Mendelian Inheritance Law and Biometry, also prove evolution impossible. The unity of mankind is also conclusively shown by the fact that all races interbreed, the most certain test of every species. All these facts pointing to the unity of the race in the days of Noah and of Adam are irreconcilable with the theory of evolution which denies that unity within the last two million years. We shall present these arguments more in detail. The arguments immediately following, especially the first eight, show the unity of the human race in the days of Noah, and thus present insuperable objections to evolution, and confirm the story of man’s creation and his destruction by the flood. The following is the first of fifty Arguments against the evolution of man. 1. THE POPULATION OF THE WORLD The population of the world, based upon the Berlin census reports of 1922, was found to be 1,804,187,000. The human race must double itself 30.75 times to make this number. This result may be approximately ascertained by the following computation:— At the beginning of the first period of doubling there would just be two human beings; the second, 4; the third, 8; the fourth, 16; the tenth, 1024; the twentieth, 1,048,576, the thirtieth, 1,073,741,824; and the thirty-first, 2,147,483,648. In other words, if we raise two to the thirtieth power, we have 1,073,741,824; or to the thirty-first power, 2,147,483,648. Therefore, it is evident even to the school boy, that, to have the present population of the globe, the net population must be doubled more than thirty times and less than thirty-one times. By logarithms, we find it to be 30.75 times. After all allowances are made for natural deaths, wars, catastrophes, and losses of all kinds, if the human race would double its numbers 30.75 times, we would have the present population of the globe. Now, according to the chronology of Hales, based on the Septuagint text, 5077 years have elapsed since the flood, and 5177 years since the ancestors of mankind numbered only two, Noah and his wife. By dividing 5177 by 30.75, we find it requires an average of 168.3 years for the human race to double its numbers, in order to make the present population. This is a reasonable average length of time.
