Homo Species Overview

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.
