There are about 105 males born for every 100 females, but this (36)______ 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 (37)______ is being changed. Now, boy babies (38)______ 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 (39)______ almost certain death. Today it makes almost no (40)______. Since much of the variation is due to genes, one more agent of evolution has gone.
There is another way to (41)______ evolutionary suicide: stay alive, but have fewer children. Few people are as (42)______ as in the past. Nowadays the number of births, like the age of death, has become (43)______. Again, (44)____________.
