Evolution

Because the late Dr. William T. Brigham, director of physical education at Harvard University, took measurements of some 2,000 Harvard students between 1870 and 1880, it has been possible by measuring later students to discover a distinct change in size, an evolutionary trend. Last week Gordon Townsend Bowles, graduate anthropology student, revealed results of his study of measurements of Harvard men, including figures for 400 pairs of fathers and sons--first such comparison thus to be made. Present day Harvard men. the figures show, are on the average eight pounds heavier than their fathers were. Their average height of 5 ft. 10 1/10 in. represents a group increase of one inch over a period of 32 years. Their hips are slimmer, their torsos and shoulders heavier.

Measurements of 501 pairs of daughters and mothers who attended Smith, Vassar, Wellesley and Mt. Holyoke Colleges show a similar trend. The girls are some seven pounds heavier, about one inch taller than were their mothers at the same age. They are larger in every way but one: their hips are more slender.
