The other side of the story: How evolution impacts the environment
The story of the peppered moths is a textbook evolutionary tale. As coal smoke darkened tree bark near England's cities during the Industrial Revolution, white-bodied peppered moths became conspicuous targets for predators and their numbers quickly d.....»»
Scientists propose novel method to estimate human-caused heat emission
Why are cities usually warmer than rural areas? Scientist have long known that cities retain heat more than rural areas, a phenomenon known as urban heat island (UHI), which is largely due to the impact of anthropogenic heating, or human-caused heati.....»»
