Document Summary
Wednesday, september 21st & friday, september 23rd, 2016. Collection of cells specialized for processing info. Information: matter organized into signal stream (i. e. , msg) having capacity to reduce uncertainty in state of affairs. Mathematical meaning: signal altering probability of system state. Transduction/detection: converting stimulus events into neural events. Coding: evaluating, categorizing, organizing, assembling, & preparing info for further coding, transmission and/or storage. Communicating: transferring info from 1 place in space/time to another. Information processing within cells led to correlated action & specialization of cellular organelles increases functional cellular complexity. Information processing b/w or among cells led to integrative action & specialization of cell groups increased complexity multicellular organisms. Information processing b/w multicellular organisms made possible society, culture, civilization. Evidence that abstract thought emerged ~ 40 000 yrs ago: the lion-man : found in germany"s hohlenstein-stadel cave, oldest known anthropomorphic animal figurine, suggests: artist conceived of imaginary figure. Reconstruction based on nandy 1st neanderthal skull found in shanidar caves of.
