Re-semblance and re-evolution: Paramorphism and semiotic co-option may explain the re-evolution of similar phenotypes.
The independent emergence of similar features in phylogenetically nonallied groups of organisms has usually been explained as the result of similar selection pressures particular to specific environments. This explanation has been more or less helpful in elucidating convergent resemblances among org...

This explanation has been more or less helpful in elucidating convergent resemblances among organisms since the times of Darwin. Nevertheless, intensive research has brought new knowledge on the emergence of structural similarity among organisms, especially during the last two decades. We now have manifold evidence of the phenomena of evolutionary re-entries or re-evolution, which happens when a particular character present in one organic taxon also appears in another taxon which does not share an immediate ancestry. This is not the re-appearance of the same character, but rather of a similar one. Here I propose a model of threefold origin of similar phenotypic features in unrelated organisms stemming from intrinsic, extrinsic and semiosic causation. It is suggested that neither externalist nor internalist explanations per se, nor any combination thereof, are sufficient to cover all the manifold instances of character re-evolution. There is also a special group of resemblances that consists of what is originated, shaped, and retained in evolution due to meaning attributed to them by particular organic subjects. These cases cannot be fully understood without inviting a biosemiotic approach. Integrating Uexkull's theory of meaning with the recent evolutionary developmental perspective could complete our understanding of phenotypic re-evolution. pubtype: Academic Journal doctype: Essay src: R language: English refInfo: copyright: @attributes: flag: Y custom: Copyright of Sign Systems Studies is the property of University of Tartu and its content may not be copied or emailed to multiple sites without the copyright holder's express written permission.
