This edition of "Biology : levels of life" has been produced to include all of the minor changes to the biology curriculum statement that took effect from the start of 2002. Many of the changes to the content of the course were already covered in the original edition of "Biology : levels of life". Page numbers have been conserved to ensure ease of use for classes with both editions"
