Architecture is indeed linked to biology. This observation is intuitively true from a structural perspective, since human beings perceive a kinship between the different processes -- natural and artificial -- that generate form. Nevertheless, the broadness of the claim might appear surprising, considering that it comes from architects holding radically different ideas about what buildings ought to look like. The idea of a biological connection has been used in turn by traditional architects, modernists, postmodernists, deconstructivists, and naturally, the "organic form" architects. One might say that architecture´s proposed link to biology is used to support any architectural style whatsoever. When it is applied so generally, then the biological connection loses its value, or at least becomes so confused as to be meaningless. Is there a way to clear up the resulting contradiction and confusion?
