There are about 105 males born for every 100 females, but this【B1】______ drops to near balance at the age of maturity, and among 70-year olds there are twice as many women as men. But the great universal of male【B2】______ is being changed. Now, boy babies【B3】______ almost as well as girls do. Fifty years ago, the chance of a baby(particularly a boy baby)surviving depended on its weight. A kilogram too light or too heavy【B4】______ almost certain death. Today it makes almost no【B5】______ . Since much of the variation is due to genes, one more agent of evolution has gone.
There is another way to【B6】______ evolutionary suicide: stay alive, but have fewer children. Few people are as【B7】______ as in the past. Nowadays the number of births, like the age of death, has become 【B8】______ .Again,【B9】______ .
For us, this means that evolution is over; the biological Utopia has arrived. Strangely, it has involved little physical change. No other species fills so many places in nature.【B10】______ . We did not evolve, because machines and society did it for us. Darwin had a phrase to describe those ignorant of evolution: they "look at an organic being as a savage looks at a ship, as at something wholly beyond his Comprehension."

选项
答案
mortality
解析
前句中的among 70-year olds there are twice as many women as men说明,男性的死亡率比女性要高。形容词mortal意为“终有一死的,致命的”,加词缀-ity变为名词mortality“死亡人数,死亡率”,拼写时注意不要与morality“道德”混淆。universal作形容词时意为“普遍的”;作名词时意为“普遍性,普遍现象”。
