What is the impact of the theory of frozen plasticity on taxonomy?
The theory of frozen plasticity suggests that the taxonomic category of species, and even more that of genus, could objectively denote the existing entity, rather than a merely useful epistemological construct of biologists. Within the theory of frozen plasticity, a biological species can be defined as a set of individuals sharing an identical gene pool throughout the period between two speciating events. Similarly, a genus can be defined as a set of individuals sharing a common exclusive ancestor in the time between two periods of evolutionary plasticity.
