Solution
The correct answer is "the trunks of white birch trees".
Here's the step by step reasoning:
-
J.W. Tutt's study was about the peppered moth, which is known for its two primary color forms: light and dark (or 'peppered').
-
The light-colored moths were more common in the early 19th century, but as the Industrial Revolution progressed, the dark-colored moths became more common. This is known as 'industrial melanism'.
-
Tutt proposed that the light-colored moths were more visible to predators on the trunks of white birch trees, which were their natural habitat.
-
When these trees were covered in soot due to industrial pollution, the dark-colored moths had a survival advantage because they were better camouflaged against the darkened trees.
-
Therefore, the light-colored moths were more visible to predators on the trunks of white birch trees, not on sooty or dead trees due to pollution.
