Cancerous cells can divide so rapidly that they will often produce a glycocalyx that is different than the other cells in the body. This may result in allowing the cancer cells to bind to their healthy, neighboring cells. Cancer is unchecked growth of cells. Cancer is caused by mutations in genes accelerating the rate of cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death.
Answer: This modern-day researcher used some of the same theories that Darwin proposed. Like Darwin and his finches and tortoises, this scientist understood that the Galapagos cormorants inherited flightless wings. Darwin eventually discovered that his Galapagos finches likely evolved from other species of finches on the mainland. This evolution was similar to how the flightless Galapagos cormorants evolved from other species of cormorants.
