Sentence examples for several evolutionary forces from inspiring English sources

Several evolutionary forces may, however, interact at the same time.

This fact does not ensure the maintenance of their global functional role (Friedberg et al., 2001) because the property of global regulation depends on several evolutionary forces and on TF's particular molecular properties (Lozada-Chavez et al., 2008).

In this review, we present several key points in modern research on the role of evolutionary forces in affecting mitochondrial genomes in Metazoa.

Although these studies have shed some light on the evolutionary forces acting on TFBS and other regulatory elements, several issues remain poorly explored or even unexplored.
