Evolutionary biology and beliefs : how ideology can draw different social stances from science

Agreeing that there are often strong connections between fields of science and the ideological convictions of those producing the science, this essay shows that the connections are often complex and rarely straightforward. Taking the example of evolutionary biology, by looking at three key figures ? Herbert Spencer, Charles Darwin and Alfred Russel Wallace ? it is shown how very different social beliefs can lead to very different social conclusions being drawn from one?s science. It is argued that this message should be kept firmly in mind by those who today would draw social conclusions from science, for instance suggesting that Darwinian evolutionary biology leads straight to the social philosophy of the Third Reich. The truth is always far more complex

¿Por qué el estegosaurio tiene placas, o es la biología una ciencia de segunda clase porque piensa en términos de fines?

There is something distinctively different about explanation in the biological sciences, as opposed to explanation in the physical sciences. In the former one has functional arguments, arguments making reference to what Aristotle called “final causes.” As in: “The function of the plates on the back of the Stegosaurus was to keep the body at a constant temperature.” Since the Scientific Revolution, such explanations have been forbidden in the physical sciences. Does this then mean that biology is second rate, as is suggested by many including Immanuel Kant? It is argued that the Darwinian mechanism of natural selection explains why there is need of functional explanation in biology and that once this point is grasped, there is no reason to judge biology second rate.Hay algo distintivamente diferente en la explicación propia de las ciencias biológicas, en tanto opuesta a la explicación en las ciencias físicas. En las primeras tenemos argumentos funcionales, argumentos que hacen referencia a lo que Aristóteles llamó “causas finales”; por ejemplo, “La función de las placas de la parte posterior del estegosaurio era mantener el cuerpo a una temperatura constante”. Desde la Revolución Científica, explicaciones de este tipo han sido prohibidas en la física. ¿Significa esto que la biología es de segunda clase, como sugieren algunos, entre ellos Immanuel Kant? Se defenderá en este artículo que el mecanismo darwiniano de selección natural explica por qué hay necesidad de una explicación funcional en biología y, que una vez que se comprende este punto, no hay razón para juzgar a la biología como ciencia de segunda clase

Evolution and Creationism in America's Classrooms: A National Portrait

Despite many legal and legislative decisions, a new study shows that one in eight high school biology instructors teach their students that creationism or intelligent design is a valid alternative to evolutionary biology
