Moth collectors in England noted that most peppered moths collected in the early 1800’s were light gray peppered with bits of black. Many years later, most of the moths collected were almost completely black. What do the studies of changes between black and light color wings in populations of the peppered moth show?
changes in the environment can cause natural selection to act quickly
they were collecting a different species
natural selection doesn't work this quickly
work thise quickly
predators were only eating the black moths
