When an adult becomes a parent or caregiver, the direction of a life changes again. The person who spent childhood receiving capability now begins transmitting resources, knowledge and care to someone else.

Not everything passed on is the same

Genetic information travels biologically. Language is learned. Money and property are transferred through social and legal arrangements. Habits are copied. Knowledge can be taught. Connections and location can alter which opportunities are easiest to reach.

Calling all of this “inheritance” can make the story sound simpler than it is.

Transmission can help or harm

Families can pass down strong learning routines, practical knowledge and financial buffers. They can also pass down misconceptions, unstable routines or constraints. Institutions and environments can reinforce or counter these effects.

A human becomes part of civilisation’s continuity

Adults also transmit capability outside their families. A worker trains a colleague. A teacher teaches a class. A craftsperson shows an apprentice. An experienced employee carries knowledge that may not exist in any manual.

Across millions of ordinary people, civilisation continuously reproduces itself through these transfers.
