Scientists believe that the Hawaiian island chain as it currently exists was formed as sea-floor spreading caused the Earth's crust to slowly move over a stationary point of volcanic activity in the mantle of the Earth.
While above the area of activity, volcanic eruptions formed the islands, and as sea-floor spreading moved the newly formed island off the area of activity, other new islands formed leading to the seven islands that now exist. The largest island in the chain is the only one that is currently volcanically active, suggesting that it is still above the active region on the mantel.

A continental population of insects has blue, red, green, and black variations. The color is controlled by the interaction of two genes, one with two alleles, the other with three alleles.
A piece of driftwood carrying two green insects and five red insects floats in the ocean for several days and washes up on a small island where the insect species did not previously live. The seven insects establish a new population on the island that increases in number significantly over several generations.

Cheetah populations in Africa have been increasing for the past several decades from numbers in the hundreds to numbers in the thousands.
A study was conducted in which skin tissue samples were obtained from five wild cheetahs and grafted onto five other cheetahs. An immune response regarding non-self tissue rejection was absent in the cheetahs that received the skin grafts.
Recently, a small wild population of cheetahs has become infected with a new type of infectious cancer. Scientists are concerned about the extinction of the entire species because
