Techne and Evolution

Traditionally, Reason is conceived to be possessed by humans and divine beings, but nothing else, notably animals.  Usually, it is a variety of Theoretical Reason, and also Kantian Pure Practical Reason.  But it is difficult to deny that other species possess Techne, e. g. the construction of shelter.  Granted that attribution, the relation between humans and other animals is a greater degree of diversity of Techne, to a large extent facilitated by the superior versatility of the thumbs.  So, it is in the context of Evolutionism that the value of Techne can be best recognized.  At the same time, the evolutionary value of other varieties of Reason, especially Theoretical ones, is less clear than their value in those traditional contexts.
