Study Notes

Macroevolution and Formation of New Species

Macroevolution focuses on the formation of new species and relationships between species groups
A species is a population that interbreeds to produce viable, fertile offspring
Speciation occurs slowly due to adaptive change, as proposed by Darwin in his "Origin of Species"
Rapid speciation can occur with genetic mutations in key regulatory genes, which result in new body plans
Homeobox genes are responsible for large-scale effects on an organism's growth and development
Natural selection favors organisms maintaining mutated forms through adaptation to their environment
Continental drift impacts the evolution of species, distributing fossil primate groups and causing climate change

Evolution of Primates

The first primate-like mammals appeared approximately 65 million years ago
Diurnal anthropoid primates emerged approximately 40 million years ago
Hominoids started appearing in Asia, Africa, and Europe approximately 23 million years ago, at the beginning of the Miocene Period

Hominoids

Hominoids are tailless primates with broad shoulders, including all living and extinct apes and humans

Miocene Period

This period is considered the golden age of hominoids, where African and Eurasian landmasses were connected
Miocene fossil remains of apes have been found in China, France, and Eastern Africa

Early Humans

Humans are distinct from other hominoids due to their bipedalism, which is walking on two feet
Humans have striking differences from their closest primate relatives, namely: larger brains and bipedal locomotion

Australopithecus

Australopithecus is believed to be the earliest ancestor of humans
Despite their bipedalism, Australopithecus had a small brain size in proportion to their body size

Homo Habilis

This species is believed to have evolved from one of the Australopithecus species
Homo Habilis had relatively smaller teeth and larger brains than Australopithecus

Homo Erectus

Followed Homo Habilis in the human evolutionary line
They had even larger brains and were able to adapt and survive effectively

Paleolithic Period (Old Stone Age)

Divided into: Lower Paleolithic Period, Middle Paleolithic Period, and Upper Paleolithic Period

Lower Paleolithic Period

This period is marked by the existence of Homo Erectus
Hand axes and other tools were created, demonstrating the homo erectus's ability to create specialized tools for particular tasks

Middle Paleolithic Period

Homo sapiens emerged during this period
More efficient tools were created for prying, lifting, holding, and pulling

Upper Paleolithic Period

Homo sapiens continued to thrive in this period
Blades were the most distinctive tool developed, indicating increased specialization in tool creation

Cultural and Sociopolitical Evolution

The cultural and sociopolitical dimensions of humankind have undergone massive changes over millennia
Key periods include the: Neolithic Revolution, Development of States, Contemporary Times, and the Practice of Democracy

Neolithic Revolution

It's also known as the "New Stone Age Revolution" due to the use of polished stone tools and techniques
Marked a time of fundamental change as food production became central - a shift from hunting and gathering to the raising of crops and animals
Settlements in villages developed to grow crops and raise animals
Agricultural efficiency led to greater leisure time, which fuelled progress in arts, science, and technology, such as tool development, temple construction, and irrigation
Increased populations led to the formation of communities and eventually cities
The revolution significantly altered the ecosystem:
- Irrigation often destroyed fertile areas
- Excessive soil erosion made waterways less navigable
- Competition for fertile land led to wars and hunger
Demand for tools and raw materials increased significantly, leading to the rise of trade and economic networks

Early Civilization and the Rise of the State

The word "civilization" is derived from the Latin term "civis," meaning "a person who lives in the city," and "civitas," meaning "urban community"
Anthropologists define “civilization” as societies composed of large populations living in cities
City dwellers are socially stratified, ruled by an elite governing through centralized political systems called states
Early civilizations emerged around 6,000 years ago in different locations:
- Mesopotamia
- Egypt's Nile Valley
- Indus Valley
- China
- Peru
- Mesoamerica

What Characterized Early Cities?

Large size in terms of land area and population
Organized planning by a central authority, technological intensification, and social stratification

Catalhoyuk

This is an example of an early, compact settlement in Turkey, dating back 9500 years
Archaeological evidence suggests organized planning in early urban centers

Indus River Valley

Flood control and protection were critical components of the ancient cities in this region

Mohenjodaro

This urban center, originating approximately 4500 years ago, housed a population of 20,000
The city was built on an artificial mound to safeguard against floodwaters

Mesoamerican City Teotihuacan

Founded 2200 years ago, Teotihuacan incorporated spiritual beliefs and social order into its architecture
The city's layout reflected the solar calendar, creating a unified spatial pattern, such as the Street of the Dead
Teotihuacan was suddenly abandoned in the 7th century, possibly due to environmental factors
The Street of the Dead was a central path, connecting important monuments

Early Civilizations and the Significance of Cities

Large-scale, organized cities represent a significant development in human culture
They weren't merely expanded villages but rather exhibited a major transition in human society

Evidence of social stratification in early societies is found in:
- Laws and written documents
- Archaeological features such as dwelling size and location
- Mortuary evidence, including burial customs and grave goods

Central Government

Early civilizations had an emerging governing elite to address the complexities of urban life
Central governments provided a system for managing urban life, including the development of army and fortifications, taxation, legal justice, and ensuring safety of life and property
Sources of evidence for centralized authority include:
- Law codes
- Temple records
- Royal chronicles
Written forms or recorded information, such as documents and artifacts, also indicate the presence of centralized authority

Earliest Forms of Governments

Early city governments were typically headed by a king and his advisors
Hammurabi, the Babylonian king who lived in Mesopotamia (3700-3950 years ago), is known for issuing the Code of Hammurabi, which is a set of laws

The Code of Hammurabi

The Code is believed to have established the principle of "innocent-until-proven-guilty."
It prescribed legal procedure and penalties for perjury and making false accusations

Inca Empire

The Inca civilization of Peru was one of the most advanced in the Americas and even surpassed several civilizations in Eurasia
The emperor was considered a divine son of the Sun God and held supreme authority over the government
Inca governance involved a highly efficient bureaucratic system that effectively managed all levels of government affairs.
