The Science of Survival: Why Animals Abandon Their Young
The article explains why mother animals in the wild sometimes abandon their offspring: it is an evolutionary strategy to conserve resources and ensure the survival of the fittest. Examples include birds regulating brood size and mammals rejecting a single offspring due to inexperience or extreme conditions. Epigenetic transmission of trauma is also mentioned.
An article on the Cursorinfo portal explains why animals in the wild abandon their young, presenting it as an evolutionary survival strategy. It cites the example of a Japanese macaque infant named Punch, who was rejected by its mother but found comfort in a stuffed toy. Biologists note that such behavior is common and has pragmatic reasons. In birds like light-footed shearwaters, brood size regulation occurs: when resources are scarce, they feed only the strongest chicks, increasing female survival by 16%. In mammals, rejection of a single offspring can be due to the mother's inexperience, extreme conditions (heat, food scarcity), or concern for her own health—observations of night monkeys show that females that forgo nursing live on average four years longer. Epigenetic memory is also mentioned: 'rejects' raised in captivity often repeat the pattern and abandon their own offspring. The article references a publication in Discover Wildlife.
