| Summary: | According to the informatics-cybernetic model of the Humankind’s hierarchical system, information technologies (IT) appear historically: 1) signal positions/sounds/movements: the characteristic size (radius of the same area circle) is ~64 m, the anthropogenic impact accuracy is ~28 cm, start ~ 28.23, culmination ~9.26 million years ago, carrier of pre-humans Hominoidea; 2) mimics/gestures: ~1 km and ~1.8 cm, ~1.86 and ~0.612 million years ago, Homo archaeo-paleolithicus and Homo mezo-paleolithicus; 3) speech/language: ~15 km, production technology accuracy ~1.8 mm, ~123 and ~40 thousand years ago (near the IT-initiated Upper Paleolithic revolution), Homo sapiens' (H.s. paleolithicus superior and H.s. neolithicus); 4) writing: ~222 km and 80 μm, ~6100 and ~700 years BC (near the Urban revolution of "Axial" time), Homo sapiens'' (H. paleometallicus and H.s. neometallicus); 5) replicating texts: ~3370 km and 5 μm, ~1446 and ~1806 years AD (near the industrial revolution), Homo sapiens'''; 6) Computer: ~51 thousand km (planetary) and 0.35 μm, ~1946 and ~1970 (near the computer revolution – the creation of microprocessors), Homo sapiens ''''; 7) Network: ~773 thousand km (Near Cosmos) and 23 nm, ~1979 and ~2003 (about the revolution of mobile telephony, Internet, etc.), Homo sapiens'''''; 8) Nano-IT (possibly, nano-hardware supported selective telepathy): ~11.7 million km (Intermediate Cosmos) and 1.5 nm, ~1981 and ~2341, Homo sapiens'''''' (according to the extrapolation of the archaeological epoch "Fibonacci’s" model H.s. informaticus). This list reflects the genesis of IT – part of the genesis of hierarchies (subsystems) in the Humankind’s system. The main components of the genesis of hierarchies include anthropo-, psycho-, techno-, cultural-, socio-, ideal-genesis etc. Thus, the genesis of IT, which has quantitative (model) estimates of the characteristic times of its course, can act as a marker both for the genesis of hierarchies in general and for its components.
