Our paper is focused on two fundamental points: the first one is a terminological proposal and the second one is a question. Obviously these two things are strictly related one another. The terminological proposal is aimed to name “vertebral shock absorber” the human rachis (globally considered, when it is in physiological conditions) in its most typical function: to sustain static/dynamic stresses, that moreover are directed according to its axial direction, obviously when this coincides with gravitational line. This aspects can be studied by modal analysis and by the model of Eigenvectors and Eigenvalues. According to our opinion, the mechanical feature must be considered as prevalent if compared with the structural one. Following it human rachis is usually named “column”. This mechanic sustain is distributed on three lines that are summarily parallel and are linked one another (by isthmuses and vertebral arches to build an horizontal ring) so they can be considered a unique compact viscous-elastic system. Each one of these three vertical sub-structure is built as a stacking of metameric elements (modules) along a continuous line.

Man creates maps of land, of earth, of sky, of real or imaginary worlds, of micro-and macro-cosmos, of everything, including his own body.He uses many different matters to draw these maps.The first and meaningful one is the skin, so the map is on the body and the denomination "body map" means that the body itself is a map. When the map is separated from the body the most used support has been and is still now a writable surface, that is paper or a similar one. Since the late XX century, the digital tech-

Metaevolution is the evolution of the potentiality of evolution. This is somehow related to "Creativity" by Chaitin, "Self-production" or autopoiesis by Maturana &Varela, "Self-organization", to homeorhetic processes, to emergence passages and to the enlarging of the space of status of evolutionary changes. Metaevolutionary "jumps" in wetware are eukaryotic cell, aerobic metabolism, multi-cellular organization, NS. Metaevolution can be integrated with exaptation. Crossing over, alternative splicing, epigenetic modifications, transposons and retrotransposons represent the engine of the evolutionary process since they make possible the rearrangement of the metabolic processes and of the anatomo-physiological characteristics depending on the conditions of the external ambient. Metaevolution continues in cognitive-cultural sphere: cognitive transfert represents "noetic exaptation" and metaevolutionary jump. In both cases of Metabiology and of Metaevolution the prefix "Meta-" is useful to distinguish different epistemological levels, even if in a different meaning. A new horizon in Biology: no more dogmas, only the equation: "bio is evo & evo is bio" (see Dobzhansky), as it is meant also in Evo-Devo Biology.
