Document Summary
Big and small things often don"t resemble each other because large animals have big bones, and small animals have small bones. The reason has to do with the strength of materials and how much weight they can support (e. g. Robert wadlow, the tallest man, died at age 22 because he"s knees could not support his weight. ) The dominance of gravity and the importance of self-gravity". Gravity plays a big role in the example of large animals, small animals, and robert waldow. In a pyramid of people, the people on the bottom will be support the weight of everyone above. If they try to build the period to large, the people on the bottom will not be able to give the right amount of support and the pyramid would collapse. Build a tall mountain and the bottom would slide and slump.
