Document Summary

Prediction: parental love should have evolved to allocate parental resources optimally. Invest in offspring that are best able to convert parental invest into offspring reproduction. Especially: care more for more offspring than others" offspring. Baby born dead- would expect parents to invest in that child. Prediction: organisms will organize (and favour) their own offspring if theres a risk of misdirecting their parental investment. On the surface it looks like mothers aren"t d and willing to accept any infant placed in their nest. *animals that need to recognize their young as individuals have evolved to recognize their young*- invest inter own offspring an not their neighbours (target parental investment appropriately) Species on cliffs- does not need to recognize as individuals and just needs to recognize its nest (only thing in nest is their own young) - location- based cues work well (defends nest location) Both species invest only in their offspring ,razorbills use location -based cues to.
