Paras. 7&8
The genetic maps also shed new light on the origins of populations that have long puzzled scientists. Example: the Khoisan people of southern Africa. Many scientists consider the Khoisan a distinct race of very ancient origin. The unique character of the clicking sounds in their language has persuaded some researchers that the Khoisan people are directly descended from the most primitive human ancestors~ But their genes beg to differ. They show that the Khoisan may be a very ancient mix of west Asians and black Africans. A genetic trail visible on the maps shows that the breeding ground for this mixed population probably lies in Ethiopia or the Middle East.
The most distinctive members of the European branch of the human tree are the Basques of France and Spain. They show unusual patterns for several genes, including the highest rate of a rare blood type. Their language is of unknown origin and cannot be placed within any standard classification. And the fact that they live in a region next to famous caves which contain vivid paintings from Europe's early humans, leads Cavalli-Sforza to the following conclusion: "The Basques are extremely likely to be the most direct relatives of the Cro-Magnon people, among the first modern humans in Europe." All Europeans are thought to be a mixed population, with 65% Asian and 35% African genes.
A statement: The genetic maps also shed new light on the origins of populations that have long puzzled scientists.
Example 1:
Many scientists consider the Khoisan a distinct race of very ancient origin, directly descended from the most primitive human ancestors. But the genetic maps show ______ (Para. 7)
Example 2:
The Basques of France and Spain have unusual patterns for several genes and their language of unknown origin cannot be placed within any standard classification. And the fact where they live leads to the conclusion that the Basques are likely to be ______. All Europeans are thought to be a ______. (Para. 8)
