What We Inherit Beyond DNA

The way you hold a knife

Watch how someone cuts an onion. If they learned from their mother and she from hers, you're looking at a small, perfect line of inheritance that pre-dates the invention of writing.

Phrases that outlive their speakers

My grandmother's family in southern Italy used a specific curse about goats — three generations later, a great-granddaughter who's never been to Italy mutters it when she drops a pan. The DNA test doesn't catch this. The family tree, done right, does.

Capture the small

When you're interviewing a family elder, ask: "What's a thing your mother used to say when she was frustrated?" Record the answer phonetically if you don't share the language. Some day a great-grand will want to know.
