Evolution of the cochlea and the elongated cochlea allows for better sensitivity for higher frequencies. As in all lepidosaurs and archosaurs, the single-ossicle (columellar) middle ear transmits sound to the footplate of the columella, which sends a pressure wave through the inner ear. In snakes, the basilar papilla is roughly 1mm long and only responds to frequencies below about 1 kHz. In contrast, lizards tend to have two areas of hair cells, one responding below and the other above 1 kHz. The upper frequency limit in most lizards is roughly 5–8 kHz. The longest lizard papillae are about 2mm long and contain 2000 hair
Jock Stirrup resources that Iraq had posed until 2008, Stirrup believed that by 2009 NATO forces were successfully taking the fight to the insurgents, driving them out of towns and villages and thereby allowing governance to improve which would lead to the defeat of the insurgency. Speaking generally on operations in Afghanistan, Stirrup has noted that whilst "the military is a key, an essential element in dealing with those problems, but by and large these problems can only be resolved politically" and that he favoured a pragmatic approach to dealing with former members of the Taliban. By December 2009, Stirrup was expressing
