Predictions from a theory assuming mate selection on the part of females, which maximizes reproductive success of individuals, are found to accordance closely, though not completely, with known mating patterns. These predictions are that (1) polyandry should be rare, (ii) polygyny should be more mutual among mammals than amid birds, (3) polygyny should be more prevalent among precocial than among altricial birds, (four) atmospheric condition for polygyny should be met in marshes more than regularly than amongst terrestrial environments, (five) polygyny should exist more prevalent among species of early on successional habitats, (6) polygyny should be more prevalent among species in which feeding areas are widespread simply nesting sites are restricted, and (7) polygyny should evolve more than readily among species in which clutch size is strongly influenced by factors other than the ability of the adults to provide food for the young. Most cases of polygyny in birds, a grouping in which monogamy is the most common mating design, can be explained on the basis of the model, and those cases not apparently plumbing fixtures into the predictions are conspicuously indicated. Thus, there is no need at nowadays to invoke more complicated and restrictive mechanisms to explicate the mating patterns known to be.
