WebAbstract. The term Darwinian fitness refers to the capacity of a variant type to invade and displace the resident population in competition for available resources. Classical models of this dynamical process claim that competitive outcome is a deterministic event which is regulated by the population growth rate, called the Malthusian parameter. WebThe stronger the selective pressure or the selection event the fewer individuals make it through the sieve of natural selection. Those phenotypes that survive a strong selection event, such as a drought, are a better fit for an environment that suffers drought. Another way to say this is that they have higher Darwinian fitness. WebMultilevel cultural evolutionary theory provides a more general description and rationale for the necessity of system-level selection, enabling previously isolated examples to be compared with each other and the development of a domain-general set of practical tools for going about it ( 14 ). fiware lab login
