To be quite honest, there were many portions of the biosemiotics lecture that I did not understand, however, from what I could take away, it seemed to be an interesting, yet controversial field.  Biosemiotics in general is the study of signs and communicating factors that interplay between life forms. Interactions between both animals and plants have been described as the result of some form of this communication. The evolution and development of the cell is thought to have occurred in a biosemiotic fashion. Personally, the formation of a single cell can and will be forever debated as it is a topic in which variability and uncertainty reign as dominating factors. Another point that was made was the signs and communication between plants and trees of a forest and how that influences growth of the forest as a whole. Biosemiotics claims that similar amounts of carbon is stored in trees of the same forest. This is due to the fact that some form of communication, via signs or other intangible signals, between the trees allows the to remain is similar biotic stages. This is an interesting idea, however, one might argue that trees of the same area have similar life stages because they have been growing under the same environmental conditions and similar time frames. Here is a link on biosemiotics if you’re interested.
