Hierarchical heterogenity of populations: modeling by the open Eigen hypercycle

The case of a biological population, which consists of sev-eral sub-populations (different kinds of the population ”so-cial” groups: families, bevies, etc.), has been considered. For description of non-trivial interactions between these groups, a model of ”open the Eigen hypercycle” has been
proposed. Its bifurcation analysis for 3-dimension case has been carried out. Ecological interpretation of the results
has been discussed.
