Unit 3: Human Society

1. Evolution of Man

The study of human evolution in human geography focuses on how early hominins adapted to varying geographic environments, leading to the biological and spatial development of Homo sapiens.

Key Stages of Hominin Evolution

• Australopithecus (approx. 4 - 2 million years ago): Emerged in Eastern and Southern Africa. They were bipedal but retained ape-like facial features and brain sizes.
• Homo habilis (approx. 2.4 - 1.4 million years ago): Known as the "handy man." First to extensively use stone tools. Found primarily in sub-Saharan Africa.
• Homo erectus (approx. 1.9 million - 110,000 years ago): First hominin to migrate out of Africa into Eurasia. Innovators of controlled fire and more complex Acheulean stone tools. Adapted to distinct climatic zones.
• Homo neanderthalensis (approx. 400,000 - 40,000 years ago): Adapted to the cold climates of Pleistocene Europe and Western Asia. Possessed a robust build and larger brain capacity; exhibited early cultural behaviors (burials, art).
• Homo sapiens (approx. 300,000 years ago to present): Modern humans. Originated in Africa.
  • "Out of Africa" Theory: Proposes that modern humans evolved in Africa and migrated outward around 60,000–70,000 years ago, replacing other hominin species (with some interbreeding, e.g., Neanderthals and Denisovans).

2. Race and Ethnic Group

Human geography distinguishes between the biological concept of race and the cultural concept of ethnicity, though both impact spatial distribution, social dynamics, and geopolitics.

Race

• Definition: Historically defined as a classification of humans based on inherited physical or biological characteristics (phenotypes like skin color, hair texture, bone structure).
• Geographical Perspective: Modern science rejects biological determinism; race is now widely recognized as a social construct.
• Griffith Taylor's Migration Zone Theory: An early 20th-century theory attempting to classify human races (Negrito, Negro, Australoid, Mediterranean, Nordic, Alpine, Mongolian) based on outward migration from Central Asia, driven by climate change. Though historically significant in geography, such classifications are now scientifically obsolete.

Ethnic Group

• Definition: A group of people who identify with each other based on shared cultural heritage, ancestry, history, homeland, language, or dialect.
• Ethnocentrism: The tendency to evaluate other cultures according to the preconceptions originating in the standards and customs of one's own culture.
• Spatial Dynamics: Ethnicity shapes cultural landscapes (ethnic enclaves in cities, e.g., "Chinatown" or "Little Italy") and can be a source of geopolitical conflict (e.g., ethnic cleansing in the Balkans or Rwanda).

3. Cultural Realms

A cultural realm is a large geographic region where traits such as religion, language, diet, customs, and economic development are generally similar.

Major Cultural Realms of the World

1. Occidental Realm: Includes Europe, North America, Australia, and New Zealand. Characterized by Indo-European languages, Christianity (historically), high urbanization, industrialization, and democratic institutions.
2. Islamic Realm: Stretches from North Africa through the Middle East to Central and Southeast Asia. Unified predominantly by the Islamic faith and, in the core region, the Arabic language.
3. Indic Realm: Covers the Indian subcontinent. Characterized by high population density, intense agriculture, and religious diversity (Hinduism, Islam, Buddhism, Sikhism).
4. East Asian Realm: Includes China, Japan, Korea. Influenced by Buddhism, Confucianism, and Taoism. High density, rapid modernization, and distinct linguistic families (Sino-Tibetan, Japonic).
5. Southeast Asian Realm: A transition zone marked by extreme fragmentation and diversity. Influenced by Indic, Islamic, and Chinese cultures.
6. Meso-African (Sub-Saharan) Realm: Characterized by vast tribal and linguistic diversity (e.g., Niger-Congo languages), animist traditions blending with Christianity and Islam, and a reliance on agrarian economies.

4. Religion

Religion is a core element of culture, significantly shaping the geographic landscape through architecture (temples, mosques, churches), sacred spaces, and pilgrimage routes.

Classification of Religions

• Universalizing Religions: Seek to appeal to all people worldwide. Actively proselytize.
  • Christianity: Largest globally; dominant in the Americas, Europe, and Sub-Saharan Africa.
  • Islam: Fastest-growing; dominant in the Middle East, North Africa, and parts of Asia.
  • Buddhism: Dominant in East and Southeast Asia.
• Ethnic Religions: Appeal primarily to one group of people living in one place. Do not actively seek converts.
  • Hinduism: Predominant in India and Nepal.
  • Judaism: Highly clustered in Israel and the United States (via diaspora).
  • Shintoism: Endemic to Japan.

5. Language

Language is the primary means of cultural transmission. The spatial distribution of languages reflects historical migrations, conquests, and trade.

Major Language Families

• Indo-European: Largest family (approx. 46% of the global population). Includes Germanic (English, German), Romance (Spanish, French), and Indo-Iranian (Hindi, Bengali, Persian) branches.

• Sino-Tibetan: Second largest. Mainly Mandarin Chinese, Burmese, and Tibetan.

• Niger-Congo: Covers most of Sub-Saharan Africa (e.g., Swahili, Zulu).

• Afro-Asiatic: North Africa and the Middle East (e.g., Arabic, Hebrew).

• Lingua Franca: A language mutually understood and commonly used in trade by people who have different native languages (e.g., English globally, Swahili in East Africa).

6. Indigenous People of the World

Indigenous peoples are the original inhabitants of a region, possessing distinct cultural, economic, and political systems.

Africa

• San (Bushmen): Hunter-gatherers of the Kalahari Desert (Southern Africa).
• Pygmies (e.g., Mbuti): Forest dwellers in the Congo Basin, known for their short stature and deep knowledge of rainforest ecology.
• Maasai: Semi-nomadic pastoralists in Kenya and Tanzania.
• Tuareg: Nomadic pastoralists of the Sahara Desert, often called the "blue people" for their indigo-dyed clothing.

Asia

• Ainu: Indigenous people of Hokkaido (Japan) and Sakhalin (Russia).
• Orang Asli: General term for indigenous groups of Peninsular Malaysia.
• Dayak: Riverine and hill-dwelling indigenous people of Borneo.

Australia

• Aboriginal Australians: The original inhabitants of the Australian mainland (e.g., Koori, Murri, Noongar). Characterized by ancient Dreamtime spirituality and deep connection to the land.
• Torres Strait Islanders: Indigenous to the Torres Strait Islands between Queensland and Papua New Guinea; distinct Melanesian cultural traits.

Eurasia (Europe and Northern Asia)

• Sami: Indigenous people of Sápmi (northern parts of Norway, Sweden, Finland, and Russia). Traditionally reindeer herders.
• Nenets & Chukchi: Indigenous Arctic peoples of northern Russia, practicing nomadic reindeer pastoralism.

America

• North America:
  • Inuit: Arctic regions of Canada, Alaska, and Greenland.
  • Navajo & Cherokee: Major Native American groups in the United States.
• Mesoamerica & South America:
  • Maya: Southern Mexico and Central America.
  • Quechua: Andean region (Peru, Bolivia, Ecuador); descendants of the Inca Empire.
  • Yanomami: Amazon rainforest (Brazil and Venezuela); one of the most relatively isolated indigenous groups.

7. Tribes of India

India has the second-largest tribal population in the world after Africa. Defined under Article 342 of the Indian Constitution as "Scheduled Tribes" (STs).

Geographical Distribution

1. North and North-Eastern Zone:
   • Himalayan belt (Jammu & Kashmir, Himachal Pradesh, Uttarakhand): Gaddis, Gujjars, Bhotias.
   • North-East (Assam, Meghalaya, Nagaland, etc.): Nagas, Mizos, Khasis, Garos, Bodos. Characterized by Tibeto-Burman languages and shifting cultivation (Jhum).
2. Central Zone:
   • Madhya Pradesh, Chhattisgarh, Jharkhand, Odisha, West Bengal. Houses the largest concentration of Indian tribes.
   • Gonds: One of the largest tribal groups, concentrated in the Deccan and Central India.
   • Santhals: Prominent in Jharkhand and West Bengal.
   • Bhils: Western and Central India (Rajasthan, Gujarat, MP), famous for their archery skills.
3. Southern Zone:
   • Karnataka, Tamil Nadu, Kerala, Andhra Pradesh.
   • Todas: Nilgiri Hills, pastoralists known for buffalo herding.
   • Chenchus: Andhra Pradesh/Telangana, traditional hunter-gatherers.
4. Island Region:
   • Andaman and Nicobar Islands.
   • Particularly Vulnerable Tribal Groups (PVTGs): Great Andamanese, Onge, Jarawa, Sentinelese (one of the world's last uncontacted peoples), and Shompens.

Characteristics of Indian Tribes

• Strong adherence to traditional animistic religions (though many have assimilated into Hinduism or Christianity).
• Economic models ranging from hunting-gathering (e.g., Sentinelese) to shifting agriculture (e.g., Baigas) to settled agriculture and industrial labor (e.g., Santhals, Gonds).
• Endogamous social structures with a strong sense of community and distinctive dialects (predominantly Dravidian and Austro-Asiatic families).
