Creation and evolution in public education

The status of creation and evolution in public education has been the subject of substantial debate and conflict in legal, political, and religious circles. Globally, there is a wide variety of views on the topic; in some countries legislation forbids teachers to discuss either the evidence for evolution or the modern evolutionary synthesis, the explanatory scientific theory of evolution. In other countries legislation mandates that only evolutionary biology is to be taught in the appropriate scientific syllabuses.
