Step-by-step explanation:
One scientist who has studied biodiversity and believes that extreme environments may provide insight into life on other planets is Dr. Robert Ballard. He is an oceanographer and explorer who is best known for his discovery of the wreck of the Titanic in 1985.
Dr. Ballard has also conducted many deep-sea explorations, including the discovery of hydrothermal vents on the ocean floor that support unique ecosystems. He has suggested that these extreme environments may provide clues about the types of life that could exist on other planets, particularly those that are hostile to human life.
