Niguss' research involves understanding the evolutionary connection between tool making and the human hand, and the influence of the former on changes in human adaptations through time. In this regard, understanding whether or not the derived morphological features evident in the human hand evolved in response to manipulative behavioral activities during stone tool production is the primary focus of his research. He is also intrigued to further understand the relationship between manipulative capabilities associated with the use of non-stone-tool based behaviors and locomotion, especially in relation to the human-like morphological features that emerged prior to the onset of stone tool use.
