Brain/Mayr: the human brain acquired its still existing skills about 100,000 years ago.
All the achievements we are looking back at today were made with a brain that was not developed for them by the selection!
Three brain regions: 1) For reflexes ("closed programs"). 2) Information intake ("open programs"), languages, norms, behavior. What was once learned is difficult to forget. "Simple coinage": 3) Regions not yet defined, "memory", "storage".
Brain/Evolution/Mayr: Australopithecus: 400 500 cm³ ((like a anthroid ape) Homo erectus 750 1250 significantly larger brains only in the last 150,000 years.
Language/Animals/Mayr: There is no language among animals. Their communication systems consist in the exchange of signals. There are no syntax and grammar.
Language/brain: could the absence of language be a reason why the Neandertals did not exploit their brain better?
Language: evolved from about 300,000 200,000 years ago in small groups of hunters and collectors due to a selection advantage. Good location for brain enlargement.
Brain: a factor that led to a halt in brain development was perhaps the enlargement of the group.
In larger groups, the reproductive superiority of a better-equipped leader is lower, while those with smaller brains enjoy better protection, longer life and greater reproductive success.
Stagnation: social integration of people contributed enormously to the evolution of culture, but may have initiated a period of stagnation in the evolution of the genome.
Mind: conceptual confusion: false limitation to the mental activities of humans.
Animal/Mind: it has been shown that there is no categorial difference between the mental activities of certain animals (elephants, dogs, whales, primates, parrots) and those of humans.
Consciousness/Animal: the same applies to the consciousness, a basic version of which is even to be found in invertebrates and possibly protozoa.
Mind/Mayr: there was simply no sudden emergence of the mind._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number. The corresponding books are indicated on the right hand side. ((s)…): Comment by the sender of the contribution.
