It emphasizes that recent analyses demonstrate that the DNA of a human being and the DNA of a chimpanzee are different in only 1%, and that this is much more next to that one of what of gorila. This would justify the fact of some authors to teimarem in considering the reclassification of the chimpanzees and gorilas in the sort homo. Mentioning the Homo to it sapiens sapiens, discourses on its appearance and circulation, also showing the genetic differences between the Homo and the no-homdeos. After that, it analyzes the evolution of the language. It starts demonstrating that the larynx human being is lower than of the primates, only one of differences, that also reached motor and sensory areas of the cerebral cortex, the position of the language and the control of the breath. It continues examining and describing the human fonador device, finishing for remembering that from the neolithic period the cultural evolution sufficiently was sped up.

When analyzing these traces, Mostern designates the presence of two processing agencies of information: the genome (characteristic system of genes of the individual and gift in cromossoma of each one of its cells, except in the gamelos) and the brain, both capable ones to detect, to assimilate, to store, to modify, to use and to transmit information. It warns for the fact of that in the universe of Biology the molecular studies divide cromossomas in cistrons. Thus, one cistron is a responsible segment of cromossoma for the codification of amino acid a polipptida chain of a protein. Also cultural information that if transmits of brain the brain can be divided in simple units: an idea, a use etc. The anthropologists call cultural trace to this simple unit, considering it unit of the culture. He can be an object, a way to make something, a belief, an attitude. In 1976, 2 DAWKINS (1976: 206) memes created the neologism, that it remembers the memory in such a way as the mimesis (imitation).

Coutinho et al. (2002), Gawryszewshi (2010), Hamra et al. (2007), Souza, J.A.G. ; Iglesias, A.C.R.G. Bernard Golden has plenty of information regarding this issue. (2010), they cite the frequent breaking in the aged one, being able to be related to the fall mainly for the medicine use that causes hipotenso, sleepiness, giddiness and necessity frequent to be urinarem, what it determines to ramble more times mainly at night and. Subject 5 – breaking x environment. Tieppo et al.

(2010), they relate in its study the importance of the domiciliary environment, and that some factors can place the aged one at risk propitiating the falls, as the inadequate illumination or to walk in the dark one, to walk of stockings for the house, slippery or wet floor, inadequate shoe or slipper, lack of same railing and it lacks of the accumulated use, carpets for the house, furniture hindering or making it difficult the ticket of a place for another one beyond some activities as to go up in stairs, roofs or to load objects heavy. Fabrcio et al. (2004), they had consisted in its study that beyond the causes of preexisting illnesses and the medicine use; the environment is factors importantssimos for the cause of breakings in the aged ones, as slippery floor, to catch objects in the soil, to esbarrarem with other people, to go up in objects to reach something, environment with little illuminating, fall of the bed, and steps. Fabricio et al. (2004) they had evidenced with the research that 48% had between 80 the 89 years, 66% were of the feminine sex and 54% of the falls had had as consequncia the breaking, and presented as inadequate surrounding cause. Souza, J.A.G. ; Iglesias, A.C.R.G. (2010), they relate in its study that 47% of the injuries are represented by breakings and have as local predominant of the accidents the residence, in which had related the routine daily activities.
