**2. Methodology**

The review of coevolutionary concepts helps to integrate the human ecological approach, the neoevolutionary school of social and cultural anthropology, and the Actor-Network theory in the so-called M-E-O framework. The efforts to integrate archaeogenetic information about the population and memetic aspects of language history; analysis of sociocultural aspects of reproduction with special regard to culture of attachment, and finally a genetic/memetic system's response to catastrophes like COVID-19 in a coevolutionary framework help to draw a common basis for human ecological understanding of biocultural adaptation and selection.
