Did you know people who live in different parts ofChinahave different habits and preferences? For example,
people from southernChinaprefer to eat vegetables, while people from northChinalike to eat meat. According to a
new study in a journal, gene variations (变异) might be responsible for these differences. Researchers fromChina’s
BGI collected genetic information from 141,431 Chinese women, who came from 31 provinces and consisted of 36
ethnic minority groups.
They found that natural selection has played an important role in the ways that people living in different
regions of China have developed, affecting their food preferences, immunities (免疫力) to illness and physical
features.
A variation of the gene FADS2 is more commonly found in northern people. It helps people metabolize (新陈代谢) fatty acids, which suggests a diet that is rich in flesh. This is due to climate differences.Northern Chinais at a
higher latitude. This weather is difficult to grow vegetables in. Therefore, northerners tend to eat more meat.
The study also found differences in the immune systems of both groups. Most people in southernChinacarry
the gene CR1, which protects against malaria. Malaria was once quite common in southernChina. In order to
survive, the genes of people in the south evolved to fight against this disease. However, people in the south are
also more sensitive to certain illnesses, as they lack the genes to stop them.
Genes can also cause physical differences between northerners and southerners. Most northerners have the
ABCC11 gene, which causes dry earwax, less body smell and fewer sweats. These physical differences are also
more beneficial to living in cold environments. Southerners are less likely to have this gene, as it did not develop in
their population.
4. What did the new study focus on? A. Regions. B. Eating habits.
C. Gene variations. D. Ethnic minority groups.
5. What is the main function of the gene FADS2?
A. It helps store fat. B. It helps digest meat.
C. It helps gain weight. D. It helps treat an illness.
6. According to the study, most northerners ________.
