Many would say that we simply do not have enough data to answer the question of our origins and that with the eventual accumulation of more data, many MHO issues will be resolved.
Insufficient data is only part of the answer, however.
MHO researchers come from various research traditions. In each of these traditions, different assumptions about the remote human past determine what is considered relevant data, which questions are asked of the data, and how the data are interpreted. More data do not remove the paradigmatic bias implicit within each research tradition, and in consequence people from different fields fail to communicate effectively. Although these observations apply to all aspects of MHO research, MHO archaeology in Europe is a particularly good example of such epistemological na vete. However, such a critically self-conscious approach is often lacking.
