explaining that:
"What is Life presents conceptual thinking in biology. While many current issues in biology are based on simple ideas, the elucidation of biological mechanisms that explain diverse aspects of life is challenging because cells and organisms are complex systems. To understand how biologists study the structure and function of living organisms one has to understand the relationship between experiment and theory. Such an understanding amounts to scientific literacy."
