said that these features, present in populations all over the 

 world, connect the Australian Aboriginals with other popula- 

 tions(Rochlin 1965;Sandison 1973). Evidence of nutritional 

 and metabolic disorders were found in some bones and teeth, 

 such as fine pitting on the bone surface (Figure 2), enamel 

 hypoplasia in front teeth (Figure 8), and thickening of the 

 diploe of the frontal bone (Figure 9). 



GENETICS 



Inborn anomalies found in Roonka include supernumerary 

 cusps on molars, shovel-shaped incisors, tuberculum dentale 

 (Figure 10), protruding lower jaw (underbite), aplasia of lat- 

 eral incisors, and other features. These are also found in 

 every population in the world, sometimes perhaps with dif- 

 ferent frequencies. 



Crowded teeth in lower jaws were quite frequent (28%) in 

 the Roonka adult population (Figure 1 1 ). Heavy stress on the 

 teeth since childhood may be blamed for this, since pressure 

 acts in the direction from the molars toward the front teeth.
