Discover the fascinating story of natural selection with our Pepper Moths and Industrial Revolution Organic Cotton T-Shirt. This unique design features an illustration of peppered moths, capturing their dramatic evolutionary shift during the Industrial Revolution. Before industrialization, the lighter-colored moths blended seamlessly with the lichen-covered tree bark, offering them camouflage from predators. However, as industrial pollution darkened the trees with soot, the darker-colored moths, which had previously been less common, became better camouflaged and thus had a survival advantage.

The shirt vividly depicts this shift in moth populations, demonstrating how environmental changes directly impacted survival and evolution. Lighter-colored moths became increasingly visible against the darkened backdrop and were more likely to be predated upon, while darker moths thrived and increased in number. This example of rapid evolutionary change highlights the powerful influence of environmental factors on natural selection.
