CLAIM: The increase of dark moths in England is caused by industrial pollution.
EVIDENCE: In the 19th century, before the industrial revolution, the majority of moths in England were light-colored. However, after the industrial revolution, the number of dark-colored moths increased significantly. Studies have shown that the dark coloration in moths is due to a genetic mutation, and that this mutation is more prevalent in areas with high levels of pollution.
REASONING: The evidence suggests that industrial pollution is the cause of the increase in dark moths in England. The mutation that causes dark coloration is more common in polluted areas, indicating that pollution is a key factor in the increase of dark moths. The correlation between industrialization and the increase of dark moths further supports this reasoning.
