Origin of descent
Though the word descent has been around for over half a millennium, some of its early senses are still in use. In the 1330s one use of descent described familial ancestry. Darwin popularized and expanded this term in Victorian England with his study of the origins of humans and our simian relatives from a common ancestor. This sense is very familiar to speakers of current English who have studied natural history. We also often hear descent in the context of ancestry such as “African descent” or “Scandinavian descent.” Another early use describes an object moving from a higher position to a lower position. Today, we still use this sense when talking about the downward movement of an airplane as it prepares to land. In religious contexts, one might hear about the Descent of Christ into Hell, a sense first appropriated in the 19th century.
Be careful not to confuse descent with decent. While it’s easy to leave out just one “s,” people are sure to express dissent (another word not to be confused with descent ) with your diction.

c.1300, from Old French descente "descent, descendance, lineage," formed from descendre (see descend) on analogy of French nouns such as attente from attendre "to expect," vente "sale" from vendre "to sell," pente "slope" from pendre "to hang" (the etymological English word from Latin would be *descence).
Figurative use is from late 14c. Meaning "action of descending," also "a downward slope" is from 1590s. Meaning "act of descending from an ancestor" is from mid-14c. Evolutionary sense is from 1859 in Darwin, though there are uses which suggest essentially the same thing going back to 1630s.
