“The changes that took place in the habits of the people in respect to eating, walking and other things, reacted upon their physical development, slowly and imperceptibly, however, unless comparisons were made between people of several generations apart. The tendency as you know, is, toward the suppression of organs not habitually used. Use and habit keep all organs in good running order and develop them in size and health, whereas disuse allows them to become shriveled and reduced, and if it is persisted in for too many generations the organ will be reduced to an unrecognizable functionless remnant or disappear altogether. All animals including man have lost organs by ceasing to use them. Very many, as the ox, sheep, dog, deer etc., have lost toes, many have lost part of their intestines, some have lost a part or the whole of one lung. Most vertebrates including man were derived from ancestors who once possessed—but lost—an eye on the back of the head. The whales and snakes have lost their legs and feet in whole or in part. “You will not be surprised therefore to be told that the man of the second millennium began to be perceptibly changed from the one you knew in the 19th century. But when we come to the tenth millennium the change is astonishing. Let me describe him. “His average height is eight inches less. His legs are short and spindling, his feet are small, and his toes reduced to small nubbins or mere warts. He has no teeth and the males and third sex people have not hair enough to make a scalp lock, even among the young, and it all disappears before middle age. The females however still maintain enough for a few bangs and spit curls. The external ears are reduced to a low rim of cartilage around the opening, about one inch in diameter. The lower part of the trunk is small and weak. The upper part containing the heart and lungs is, however, very well developed. The arms and hands are well formed strong and symmetrical. The head is very large indicating large mental power. All these deviations from the average man of your day became more pronounced with time, and if you could see a man of the one hundredth millennium you would have to inquire what it was. His stature now is but four feet, twelve inches of which is head, eighteen inches trunk, and the other eighteen inches legs. His chest is very broad, and very thick from front to back. His arms are stout and long enough to allow him to reach to his knees while standing. They are much larger and stronger than his legs. He is bald as an orange from birth. He has an immense mouth which he uses much in singing, laughing and speaking. He has not the vestige of an external ear nor any hair on any part of the body. No teeth of course and no sign of a toe. The foot is also much shortened and his walk is neither graceful nor vigorous. Foot ball is no longer his best hold, although his ancestor in your day may have belonged to the Sophomore foot ball eleven, of the Minnesota University.
