The entire conceptual edifice of modern science is a product of biology. Even the most basic and profound ideas of science—relativity, quantum theory, the theory of evolution by natural selection—are generated and necessarily limited by the particular capacities of our human biology. This implies that the content and scope of scientific knowledge is not open-ended.
