Biology is a fundamental area of human knowledge. It involves an understanding of the determinants of our appearance and behaviour, biological processes such as breathing and sleeping, as well the knowledge that substances which may look good to eat may not be so in reality. This chapter explores whether children understand that physical attributes such as eye colour have a biological origin whereas food preferences, for example, are culturally determined; whether they can understand the microscopic basis of contamination and the transmission of illness; and whether they can identify processes of food purification. It examines different answers from children in America, India, and elsewhere.

Keywords: human knowledge; biology; children's biological concepts; food purification; America; India
