Niche construction theory (NCT) has become a prominent strain within the "Extended Synthesis" literature in evolutionary biology. Moreover, because human beings are indisputably "the most creative niche constructor", "the ultimate ecosystem engineers", and "the world's greatest evolutionary force", niche construction has been imported to social sciences as social niche construction (SNC) or human niche construction. Yet, NCT has also encountered quite a bit of criticism. If so, what is the value of importing NCT to social sciences as SNC? This article takes the criticisms against NCT and SNC seriously and advances a set of ontological and epistemological principles for applying SNC in social sciences. In particular, I highlight the potential explanatory power of SNC, contending SNC can help us transcend the agent-structure/system debate in social theory, illustrating with Norbert Elias's [1939] 1994a. The Civilizing Process. I also stress that SNC allows us to synthesize micro, meso, and macro for understanding social changes in different niches or domains through time and space, by firmly bringing time and space into theorization in social sciences inquires.
