ABSTRACT
The less attributed to genetic information for determining the development of an organism, the more feasible the study of its evolution. An evolutionary explanation does mean, that a broader perspective must be entertained, a matter that relates to Gould's "adaptive triangle", whose resemblance to Chomsky's "three factors of language design" is clear. Three factors are the functional angle, the historical angle and the structural angle. Minimalist Program can be pushed to the limit of the Strong Minimalist Thesis, thereby inviting us to concentrate more on third-factor considerations than anything else in the triangle. The most basic combinatorial procedure in human syntax, Merge, can be used to illustrate the scope of third-factor considerations, within the Gould/Chomsky evolutionary triangle. The speculation leaves context-sensitivity as the truly unique human evolutionary step. Logically speaking, it could have emerged from more than one source.
