Current science recognizes the fallacy in the theory of macro-evolution. You will not find it touted as fact in academic circles the way you do in public primary schools and even in the media.

Children’s Environmental Health Center (CEHC) at Mount Sinai School of Medicine developed the list of ten chemicals found in consumer products that are suspected to contribute to autism and learning disabilities to guide a research strategy to discover potentially preventable environmental causes. The top ten chemicals are:
8.Polycyclic aromatic hydrocarbons
9.Brominated flame retardants
