• Correct answer (from the context): About $3.3\ \mathrm{million\ years}$ (the appearance of the earliest stone tools).

Key concepts: Time scales and definitions

• Domain of history begins at $5.4\ \mathrm{kya}$ (the rise of writing).

• Prehistory = before writing; History = after writing.

• Archaeology can address biases in historical records by:

  • Providing material evidence for events, populations, and practices not captured in written sources.

  • Revealing cultural aspects of minorities and overlooked groups.

How archaeology complements historians

• Archaeology can reduce biases in the historical record, which often does not adequately represent minorities.

• By integrating material evidence with written sources, historians gain a more complete picture of the past.

The Deep Antiquity of Humankind and the Usher Debate

• In earlier centuries, the Earth and humanity were thought to be young (Young Earth theory).

• James Usher (1581–1656) proposed a Young Earth chronology (Creation took place on Saturday evening, October 23, 4004 BCE).

• In the 16th–17th centuries, Europeans widely believed in a Young Earth.

• The shift to an old Earth came with geological and archaeological reasoning:

  • Catastrophism vs Uniformitarianism.

  • Catastrophism (Creation 1–4): Time framed by catastrophic events.

  • Uniformitarianism (18th century): The idea that the laws of nature are constant across time and space (the Grand Canyon as an example).

• The old-Earth hypothesis arises from applying rates of ongoing processes over long times to explain geological features.

• Key implication: Earth and human history are far longer than a few thousand years, enabling a deep past for archaeology to explore.

Uniformitarianism and the Old Earth Hypothesis

• Uniformitarianism asserts that rates of natural processes are constant over time, enabling long timescales to produce large geological features.

• Example: Grand Canyon can be explained by erosion over long times with constant physical laws.

• Mathematical relation (conceptual):

  • Rate of process × Time = Results

  • Time = \frac{Results}{Rate\ of\ process}

• This framework supports the view that the Earth is old enough to harbor deep time for human evolution and cultural development.

Jacques Boucher de Crèvecoeur de Perthes and Early Archaeology

• Jacques Boucher de Perthes (1788–1868) conducted important work on the Somme River gravel, France.

• He documented artifacts in layers that helped establish the idea that humans existed alongside extinct animals in the past.

• This contributed to recognizing deeply antiquated human past and supported the shift toward modern archaeology.

• The statement on inscriptions: Until stone tools were found in the same layer as bones of extinct animals, the deep antiquity of humankind was not widely accepted.

The Establishment of Deep Antiquity

• The recognition that the Earth is old and that humans have a deep past paved the way for archaeology as a discipline.

• Two foundational claims:
  1) The Earth is old.
  2) Humans have a deep past, too.

• With these assumptions, archaeology gains coherence as the study of the past through material remains.

Goals of Archaeology (Overview)

1) Reconstruct the history of human populations (What? When? Where?)
2) Explain this history (Why?)

Reconstructing History (What, When, Where)

• What happened on a site?

• What were people doing?

• What tools were used?

• When did they arrive and leave the site?

• Where did they come from and go to?

• The emphasis is on assembling a historical narrative from physical evidence.

Explaining History (Why)

• Address big questions about human dispersal and social change:

  • Why did people disperse around the globe so rapidly?

  • Why is there a sexual division of labor?

  • Why domesticate plants and animals?

  • Why start living in villages, then in cities?

  • Why monumental architecture in state societies?

• This involves theoretical interpretation of the material record and integration with broader theory.

The Relationship: Archaeology as History and Science

• Archaeology is both history and science: it documents particular events and also studies regularities across classes of events.

• Example: A class of events = political revolutions.

• By studying multiple revolutions, archaeology (and associated social sciences) can infer patterns about political change, not just a single event.

The 24-Hour Clock of Earth's History (Illustrative Timeline)

• A visual, illustrative mapping of major events onto a 24-hour clock:

  • 0:00 Formation of Earth

  • 0:00–3:00 AM Meteorite bombardment

  • 4:00 Origin of life

  • 5:36 Oldest fossils

  • 9:04–9:52 Trilobites and other early life forms (illustrative markers)

  • 10:24–11:39 Various life forms like jellyfish, seaweeds, etc. (illustrative markers)

  • 12:00 Noon Abundant banded iron formations

  • 2:08 PM Single-Celled Algae (Acritarchs)

  • 3:00 PM–present: Humans and mammals appear much later in the clock (notated as present).

• Purpose: to convey the long timeline of life on Earth and place human history within deep time.

Summary: The Rationale for Modern Archaeology

• The establishment of deep antiquity for humankind made archaeology sensible as a discipline.

• The idea that humans have a deep past justifies studying material remains to understand long-term human development.

• The discipline sits at the intersection of history (narratives of past events) and science (generalizable patterns across societies and time).

Key Takeaways to Memorize

• Archaeology begins with material culture ~$3.3\ \mathrm{mya}$; paleontology focuses on fossils, not stone tools.

• History begins with written records ~$5.4\ \mathrm{kya}$; archaeology helps fill gaps in the written record.

• Prehistory vs History: before vs after writing.

• The deep antiquity of humankind supported the view that archaeology is a legitimate, wide-ranging field that investigates long timescales.

• Uniformitarianism supports an Old Earth view and provides the methodological basis for long timescales in archaeology and geology.

• The goals of archaeology are reconstructing past human populations and explaining why those patterns occurred.

• Archaeology can reveal biases in historical records and help relate human questions to material evidence.

Important Definitions and Formulas

• $\text{mya} = \text{million years ago};\quad \text{kya} = \text{thousand years ago}$

• Time estimation formula (conceptual):
  $\text{Time} = \frac{\text{Results}}{\text{Rate\ of\ process}}$

• Example relationship: ${\text{Rate of erosion}} \times {\text{Time}} = {\text{Grand Canyon}}$

Additional Contextual Notes

• The slides emphasize that archaeology and history are complementary, not mutually exclusive.

• The earliest dated human tool use (~$3.3\ \mathrm{mya}$) marks a pivot where cultural behavior leaves material traces that archaeology can study.

• The Usher debate represents a historical context for how scientific thinking about time evolved from a young-Earth paradigm to an old-Earth paradigm.

• Perthes’ work reinforced the idea that humans coexisted with extinct animals in geological strata, strengthening the deep antiquity concept.
