  Some biologists accept Wright's adaptive landscape idea, believing it is one
of most profound concepts in evolutionary dynamics. Some wouldn't, believing
that "the idea that there is such a quantity remains one of the most widely
held popular misconceptions about evolution." The two groups usually have very
limited communication with each other. Sometimes such isolation can be good,
because it protects budding ideas in a harsh environment. Thanks to the
theoretical and experimental progress during past few years, time may have
arrived to consider both sides seriously. Present letter is a small attempt to
bridge this gap.
