SO ENDS this meander down floral structure. Taking quantified traits from a large number of floral species as well as their pollinators, and tracking them through evolutionary time has proved to be a powerful tool in understanding flowers. In this way, one can cover millions of years of evolution across species in a single snapshot. And as fitness is the sum of survival and reproductive success, a fitness landscape plot can be derived. This exemplar is being applied to other systems with interesting results.
