Ernst Schäfer (1910-1992) byl německý zoolog, sběratel přírodnin a cestovatel známý zejména díky třem průkopnickým výpravám do Tibetu, území, kam se přírodovědci prakticky nedostali až do druhé poloviny 20. století. Třetí expedice z let 1938-39 je poněkud kontroverzní, neboť se stala součástí nacistické propagandy a její cíle nebyly čistě jen vědecké., Ernst Schäfer (1910–92) was a German zoologist, collector and explorer who is primarily known for his three pioneering expeditions to Tibet, which was virtually closed to science well into the second half of the 20th century. The third expedition, in 1938–39, was rather controversial as it became a part of Nazi propaganda and its goals were not purely scientific., and Jan Robovský, Jiří Hrubý.
his year, we celebrate two hundred years since the birth of Charles Darwin (1809-1882), one of the world's most creative and influential thinkers, and one hundred and fifty years since the publication of his 1859 book On the Origin of Species. Charles Darwin presented compelling evidence that all living species have evolved over millions of years from a few ancestors through the process he termed natural selection. In 1831, Darwin set out on a British scientific expedition around the world. In South America Darwin found fossils of extinct animals that were similar to modern living species. On the Galapagos Islands in the Pacific Ocean he noticed many variations among plants and animals of the same general type as those in South America. Darwin visited many places around the world collecting specimens to further his studies. and Stanislav Komárek.
