+The phenomenon of pervasive selection is generally most prevalent in pathogen evolution and any biological system influenced by evolutionary arms race dynamics
+(or balancing selection), including adaptive immune escape by viruses.
+MEME is ideally suited to identify sites under positive selection which
 represent candidate sites subject to strong selective pressures across the entire phylogeny or only on parts of the phylogeny.
 
-MEME is the sole method in HyPhy for detecting selection at individual sites that considers both pervasive and episodic selection. 
-MEME is therefore our recommended method if maximum power is desired.
