Evolutionary Concepts Defining Speciation: BSC and Recognition concept Species are produced by individual speciation events‚ so a single species concept can’t be defining all species. Hugh Paterson’s ideas are significant in understanding evolution. Paterson argues that speciation is not an adaptive process‚ but is a result of the adaptation of intricate bonding mechanisms to a new environment (Paterson). The conceptual basis of his research is the Recognition Concept of Species. He argues that
