Animal Health & Behavior
From ANIMAL PEOPLE, March 1993:
Studying the relationship between brain evolution and the death of fetal cells, University of
Tennessee researcher Dr. Robert Williams has discovered that cat species seem to have an unusual capacity for
fast biological adaptation to suit their circumstances. All mammals seem to select adaptive capabilities through
the death of up to half of their neural brain cells just before birth, enabling the remainder to grow, but cats shed as
many as 80% of their fetal neurons––and this explains the key differences between domestic cat brains and those
of Spanish wildcats. Williams studied the brains of domestic cats and Spanish wildcats who had been euthanized
due to illness and/or injury.
