Which word describes the form of a dark pigment in organisms?

• panoramic
• manlanic
• peramic
• melanic

The  MCr1 mutation across a variety of species shows that

• evolution is by design.
• evolution of melanism is a repeatable process.
• new mutations of melanism comes from a common ancestor.
• evolution of melanism is random.
