Research has shown that the average height of humans is increasing. In the last 150 years, the average height of men and women has increase an average of 10 centimeters. In the Netherlands, it has actually increased by 25 centimeters. Studies from around the world have confirmed these findings. A number of theories of why humans average height is increasing have been put forward, including improved genetics, maternal care, wealth, education, and housing conditions. However, the most likely reason seems to be better nutrition, and healthier people. Studies of the height of slaves in the United States in the early 1800's and of the French during the food crisis in France in the 1700's are two studies that confirm the tie of height to food, where people who are hungry fail to grow as tall as the people who have better nutrition. |
