In 1891 Cambridge biologist William Bateson (1861–1926) announced his idea that the symmetrical segmentation in living organisms resulted from energy peaks of some vibratory force acting on tissues during morphogenesis. He also demonstrated topographically how folding a radially symmetric organism could produce another with bilateral symmetry. Bateson attended many lectures at the Cambridge Philosophical Society and viewed mechanical models prepared by eminent physicists that illustrated how vibrations affected materials. In his subsequent research, Bateson utilized analogies and metaphors based upon his (...) observations of nature to build a thought model on the effects of vibrations on living tissue, because he realized that the chemistry and biology of his day lacked technologies to perform actual experiments on the subject. He concluded the production of organic segmentation was both a chemical and mechanical phenomenon. By the time of his death Bateson had incorporated new ideas about embryonic organizer regions to suggest a center from which a rhythmic force emanated and then produced the observed repetitive segmentation as a common feature in living organisms.

Emphasis on cutting edge science is common today. This paper shows that the concept, which selects some science at any given time as epistemically preferable and therefore better, actually gained acceptance by the turn of this century in biology and began immediately to have consequences for what biological research was done. The result, that some research is cut out while other work is privileged, can have pernicious results. Some of what is designated as not cutting edge may, in a different (...) — and equally defensible epistemological framework, prove just as good as the officially cutting edge research. Cutting edges cut both ways, and those who study science should begin exploring the implications of that fact. (shrink)
