“The word for children and grandchildren literally means 'climbing down' — because the Romans imagined family trees growing upward, with the founders at the top and the descendants descending.”
Latin descendentem (present participle of descendere) means 'climbing down,' from de- ('down') and scandere ('to climb'). The genealogical metaphor is spatial: ancestors are above, descendants are below. A family tree grows upward toward its roots. The descendant climbs down from the origin. The spatial logic is the opposite of a biological tree, where roots are underground and branches grow up.
The word entered English from Old French descendant in the 1300s. It immediately carried both the physical meaning (going downward) and the genealogical meaning (offspring of an ancestor). English has used 'descendant' and 'descendents' as variant spellings for centuries; the -ant ending (from the Latin present participle) is now standard.
The concept of descent became politically loaded in the 18th and 19th centuries. 'Descent' determined inheritance, citizenship, and caste in many legal systems. 'Descent with modification' was Darwin's own phrase for what we now call evolution — he used the family-tree metaphor to describe how species change over generations. Biological descent and genealogical descent merged in a single word.
DNA testing has transformed the meaning of descendant. Since the early 2000s, companies like 23andMe and AncestryDNA have offered genetic testing that traces descent through maternal (mitochondrial DNA) and paternal (Y-chromosome) lines. The word that was once about family stories and legal documents now also refers to molecular sequences. The climbing-down can be measured in base pairs.

Everyone alive today is a descendant of a remarkably small number of ancestors. Mitochondrial Eve — the most recent common maternal ancestor of all living humans — lived roughly 200,000 years ago in Africa. Every human on earth descends from her. The climbing-down from a single point in Africa covers every person, every language, every culture.
The DNA test tells you where your ancestors climbed down from. But the word itself contains a quiet spatial error: it assumes the past is above us. It is not. It is behind us, beneath our feet, in the ground. We do not descend from the past. We carry it.
