Resumen de La biosemiótica y la biología cognitiva en organismos sin sistema nervioso
Biosemiotics and cognitive biology in organisms without a nervous system.Biosemiotics is a discipline that emerged in the 1960s from studying communication and transfer of signs and signals between animals (zoosemiotic) by the semiologist Thomas Sebeok. Its origin can be placed a hundred years ago in the works of the biologist and philosopher Jakob von Uexküll, who develop a “theory of meaning” (Bedeutungslehre) to describe (with the minimal possible anthropocentricity) how animals perceive their environment and inner world. It is review here the conditions of possibility for cognitive processes in organisms without a nervous system, where some events lead us to propose ways of learning and behavior influenced not only by basic tropisms. We study the biosemiotic cognitive foundations within slime molds and bacteria, in order to establish a possible phenomenological biology, based on the measurement of minimal perception thresholds. Key words: Biosemiotics, transdisciplinarity, cognition, information, Physarum polycephalum, tensegrity, microtubules, haptic perception, tectology, Santiago theory, Weber-Fechner law.
