\u00bfES CORRECTA LA IDEA DE PASTEUR DE LA AS\u00cd LLAMADA \u00abLEY DE LA BIOG\u00c9NESIS\u00bb QUE REZA QUE \u00abTODA VIDA SALE DE VIDA\u00bb, A LA QUE SE AGARRAN LOS CREACIONISTAS?: NO<\/u><\/strong><\/p>\n\n\n\n

\u00abEsta idea, muy popular durante un tiempo, surge como conclusi\u00f3n final de la demostraci\u00f3n de que no exist\u00eda la generaci\u00f3n espont\u00e1nea<\/em> en la que se cre\u00eda desde que Arist\u00f3teles la hab\u00eda formulado (\u00a1el viejo Arist\u00f3teles!, \u00a1tan falto el pobre de medios –de microscopios en este caso– y sin embargo tan sobrado de ideas interesantes pero no contrastadas!). Pasteur demostr\u00f3 mediante el microscopio que exist\u00edan peque\u00f1as vidas, \u00abmicro-bios\u00bb<\/em>, peque\u00f1os seres vivos que eran los que se encargaban de generar la descomposici\u00f3n de los cad\u00e1veres, y otras muchas cosas que se sospechaban pero que no hab\u00edan podido demostrarse hasta que no pudimos alcanzar, gracias a la ciencia, esa fase tecnol\u00f3gica. <\/p>\n\n\n\n

Dicho esto, no es menos cierto que esa frase de cabecera,\u00a0\u00abtoda vida sale de vida\u00bb<\/em>, no deber\u00eda haber sido as\u00ed formulada por la imaginer\u00eda popular –Pasteur y sus colegas sab\u00edan de sobra que a lo que quer\u00edan referirse no era exactamente lo que esa inadecuadamente c\u00e9lebre frase dec\u00eda como supuesto resumen–, pero entonces, en aquella \u00e9poca, se pensaba en la semblanza general que efectivamente la vida proven\u00eda siempre de la vida y por eso nadie puso reparos a lo evidentemente inadecuado de su contenido. <\/p>\n\n\n\n

Tiempo m\u00e1s tarde, cuando la ciencia continuando en la colaboraci\u00f3n del desarrollo de la tecnolog\u00eda se dispuso a s\u00ed misma de mejores medios a\u00fan para estudiar la materia, se estableci\u00f3 que la unidad de la vida era la c\u00e9lula (de c\u00e9ldula*>c\u00e9llula*>c\u00e9lula, \u00abpeque\u00f1a celda\u00bb, en lat\u00edn). Eso quiere decir que seg\u00fan los requerimientos cient\u00edfico-filos\u00f3ficos de aquel momento para definir lo que est\u00e1 vivo, es decir, que nace, crece y se reproduce –actualmente los requerimientos son ligeramente distintos y perfilados de otros modos–, lo primero de lo que pod\u00eda afirmarse que lo estaba era la c\u00e9lula<\/strong>. <\/p>\n\n\n\n

Sin embargo, a poco que lo pensemos, esto implica inmediatamente que la c\u00e9lula es algo vivo compuesto por cosas que no est\u00e1n vivas<\/u><\/strong>, ya que la c\u00e9lula tiene partes internas y funcionales que la constituyen (v\u00e9ase en la cl\u00e1sica imagen adjunta). Hoy d\u00eda a nadie le cabe duda de esto –o no debiera caberle, por la obviedad– porque adem\u00e1s sabemos que la materia est\u00e1 formada por lo que hoy llamamos \u00e1tomos y part\u00edculas subat\u00f3micas que tampoco est\u00e1n vivos<\/strong>. <\/p>\n\n\n\n

Todo esto quiere decir que cuando se da la suficiente complejidad funcional de combinaci\u00f3n de sistemas a partir de los materiales b\u00e1sicos e inertes de la realidad –combinatoria restringida por la forma que aporta el n\u00famero–, la vida aparece como lo que llamamos un fen\u00f3meno emergente<\/em>, es decir, un fen\u00f3meno cuyas caracter\u00edsticas s\u00f3lo aparecen como propiedad del sistema y cuyas partes del propio sistema constituyente no lo poseen<\/strong>. As\u00ed pues, \u00abla vida siempre proviene de la no-vida<\/u>\u00bb<\/strong>. <\/p>\n\n\n\n

IS PASTEUR’S IDEA OF THE SO-CALLED \u00abLAW OF BIOGENESIS\u00bb WHICH STATES THAT \u00abALL LIFE COMES FROM LIFE\u00bb, TO WHICH CREATIONISTS Cling, CORRECT?: NO<\/p>\n\n\n\n

\u00abThis idea, very popular for a time, arises as a final conclusion from the demonstration that there was no such thing as spontaneous generation, which had been believed in since Aristotle had formulated it (old Aristotle! The poor man was so lacking in means – -of microscopes in this case– and yet so many interesting but unproven ideas!). Pasteur demonstrated through the microscope that there were small lives, \u00abmicro-bes\u00bb, small living beings that were responsible for generating the decomposition of corpses, and many other things that were suspected but that had not been able to be demonstrated until we could reach, thanks to science, that technological phase.<\/p>\n\n\n\n

That said, it is no less true that that leading phrase, \u00aball life comes out of life,\u00bb should not have been formulated in this way by popular imagery — Pasteur and his colleagues knew very well that what they wanted to refer to was not exactly what that that inappropriately famous phrase said as a supposed summary–, but then, at that time, it was thought in general that life actually always came from life and that is why no one objected to the evident inadequacy of its content.<\/p>\n\n\n\n

Some time later, when science, continuing to collaborate in the development of technology, provided itself with even better means to study matter, it was established that the unit of life was the cell (cell>cell<\/em>>cell , \u00absmall cell\u00bb, in Latin). This means that according to the scientific-philosophical requirements of that moment to define what is alive, that is, what is born, grows and reproduces – currently the requirements are slightly different and outlined in other ways -, the first of the that could be said to be was the cell.<\/p>\n\n\n\n

However, if we think about it, this immediately implies that the cell is something living made up of things that are not living, since the cell has internal and functional parts that constitute it (see the classic attached image). Today no one has any doubt about this – or should not, because it is obvious – because we also know that matter is made up of what we today call atoms and subatomic particles that are not alive either.<\/p>\n\n\n\n

All this means that when there is sufficient functional complexity of combination of systems from the basic and inert materials of reality – combinatorics restricted by the form provided by number – life appears as what we call a phenomenon. emergent, that is, a phenomenon whose characteristics only appear as a property of the system and whose parts of the constituent system itself do not possess it. Thus, \u201clife always comes from non-life.\u201d<\/p>\n\n\n\n
