Then, as I first asked in chapter , where do such correlated fitness landscapes come from?

The error threshold is also controlled by the fitness landscape for the molecules.

In later chapters I will discuss the concept of a "fitness landscape."

But the problem is very much more complex than merely searching a fixed fitness landscape.

But so too is the fitness landscape of the fly, what it should do next.

It is not true for all fitness landscapes.

A fitness landscape with many local peaks surrounded by deep valleys is called rugged.

If all genotypes have the same replication rate, on the other hand, a fitness landscape is said to be flat.

Therefore it has a certain "ambition" to avoid local peaks in the fitness landscape.

Increasing "K" thus increases the ruggedness of the fitness landscape.
