The rapid growth of the human brain, or encephalization, in the last two million years or so has added to women's birth trauma.

A standard formula for assessing an animal's brain size compared to what would be expected from its body size is known as the encephalization quotient.
23.
"Homo ergaster " specimens indicate a change toward a diet more reliant on animal products, evident by greater encephalization with higher energy requirements.
24.
The reason for this encephalization is difficult to discern, as the major changes from Homo erectus to Homo heidelbergensis were not associated with major changes in technology.
25.
Biologist Stephen Jay Gould has noted that if one looks at vertebrates with very low encephalization quotients, their brains are slightly less massive than their spinal cords.
26.
In an attempt to use cranial capacity as an objective indicator of brain size, the encephalization quotient ( EQ ) was developed in 1973 by Harry Jerison.
27.
The encephalization quotient ( EQ ) ( the size of the brain relative to body size ) of elephants ranges from 1.13 to 2.36.

The encephalization quotient of some cetaceans is therefore higher than that of most primates, including the nearest relatives of humans, such as " Australopithecus ".
30.
A formula called the encephalization quotient ( EC ) expresses a relationship between brain and body size; it was developed by H . J . Jerison in the late 1960s.
