Study Notes

HOMO HABILIS

Known as “Handy Man,” recognized as the first true human species.
Lived approximately 2.4 to 1.4 million years ago, primarily scavenging for food.
Earliest member of the Homo group, inhabiting Sub-Saharan Africa around 2 million years ago.
Mainly vegetarian, with a brain capacity of 610 cubic centimeters.
Brain structure indicates development of Broca’s area, associated with speech.
Characterized by a fuller, more rounded skull, slight forehead, and small face.

HOMO RUDOLFENSIS

Exhibited a longer face and larger molar and premolar teeth compared to Homo habilis.
Featured a larger braincase with expanded frontal lobes, reflecting advanced information processing.
Lived approximately 1.9 to 1.8 million years ago.

HOMO ERECTUS

Known as “Upright Man,” possessed body proportions similar to modern humans.
Existed from 1.89 to 143,000 years ago, adapted to hot climates and spread across Africa and Asia.
First known species to use fire, develop improvised tools (axes, knives), and engage in organized hunting.
Displayed significant physical changes with larger brains and bodies; primarily carnivorous diet.

HOMO HEIDELBERGENSIS

Characterized by a prominent brow ridge and stout body, lived around 700,000 to 200,000 years ago in Europe and Africa.
Notable as first early human species to inhabit colder climates, hunt large animals consistently with spears, and construct human shelters.

HOMO FLORESIENSIS

Nicknamed “Hobbit” due to its small stature of about 3 feet.
Existed from 95,000 to 17,000 years ago on Flores, Indonesia, cohabiting with other dwarf species.

HOMO SAPIENS

Meaning “Wise Man,” appeared about 200,000 years ago and is the only extant species of the Homo genus.
Significant development in culture and society noted in relation to survival strategies and adaptation.

HUMAN ORIGIN

Human evolution involves dynamic changes enabling adaptation to various environments, leading to societal and cultural development.
Interest in understanding human origin centers on analyzing adaptive capacities to cope with environmental challenges.

BIOLOGICAL EVOLUTION

Refers to genetic changes in populations across generations, influencing physical traits, organ size, and locomotion.
Includes the evolution of straight posture and adaptation to bipedalism.

Cultural Evolution

Also known as socio-cultural evolution, representing the development from simpler to more complex cultures.
Charles Darwin proposed natural selection as a mechanism for evolution—advocating survival of the fittest.
Emphasizes the elimination of less adaptive species over time.

HOMO NID HIERARCHY

Includes significant early human varieties such as Ardipithecus (Kadabba, Ramidus) and Australopithecus (Gracile: Anamensis, Afarensis, Africanus; Robust: Aethiopicus, Robustus, Boisei).

HOMO SAPIENS NEANDERTHALENSIS

Known as Neanderthal Man, adapted to cold climates, lived 200,000 to 28,000 years ago.
The first to engage in burial practices and use animal skins for clothing.

HOMO SAPIENS SAPIENS

Referred to as Cro-Magnon, emerged 40,000 to 10,000 years ago during the last Ice Age.
Marked by anatomical modernity, production of art, cave paintings, and decorated tools and accessories.

CHARACTERISTICS OF HUMAN SOCIETY

Comprises a social system, is relatively large, and recruits most members internally.
Sustainable across generations with shared culture and designated territory.

Types of Society

Hunting and Food Gathering Societies: Earliest form, relying on foraging and hunting for survival using simple tools.
Horticultural Societies: Emerged with the adoption of farming techniques, employing human energy and handheld tools for cultivation.
