The Philosophy of Artificial Life. Ultimate Reality and Meaning 20 4: The theory of autopoiesis may also be used as a basis for a discussion of life concepts in high school, when issues such as the origins of life and cellular metabolism are dealt with. It is clear that the biochemical nature of living beings is quite particular to each species or individual.
Biologia Molecular, Citologia e Histologia. One biologiz lose from sight, however, that such a problem is also found in university biology textbooks. Los conceptos estruturales en el aprendizaje por investigacion. 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.
Life concept explicitly situated in a biological paradigm. Thus, when studying, we should be aware of the fact that the statements, generally speaking, refer to what is more frequent, to what happens in the majority of the cases or individuals.
Surely, it may exist, and maybe even necessarily exists, borderline instances between living beings and non-living matter. Textbooks that fundmentos living beings by means of a general description of taxonomic groups highlighting the attributes of each group.
What is the paradigm in which the textbook includes, implicitly or explicitly, the life definition if there is any? To cast them aside as exceptions seems to be, at first, quite a natural and easy solution. As a paradigmatic view of definitions releases us from the requirement of listing necessary and sufficient conditions for identifying in an essential and definitive way what are the phenomena that fall in a certain class, it makes it possible to clearly delimit, based on an precise theoretical justification, what are the phenomena in the domain of a given science.
The idea that a discussion of life concepts might contribute to biology teaching incited us to pursue new research questions: Help Center Find new research papers in: The demand for such an integrated approach can be thought of biolgia following from an understanding of the nature of msrtho, a fundamental feature in any discussion about biology teaching. As concerns the search for common patterns in the diversity of life, a reductionist tendency can be perceived, as the unity of life is emphasized in the molecular and cellular levels, with no corresponding effort to uncover features which might integrate our understanding of living beings in higher organizational levels.
Five books presented lists of properties to differentiate living from non-living beings. The Great Chain of Being. One book based its approach to the definition of life on the biological meaning of death, as the inevitable antithesis of life Figure 2.
It comes to mind the issue of how to study with the expected lucidity a set of phenomena and to build theories capable of explaining them in the absence of a more or less clear characterization of what are the very phenomena at stake.
The textbook sections about the origins of life contain important biologua concerning life concepts. A response to Gifford. We also found in licro analyzed textbooks an informational view of life. This argument is cundamentos 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 matter whether they are strictly dependent on cells or not.
The analysis of the textbooks was performed by applying a standard protocol, in order to guarantee a standardized appraisal of how the textbooks dealt with the problem of defining life and life concepts Figure rundamentos. Is there any concern about life concepts in biology teaching? What is the Books present a 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 same is not true of Paulinowho presents a coherent set of interrelated properties, based on a view of the scope of the Biological Sciences as well as of the way the living world is organized, from the simplest to the most complex levels of organization, suggesting the existence of some theoretical justification for their choice; nonetheless, the paradigm at stake is not explicitly stated. To put it differently, it is the case of trying to find a list of sufficient and necessary properties for a system to be characterized as living, with no theoretical paradigmatic justification for the choice of properties.
Textbooks that based its approach to the definition of life on the biological meaning of death. Click here to sign up.
Teoria Neodarwinismo by Dantefgle Fernandes on Prezi
The problem lies in the disproportionate emphasis on the micro-structure of biological systems, usually in an approach tending to isolate molecular and cellular structures from the organismic and environmental contexts. Their Structure and Representation. Remember me on this computer. At last, all living beings are subjected to death. The definition of life proposed includes a set of properties chosen under the light of an implicit theoretical paradigmatic justification, forming a coherent set of interrelated properties.
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 fundamsntos 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. Fundamentos de Biologia Moderna 2nd ed. All the instructions to fjndamentos functioning of the cell would be written, in code, in the DNA molecules.
We notice you are using an outdated version of Internet Explorer.
Rather, it is possible to explain the characteristic coexistence of that list of symptoms of life on the grounds of some set of causes. This distinction becomes difficult, however, when we consider equivocal cases such as viruses, viroids, prions, or a biochemical soup of RNA fragments in a laboratory. Another reductionist tendency is found in the way the phenomenon of life and the molecular or biochemical mwrtho are presented as closely related, while other views on life are relegated to a less important rank.
