Divide and rule
Divide and rule Scientists say that the evolutionary success of
plants may be due to an accidental gene duplication. The duplicated

plant cells. The duplication allows for diversity and
specialization in the function of the cells. Specialization of
function is an important step in evolution. 29 AUGUST 1998, P. 13
