Were there ever sympatric Th. sirtalis with low resistance living in areas with highly toxic T. granulosa? This would be something to look into because they did find the opposite instance. However, why were there high resistant snakes residing in areas with low toxicity newts? Because the analogy has a pattern of increasing resistance followed by increased defense, there has to be a fall-off and starting over at some point. In these areas where there were high resistant predators and low defensive prey, it is possible the arms race was either just beginning or starting over because it had maxed out. Brodie & Brodie (1990) could further their research by testing how high the toxicity levels of the newt can go in order to see if an arms race was truly occurring because they felt that there is a possible advantage to increased
