Natural Selection

• Is a slight difference in an inherited trait of individual members of a species.

• The breeding of organisms for desired characteristics.

• Is an inherited trait that increases the organism’s chance of surviving and reproducing in its environment.

• The process where organisms that are best suited to their environment survive and pass on their genetic traits.

Before the industrial revolution, biologists in England observed that most peppered moths were light in color. After the industrial revolution began, most of the peppered moths observed were dark in color. Which statement best explains the observed change in moth color during the industrial revolution?

• Light-color moths were more fit for survival because they were less camouflaged against the darkened, soot-covered tree bark
• Dark-color moths were more fit for survival because they were less camouflaged against the darkened, soot-covered tree bark.
• Light-color moths were more fit for survival because they were more camouflaged against the darkened, soot-covered tree bark.
• Dark-color moths were more fit for survival because they were more camouflaged against the darkened, soot-covered tree bark.
