Darwin i l'evolució Agustí, J. Patrons
evolutius i progrés biològic Evolutionary patterns and biological progress Since its very beginnings, evolutionary change has been associated with the idea of progress. This is true even for Darwin, who in principle was against this association. This opinion was much more propounded by other Darwinians of that time, such as Ernst Haeckel. The idea of evolutionary progress is also shared by the principal authors of modern synthesis, such as T. Dobzhansky o G. Leydard Stebbins. In its relationship to the ongoing crisis in the human sciences, the idea of progress was also attacked by evolutionary biologists during the latter part of the XX century, most notably by Stephen J. Gould. In this article we propose that biological progress is not only applicable to certain evolutionary processes, but that it can also be linked to the external inputs of energy within the Earth system. |
