4. If the human race doubled its numbers every 168.3 years since Noah became a father (5177 years) what would be the population of the globe? Ans. 1,804,187,000,—just what it is.
5. If the Jews doubled their numbers every 161.251 years since Jacob’s marriage (3850 years ago), how many Jews would there have been in 1922? Ans. 15,393,815, just the number reported.
6. What guess of man’s age can stand the test of mathematics? Ans. Not a single guess ever made assigning a great age to man,—nothing greater than the age indicated by the Scriptures; 2,000,000, or 1,000,000, or 100,000 years are clearly out of the question.
7. If life began 60,000,000 years ago, and the human race 2,000,000 years ago, how much sub-normal should have been the brain and mind of man at that time? Ans. 1/30 or 3-1/3%; or 96-2/3% normal; or 1450 c.c., counting 1500 c.c. normal,—more nearly normal than many nations now.
8. How much if life began 500,000,000 years ago? Ans. .4%; or 99.6% normal; or 1494 c.c., far more c.c. than a large part of mankind can claim.
9. If man had, in 58,000,000 years, developed only the same skull capacity as the other members of the simian family (not over 600 c.c.), how much must he have gained in 2,000,000 years? Ans. 900 c.c., which is a development 43.5 times as rapid in 2,000,000 years as in the 58,000,000 years preceding. How could that be?
10. If life began 500,000,000 years ago, how would the rapidity of skull and brain development in 2,000,000 years compare with that of the 498,000,000 years preceding? Ans. 373.5 times as great.
11. If the skull of the pithecanthropus was two-thirds normal, or 1000 c.c., how many years ago must it have lived, in case life began 60,000,000 years ago? Ans. 20,000,000; in case life began 500,000,000 years ago? Ans. 166,666,666.
12. If the Piltdown “man” had a normal skull capacity of 1070 c.c., as claimed, how long ago did he live, if life began 60,000,000 years ago? Ans. 17,200,000 years. If 500,000,000 years ago? Ans. 143,333,333 years.
13. If the Neanderthal man had a capacity of 1408 c.c. (assigned by Dr. Osborn), how many years ago must he have lived if 60,000,000 years have passed since life began? Ans. 3,680,000; if 500,000,000 years? Ans. 30,666,666. If 1800 c.c. be taken as normal instead of 1500 c.c. as some insist, these great periods since these “ape-men” existed must be enormously increased, in some cases 50%.
