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
Stirrup jar been made, but are generally unsupported. The most common, wine, had its own battery of containers from serving and drinking ware (cups, mixers, bowls, etc.) to transport vessels, the amphorae, which are generally larger and more plentiful than stirrup-jars. Wine was apparently more plentiful. Oil requires a significant investment in olive trees, which cannot be harvested for several years after planting. A third suggestion, perfume, is not compatible with the small quantities placed in perfume jars, which are always very small. The relatively large stirrup jars would represent unrealistically huge amounts of perfume. The early stirrup-jars were not distinguished by
