The Sum of its Parts: how the building blocks of a trait can change while the trait stays the same
“Such interconnected systems seem hardly capable of change: alter one part, and the whole thing could break. However, a system’s final product is often what matters for an organism’s ability to live and reproduce. As long as a system produces the more-or-less correct output, the individual parts of the system do not necessarily matter. This potentially allows for a surprising amount of evolution of the individual parts without changing the output of the system.”
