by 1846, he had published an article describing his voyage. he also began to think seriously about evolution and natural selection, and wrote two essays describing his ideas. he did not publish these essays because he realized his ideas proved the bible’s theory of creation was wrong, and he was worried about the anger and troubles they would cause.
darwin spent the following years developing his theories and making them perfect. in 1859 he published them in the origin of species(《物種起源》). it caused a huge row because it seemed to deny what the bible said. his the descent of man(《人類的由來》), 1871, pointed out that mankind had come from the same ancestor. darwin was upset by the opposition. other scientists agreed with his ideas and took up his cause. the church prohibited the teaching of the theory of evolution(進化論) in some countries. however, today most people believe that darwin was right.
27. miracle in the rice field
it is said that every scientist has a childhood dream for his or her future success. for yuan longpin, known as the “father of hybrid rice(雜交水稻)”, the dream is that he cultivates rice as huge as peanuts, and farmers can have a rest in the cool shadow of big rice plants.
yuan longpin was born into a poor family in 1931. upon graduating from the southwestern agricultural college(西南農業學院) in 1953, he began his teaching career at an agriculture school and has since devoted himself to agricultural education and research.
he came up with the idea of hybrid rice for the first time in the 1960s. in the early 1970s, he succeeded in developing the world’s first high-yield hybrid rice. of great importance is his pioneering work, which has established china’s position of world leadership in this area.
the un food and agriculture organization(fao)(聯合國糧食與農業組織) has decided to get involved in the work of spreading the coverage of yuan’s high-yield hybrid rice, which it considers the best way to increase the world’s grain output.
in the following years, increasing grain output of hybrid rice further showed the success of yuan longpin’s research. this made him firmly believe that china can surely feed her large population with her limited cultivated land.
this breakthrough in rice cultivation has significantly contributed to solving the food problem in china and the rest of the world. yuan’s amazing achievement has won him a great many awards and honours from the united nations and worldwide.
however, even with such a great achievement, yuan won’t take a break. in his mind there always exist a dream, more practical than that of his youth, that popularizing the new hybrid rice with higher yields around the world can eliminate starvation on earth. “if the new hybrid rice were grown in the world’s remaining fields, the present grain output around the world would be more than doubled. this can solve the grain shortage,” said the scientist.
