Knowra Cognitive revolution Cognitive revolution The cognitive revolution is the proposed relatively rapid emergence of complex symbolic behavior and modern cognition in human prehistory, especially among Homo sapiens.
Blombos Cave : A South African archaeological site with Middle Stone Age evidence of engraved ochre, shell beads, and toolmaking. Its engraved ochre and beads are often cited as evidence of symbolic behavior before the proposed revolution.
Gradualism : The view that evolutionary or historical change occurs through slow, cumulative transitions. It contrasts with accounts that attribute modern cognition to a rapid prehistoric shift.
Language evolution : The biological and cultural processes through which human language arose and changed. Language is often proposed as a capacity that enabled complex symbols and cumulative culture.
Upper Paleolithic : The later part of the Paleolithic, marked in many regions by diverse tools, art, and other cultural changes. European accounts historically associated the cognitive shift with this archaeological period.
Symbolic thought : The capacity to use signs, objects, or actions to represent meanings beyond their immediate physical properties. It is a defining behavior commonly used to identify the proposed cognitive transition.
Sulawesi cave art : A record of figurative and hand-stencil cave paintings on the Indonesian island of Sulawesi, including works tens of thousands of years old. Its early figurative art challenges accounts placing symbolic expression’s emergence only in Europe.
Multiregional evolution : A model proposing that modern humans evolved across several regions from interconnected archaic populations. It offers a different framework for human origins than a single African emergence followed by dispersal.
Cumulative culture : The gradual accumulation of knowledge and practices across generations, with later innovations building on earlier ones. It can produce complex technologies without requiring a single abrupt cognitive mutation.
Middle Stone Age : An African prehistoric period characterized by diverse stone technologies and evidence of changing human behavior. African finds from this period place symbolic practices earlier than classic European timelines.
Cave painting : Images made on cave walls or ceilings, often depicting animals, humans, or abstract signs. Cave paintings provide visible evidence of representation and shared cultural conventions.
