Pa. In Search of the Tooth John Verano's photograph of the lateral view of a bashed-in skull shows the victim with only one right bicuspid, or premolar. Of course, their mean age at death was just 23. Its upper lateral incisors and third molars are smaller than normal, so I think it is a case of congenital absence of one premolar with similar, but less serious, effects on the other teeth. I have seen very few cases of congenitally absent premolars in my north-coast samples, but absence of one or more third molars is relatively common. I couldn't imagine a reptile having the strange and delicate skin required for suction pads.
Geckos are, in fact, reptiles.
Their feet have pads with microscopic backward-projecting hooks that cling even to the smallest surface irregularity. There were entrance and exit ramps about every half mile, but once out of the Loop, almost no traffic entered, and leaving was usually unencumbered. Trucks were prohibited, so spacing became very regular, and I'm sure the density was much greater than the 35 cars per mile per lane proposed in your article. Of course, if a major defect occurred, the pattern reverted to the usual chaos. Ed Henze Moran, Wyo.
