Show Notes

Is permanent separation the default setting in nature? We explore the biological mechanisms behind parental separation, contrasting solitary species like sloths with highly social animals like elephants and orcas. The discussion reveals that what humans call "grief" or "longing" is often a survival strategy disguised as feeling. While some species experience deep social bonds and mourning, others operate on pure energetic efficiency, viewing offspring as competitive burdens once they reach independence.
