Evolution

Why could the same species of moth be two different colors?

• Their color was based on their DNA. Sometimes a mutation would cause the moth to be born with a different color.

• Their color was caused by the environment. The soot from the factories would fuse with the moth's skin.

• Bacteria inside the moth's stomach would sometimes give the moth stomach the ability of the moth to have "active camouflouge." This allowed the moths to change their color at will.
