Evolutionary theory of technological change: State-of-the-art and new approaches Tessaleno C. Devezas Technological forecasting and Innovation theory Working group, University of Beira Interior, Covilha, Portugal Received 13 may 2004;

After some introductory thoughts in the first part, it is tried in the second part to summarize in five points some of the still missing pieces to complete the puzzle to developing a firmly based Evolutionary theory of technological change (ETTC.

The development of a working ETTC bears the correct understanding of three difficult-to-define concepts,

This barrier must be overcome to constructing a working ETTC. It does not make sense to develop an ETTC starting from the analogies

and/or disanalogies found between biological and techno-cultural evolution, or in other words, between the evolution of organisms and artifacts.

In the points below I try to resume some important aspects that were considered never consistently in the attempts of model building of an ETTC:

With this short collection of ideas I wish to suggest that a firmly conceptually based danthropology of techniquet is still lacking in the current attempts of model building and formal theorizing of an ETTC.

or in other words, the basic process of Gene Culture Coevolution, which is the most appropriate approach to develop a firmly based ETTC.

T. C. Devezas/Technological forecasting & Social Change 72 (2005) 1137 1152 1148 Although a consistent ETTC still not exists

As a first step toward a research agenda for future development of TFA I propose the realization of an international seminar in this field (Evolutionary theory of technological change) bringing together specialists in evolutionary model building and digital Darwinism to discuss the existing approaches
