Answer & explanation:
Melanism occurs due to a genetic mutation that causes the excessive and concentrated production of the black pigment, called <u>melanin</u>. The consequence is living beings with darkened skin or fur. There are three types of melanism.
Adaptive melanism occurs by the need to adapt to the environment, a condition that will be passed through the generations. This melanism allows animals to camouflage themselves during hunting or to hide from predators.
Industrial melanism is related to human interference, especially industrial activities, in the lives of animals (dark-colored moths are the best-known cases). Air contamination is one of the main factors for this condition.
There is also pseudo-melanism, which partially affects animals and is generally motivated by genetic mutations. In certain species, the characteristic spots and stripes appear larger and darker than usual. This type of melanism is very present in cats such as tigers, cheetahs, leopards. However, other animals can still be affected.

Answer:
The main difference is motility and composition.
Explanation:
Cilia are structures involved in movement and therefore there's a strong nervous connection with the inside of the cell. Otherwise, microvilli are mainly used to increase absorption and they're also thinner and shorter.
Another great difference is the composition. Cilia are made up of microtubules, while microvilli is made up of microfilaments.
Answer: Multiple types of evidence support the theory of evolution: Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features).
