The nonsynonymous substitution rate (Ka), the synonymous substitution rate (Ks), and their ratio (Ka/Ks) are commonly used to aid in understanding the direction of evolution and its selective strength in a coding sequence (Li et al. [2009]).
Understanding the direction and magnitude of change in any ecosystem trait in response to any driver is enabled by appropriate benchmarks.
Understanding the direction your story takes is crucial.

Operational sex ratios however, are key factors in understanding the intensity and direction of sexual selection in a population.
A new direction for understanding the physical phenomena in strain engineering is established.
