Despite the difficult relations between the natives and the new Europeans, some cooperation was in evidence. The Spanish were shown by the natives how to nurture tobacco and consume it in the form of cigars. There were also many unions between the largely male Spanish colonists and indigenous women. Modern-day studies have revealed traces of DNA that renders physical traits similar to Amazonian tribes in individuals throughout Cuba, although the native population was largely destroyed as a culture and civilization after 1550. Under the Spanish New Laws of 1552, indigenous Cuban were freed from "encomienda", and seven towns for indigenous peoples were set up. There are indigenous descendant Cuban (Taíno) families in several places, mostly in eastern Cuba. The indigenous community at Caridad de los Indios, Guantánamo, is one such nucleus. An association of indigenous families in Jiguani, near Santiago, is also active. The local indigenous population also left their mark on the language, with some 400 Taíno terms and place-names surviving to the present day. The name of "Cuba" itself, "Havana", "Camagüey", and many others were derived from Classic Taíno, and indigenous words such as "tobacco", "hurricane" and "canoe" were transferred to English and are used today.
