From the 8 books analyzed, 5 moddrna a definition of life. It conflates the molecular and cellular mechanisms involved in the pathological process with the pathological phenomenon itself. The gene that codifies the prion protein is in the host itself, so that the prion lacks genetic material and, in fact, cannot do copies of itself in the same sense as typical living beings do. Although most books do not include a chapter or section on the concept of life, it is possible to draw some general ideas about this issue from the texts, through an analysis of how the authors think of biology, the making of science, the scope of the field, the organization of the contents, etc.

The definition of life proposed is limited to a list of properties, seeking to characterize what a living being essentially is and what a non-living being essentially is essentialist view.

livgo Among several misunderstandings amais difficulties resulting from this metaphor, we have the problem that it emphasizes a purely informational conception of life.

Life concept explicitly situated in a biological paradigm. Viruses and other molecular structures showing distinctive properties of both inanimate matter and living beings seem to be exceptional because they contradict our intuitions about the distinction between these two classes of entities. Their Structure and Representation. From a definition of death as the irreversible process of losing the highly organized activity that characterizes life, they discuss the definition of life itself.

We also found in the analyzed textbooks an informational view of life. Autopoietic systems, replicators, and the search for a meaningful biologic definition of life. Nevertheless, when assuming such an approach, we should not underestimate the risks of losing from sight the need for an understanding not only of the molecular and cellular components of living systems, but also of the organizational principles by means of which the very systems which we classify as living can emerge from those components.

The definition of life proposed includes a set of properties chosen under the light of an implicit theoretical paradigmatic justification, fundamntos a coherent set of interrelated properties.

At last, all living beings are subjected to death. Here, it is worth observing that Soares The textbook sections about the origins of life contain important issues concerning life concepts. One cannot lose from sight, however, that such a problem is also found in university biology textbooks. Emmeche observes that definitions of life are seldom discussed in depth or even mentioned in biology textbooks and dictionaries. Life would ra when an aggregate of molecules, endowed with the ability to perform ordered chemical reactions, amwbis from the environment raw materials and energy, managed to maintain its organization and isolate itself from the environment.

This argument is not sufficient, however, for avoiding a violation of the Cell Theory by viruses, as this theory states that the cell is the basic structural unit of all living beings, and this does not hold in the case of viruses, no modeerna whether they are strictly dependent on cells or not.


What is the paradigm in which the textbook includes, implicitly or explicitly, the life definition if there is any? We emphasized how the search for moderan features in biological processes and common patterns in the diversity of living beings, which is an inevitable part of any attempt to define life, makes a more integrated approach to biological knowledge possible.

We decided then to make an analysis of Brazilian high-school biology textbooks, as textbooks represent, in Brazil, the major way of transposing contents from scientific to school knowledge Razera et al.

We have already analyzed 8 modernaa a total sample of 20 books. What is the definition of life presented by the textbook, if there is ambis An emphasis on the description of morphological and anatomical features characterizing groups of plants and animals reinforced the search for lists of essential properties.


Emmechefor instance, does not consider viruses as borderline cases, but as pathological forms of life, a kind of ultimate parasites, as they presuppose in the functional and evolutionary sense the existence of living cells. The treatment of this problem revolves around the possibilities of an origin by divine creation, or chemical evolution, or in some extraterrestrial place.

We amsbis think of life as both form and matter — something with both informational-organizational and material-physical aspects —, but this understanding of life puts too much emphasis on the informational aspect cf.

Fundamentos de Biologia Moderna 2nd ed. What is the Books present a definition of life? It is important to stress, however, that the claim that the Earth is living strains the ordinary concept of life Bedauand demands a justification through a proper conceptual analysis.
