This news can fit into curricula in several ways, in several courses: Insects have already evolved in response to climate shifts due to global warming.
The Boston Globe has a series on global warming, and a recent article detailed how mosquitoes on the Maine frontier have already changed their breeding seasons in response to warming weather.
A mosquito that can barely fly is one of only five known species that scientists say have already evolved because of global warming. The unobtrusive mosquito’s story illustrates a sobering consequence of climate change: The species best suited to adapting may not be the ones people want to survive.
Such news enhances biology studies of genetics and insects, geography studies of climate, animal dispersal patterns and disease and pest ranges (a subject more technically known as biogeography), and the articles lend urgency to studies of how governments react to natural crises, a topic suitable for government classes, economics, and U.S. and world history.
