The new seven-volume Discovering the Earth set examines the efforts made by scientists in the fields of environment, environmental protection, and environmental science. Covering a broad range of topics--including the Earth sciences, atmosphere, oceans, ecology, animals, plants, and exploration--the books in this comprehensive set provide a panorama of brief accounts of particular discoveries and the people who made them. These stories explain the problems that were solved, the ways they were approached, and, in some cases, the dead ends that scientists sometimes reached. Ideal for high school and college students and particularly valuable to students of environmental studies, ecology, biology, geography, geology, and the humanities, the books in the Discovering the Earth set shed light on the way the scientific aspect of Western culture has developed. Written in clear language and requiring no mathematical knowledge, these helpful books feature sidebars where necessary to explain a particular concept as well as full-color photographs, tables, charts, and further resources.

followed by several more generations, each generation consisting only of females. Sometimes aphids produce a generation of females with wings that migrate to another Generation, Species, and Evolution plant nearby, where they start a new colony. The final generation of the season, produced parthenogenetically like its predecessors, comprises males as well as females, and both genders possess wings. They mate, the females lay eggs, and then the insects die. An individual aphid lives for three to

The couple had four sons and one daughter, but the daughter and one of the sons died in infancy. Another son, Robert Waring Darwin (–), was Charles Darwin’s father. Mary died in , but Darwin continued to live in the same house with his housekeeper and Robert’s governess, Mary Parker, with whom he had two daughters. He married a widow, Elizabeth Pole, in , and moved into her

This discovery was made by Gregor Mendel, who was a monk in the Augustinian monastery of St. Thomas in what was then the town of Brünn, in Moravia, a part of Austria; the town is now Brno, in the Czech Republic. Mendel was born on July , , on a farm at Heizendorf, Silesia, then part of Austria; it is now Hynčice, Czech Republic. He was given the

him that all sexually reproducing organisms possess a substance called germ plasm containing the hereditary material that passes to the eggs or sperm cells. Offspring inherit the hereditary material from their parents’ germ plasm, and this directs the development of the cells of the body. The germ plasm passes from one generation to the next in an unbroken line of descent, and it flows in only one direction, from the eggs and sperm cells to the body cells, and never from the body cells to the

He held this position until , when he took up an appointment as professor of zoology at the University of Oxford, where he established a school of animal behavior. Tinbergen remained at Oxford until he retired in . He became a British citizen in . In addition to his academic work, Niko Tinbergen wrote books about wildlife for children and made many natural history films. In the years following his retirement, Tinbergen and his wife
