Most of them were domesticated from wild ance::;tons long before the beginning of the hi -toricaJ period, and all available records inelle-ate that they were as familiar to the peoples of the ancient world as they are to us. Comparatively few new plants have been developed during the last 2000 years, although the older ones have been greatly altered and improved in response to the increasing complexity of man's existence. The history of our utleful plant::; and their influence on civilization has always been of interest to botanists and ethnologists. Many investigations have been carried FIG.

So careful and painstaking was his work that few of his conclusions have had to be altered in the light of more recent studies. D e Candolle (Fig. 127) based his conclusions on a great variety of evidence : the works of Theophrastus, Dioscorides, and other old historians; Chioese writings; arc:heological and ethnological data, such as the monuments of Egypt, the ruins of Pompeii, the remains of the Lake Dwellers of 297 • 298 ECONOMIC BOT ANY Europe, and the Inca ruins of South America; philological indications, involving the names of plants in Hebrew, Sanskrit, and other ancient languages; and botanical conclusions based on distribution, number of varieties, presence or absence of wild types, length of cultivation, and similar matters.
