Biosemiotics, as described by wikipedia, is:
What are your thoughts on this?
Is biosemiotics a plausible perspective or not?
From what I've read so far, also in other sources, it is not opposed to neodarwinism and they can go hand in hand together. Yet I've also come across this paper which claims that when looked at life from a biosemiotic perspective, it disproves neodarwinism:
To define biosemiotics as “biology interpreted as sign systems” is to emphasize not only the close relation between biology as we know it (as a scientific field of inquiry) and semiotics (the study of signs), but primarily the profound change of perspective implied when life is considered not just from the perspectives of molecules and chemistry, but as signs conveyed and interpreted by other living signs in a variety of ways, including by means of molecules. In this sense, biosemiotics takes for granted and respects the complexity of living processes as revealed by the existing fields of biology - from molecular biology to brain science and behavioural studies - however, biosemiotics attempts to bring together separate findings of the various disciplines of biology (including evolutionary biology) into a new and more unified perspective on the central phenomena of the living world, including the generation of function and signification in living systems, from the ribosome to the ecosystem and from the beginnings of life to its ultimate meanings.
Traditional biology (and philosophy of biology) has seen such processes as being purely physical and, being influenced by a reductionist and mechanist tradition, has adopted a very restricted notion of the physical as having to do with only efficient causation. Biosemiotics is an attempt to use the concepts from semiotics to answer questions about the biologic and evolutionary emergence of meaning, intentionality and a psychic world; questions that are hard to answer within a purely mechanist and physicalist framework.
Biosemiotics may help to resolve some forms of Cartesian dualism that is still haunting philosophy of mind. By describing the continuity between matter and mind, biosemiotics may also help us to understand higher forms of mind.

From what I've read so far, also in other sources, it is not opposed to neodarwinism and they can go hand in hand together. Yet I've also come across this paper which claims that when looked at life from a biosemiotic perspective, it disproves neodarwinism:
The first part of this article supports Margulis theory of symbiogenesis (Serial Endosymbiotic Theory) but questions the use of classical mechanistic language of natural science in describing highly complex interactions of symbiosis and, subsequently, of symbiogenesis. The alternative is to describe these as communication processes which are multi-leveled, regulative, constitutive and generative and whose success depends on sign processes which proceed in a rule-based manner.
The relation between organisms and matter is one of organisms structuring their non-biological environment according to biological principles. The relationship to other organisms is a communicative one: their mutual behavior underlies changeable rules (within the frame of natural laws), more precisely (semiotic) rules of sign use with which the biological individuals interact, i.e. coordinate and organize. The relationship of sign users and sign interpreters to the rules of sign use is not strict and immutable, but rather is changeable, alterable and renewable, although it can ensure relative stability.
The organization of life depends on successful intra-, inter- and metaorganismic communication processes. Interestingly, rule governed sign mediated interactions are not only the basis for human communication and coordination but a true principle of life itself. As demonstrated, it is the main principle also in and between microbial as in higher eukaryotic organisms as well as between organisms of different organismic kingdoms.
The structure of the genome itself is a linguistic one, more analog in eubacteria, more symbolic in archaebacteria and (higher) eukaryotes. It obeys syntactic, semantic and pragmatic rules. Interestingly the neodarwinistic paradigm of chance mutations and selection is refuted nowadays through research results which identify a higher order regulation code in the non-protein coding regions of genome architecture. This higher order regulation code is subject/object to environmental influences which become hereditable, with the effect that a different use of protein coding core components leads to different genetic organization.

This changes our perception about the function and sense of evolution dramatically: No longer are small steps involving chance mutations responsible for differentiating eukaryotic organismic kingdoms, whose phenotypes were then subject to selection pressure. What numerous researchers always surmised, i.e., that chance mutations could not have brought about the enormous complexity of intracellular processes or this astounding diversity of organisms, has proven true. The arguments of neo-Darwinism, that have vehemently defended this monistic (mutation/selection-)evolution over more than half a century, lose their validity. Mutations do occur, but they do not lead to a higher development of organisms, but rather to adaptational variants. They are fine-tunings and not originating factors for de novo evolution.
The SET consciously sets aside the explanation of the origin of the first life-forms or protocells. The true nature of evolution from the beginning, namely as a language-like structured and communicatively organized process, provides good reasons for the thesis that even the de novo origin of life itself coincides with the genesis of rule-governed, sign-mediated interactions.
