(选择) . It turns out human selection can also cause plants to evolve.
Take the case of the snow lotus, a rare(稀少的) plant that grows only high up in the Himala-yas. Researchers have discovered that one type of the plant has been becoming smaller over time
——the one people like to pick.
A type of snow lotus called Saussurea laniceps is used in Tibetan and Chinese medicine and is increasingly demanded by tourists. The largest plants are picked, and that occurs during their only
flowering period.
The result is that only smaller, unpicked plants go to seed. Selection caused by humans is a powerful force, according to some scientists. They studied the plants picked over time and also compared the snow lotuses growing in heavily harvested areas with those found in places where peo-ple rarely picked them.
They reported in an article that the heavily harvested snow lotuses have been getting shorter o-ver the last century, while those in areas not picked have remained the same. They found that in the heavily harvested areas, where only the smaller plants got to reproduce, the average height was 5.3 inches. The same plants in rarely harvested areas averaged 9 inches in height. And they noted that another type of snow lotuses which is not often picked, has not been changing.

The success story started in northern Italy towards the end of the Second World War. Leone Benetton had a bicycle rental(租赁)business in the town of Treviso. He wanted his oldest son Lu- ciano to study and become a doctor. After Leone died, the family was poor and Luciano decided to leave school and get a job. He found work in a clothing store but soon had his own ideas and star-ted a family clothing company producing colourful woollen sweaters for people only used to wearing dull colours. Shops selling only Benetton sweaters opened in many Italian cities and by 1974 therewere stores in France, Gemany and Belgium.
It was clear that at this stage the success of the Benetton business lay in the strength of the family. In 1975 Luciano married the 20-year-old Marina Salomon who worked in one of his shops. Af-ter careful research, Benetton opened his first shop in the USA, in Manhattan, New York, where it attracted some very special customers including Princess Diana and Jackie Onassis. In 1982 Lucianowas introduced to Oliviero Toscani, the photographer who was to change the image(形象) of Be- netton forever.
Although Benetton was growing very quickly, they needed an international image and for thisreason in the early l980s they decided to provide money for Formula l motor-racing. This was fol-lowed by the advertising campaigns(广告攻势) for which the company became famous.
Luciano Benetton succeeded in turning the company he started in the l950s into one of the world' s most successful businesses but he paid a high personal price. He spent so much of his life working and travelling that he lost touch with his family and friends.
