It is possible that the core principles of The Faculty of Language be correlated to natural laws (such as for example, the Fibonacci sequence— an array of numbers where each consecutive number is a sum of the two that precede it, see for example the discussion Uriagereka 1997 and Carnie and Medeiros 2005). According to the hypothesis being developed, the essential properties of language arise from nature itself: the efficient growth requirement appears everywhere, from the pattern of petals in flowers, leaf arrangements in trees and the spirals of a seashell to the structure of DNA and proportions of human head and body. Natural Law in this case would provide insight on concepts such as binary branching in syntactic trees and well as the Merge operation. This would translate to thinking it in terms of taking two elements on a syntax tree and such that their sum yields another element that falls below on the given syntax tree (Refer to trees above in "Minimalist Program"). By adhering to this sum of two elements that precede it, provides support for binary structures. Furthermore, the possibility of ternary branching would deviate from the Fibonacci sequence and consequently would not hold as strong support to the relevance of Natural Law in syntax.
