Researchers also noted that resistant worms grew more slowly than non-resistant worms, 'probably because of a diversion of resources into the production of large quantities of a metal-binding metallothionein-like protein'. wikipedia.org Like the cadmium-resistant worms, mutant wingless beetles and eyeless fish are usually at a disadvantage compared to 'normal' ones. But on windswept islands, natural selection favours wingless beetles (not blown out to sea) and in underwater caves, it favours eyeless fish (in a dark cave, eyes are prone to injury and subsequent infection).

wikipedia.org 카드뮴에 저항하는 벌레처럼, 돌연변이체인 날개 없는 딱정벌레(wingless beetles), 눈이 없는 물고기(eyeless fish) 등은 대게 정상적인 개체에 비해 불리한 개체들이다. 그러나 자연선택은 바람이 심하게 부는 섬에서 날개 없는 딱정벌레를(바다로 날려가지 않음으로), 어두운 동굴의 물속에서는 눈이 없는 물고기를(어두운 동굴에서 눈은 상처받기 쉽고 감염이 일어나기 쉽다) 선택하였다.
