Parent-Offspring Conflict
Shared genes create overlapping but not identical evolutionary interests.
The Mechanism: Parent-offspring conflict theory describes evolutionary disagreements over resource allocation because a parent and each child share genes but are not genetically identical. The model predicts potential conflicts around investment, timing, and independence.
The Philosophical Pivot: A biological model of differing interests does not mean families are inevitably hostile. It describes a possible tension in reproductive allocation, not the emotional meaning of a relationship.
The Horizon: Understanding conflict can illuminate why care and autonomy sometimes pull in different directions. Culture and institutions shape how families negotiate those tensions beyond biology alone.
The theory does not say children are calculating or parents are selfish. It explains how selection can favor different optimal outcomes for each relative.
Shared love can coexist with different needs; recognizing that difference may make care more responsive rather than less real.
Being related can bring people together without making their interests identical.
Where in my closest relationships do I mistake shared love for shared needs?
