In ecology, speciation describes the process through which a new natural species may emerge as a sub-population adapts to new ecological conditions (dupre,´ 2001) technological speciation refers to a new tech-nology that emerges as an existing technological form is adapted to a new selection environment (levinthal, 1998.
