Brazil's Atlantic Forest is considered one such hotspot, containing roughly 20,000 plant species, 1,350 vertebrates, and millions of insects, about half of which occur nowhere else.[citation needed] The island of Madagascar and India are also particularly notable. Colombia is characterized by high biodiversity, with the highest rate of species by area unit worldwide and it has the largest number of endemics (species that are not found naturally anywhere else) of any country. About 10% of the species of the Earth can be found in Colombia, including over 1,900 species of bird, more than in Europe and North America combined, Colombia has 10% of the world’s mammals species, 14% of the amphibian species, and 18% of the bird species of the world. Madagascar dry deciduous forests and lowland rainforests possess a high ratio of endemism.[citation needed] Since the island separated from mainland Africa 66 million years ago, many species and ecosystems have evolved independently.[citation needed] Indonesia's 17,000 islands cover 735,355 square miles (1,904,560 km2) and contain 10% of the world's flowering plants, 12% of mammals, and 17% of reptiles, amphibians and birds—along with nearly 240 million people. Many regions of high biodiversity and/or endemism arise from specialized habitats which require unusual adaptations, for example, alpine environments in high mountains, or Northern European peat bogs.[citation needed]

Whitehead did not begin his career as a philosopher. In fact, he never had any formal training in philosophy beyond his undergraduate education. Early in his life he showed great interest in and respect for philosophy and metaphysics, but it is evident that he considered himself a rank amateur. In one letter to his friend and former student Bertrand Russell, after discussing whether science aimed to be explanatory or merely descriptive, he wrote: "This further question lands us in the ocean of metaphysic, onto which my profound ignorance of that science forbids me to enter." Ironically, in later life Whitehead would become one of the 20th century's foremost metaphysicians.

What is the relationship between Whitehead and Russell?
Answer: friend and former student

The 1977 Knesset elections marked a major turning point in Israeli political history as Menachem Begin's Likud party took control from the Labor Party. Later that year, Egyptian President Anwar El Sadat made a trip to Israel and spoke before the Knesset in what was the first recognition of Israel by an Arab head of state. In the two years that followed, Sadat and Begin signed the Camp David Accords (1978) and the Israel–Egypt Peace Treaty (1979). In return, Israel withdrew from the Sinai Peninsula, which Israel had captured during the Six-Day War in 1967, and agreed to enter negotiations over an autonomy for Palestinians in the West Bank and the Gaza Strip.

Israel withdrew from where?
Answer:
Sinai Peninsula
