The official language, Lithuanian, along with Latvian, is one of only two living languages in the Baltic branch of the Indo-European language family.  - The Karisoke Research Center in Rwanda's Volcanoes National Park was founded by Dian Fossey on 24 September 1967, to study endangered mountain gorillas. Fossey located the camp in Rwanda's Virunga volcanic mountain range, between Mount Karisimbi and Mount Bisoke, and named it by combining the names of the two mountains.   - The mountain gorilla ("Gorilla beringei beringei") is one of the two subspecies of the eastern gorilla. There are two populations. One is found in the Virunga volcanic mountains of Central Africa, within three National Parks: Mgahinga, in south-west Uganda; Volcanoes, in north-west Rwanda; and Virunga in the eastern Democratic Republic of Congo (DRC). It is listed as critically endangered by the IUCN. The other is found in Uganda's Bwindi Impenetrable National Park. Some primatologists consider the Bwindi population in Uganda may be a separate subspecies, though no description has been finalized. As of September 2016, the estimated number of mountain gorillas remaining is about 880.  - The Trimates , sometimes called Leakey 's Angels , is a name given to three women -- Jane Goodall , Dian Fossey , and Birut Galdikas -- chosen by anthropologist Louis Leakey to study hominids in their natural environments . They studied chimpanzees , gorillas and orangutans respectively .  - Rwanda (or ), officially the Republic of Rwanda, is a sovereign state in central and east Africa and one of the smallest countries on the African mainland. Located a few degrees south of the Equator, Rwanda is bordered by Uganda, Tanzania, Burundi and the Democratic Republic of the Congo. Rwanda is in the African Great Lakes region and is highly elevated; its geography is dominated by mountains in the west and savanna to the east, with numerous lakes throughout the country. The climate is temperate to subtropical, with two rainy seasons and two dry seasons each year.  - Kenya, officially the Republic of Kenya, is a country in Africa and a founding member of the East African Community (EAC). Its capital and largest city is Nairobi. Kenya's territory lies on the equator and overlies the East African Rift covering a diverse and expansive terrain that extends roughly from Lake Victoria to Lake Turkana (formerly called Lake Rudolf) and further south-east to the Indian Ocean. It is bordered by Tanzania to the south and southwest, Uganda to the west, South Sudan to the north-west, Ethiopia to the north and Somalia to the north-east. Kenya covers , and had a population of approximately 45 million people in July 2014.  - An anthropologist is a person engaged in the practice of anthropology. Anthropology is the study of various aspects of humans within past and present societies. Social anthropology and cultural anthropology study the norms and values of societies. Linguistic anthropology studies how language affects social life. Biological or physical anthropology studies the biological development of humans.  - Dian Fossey (January 16, 1932  c. December 26, 1985) was an American zoologist, primatologist, and anthropologist who undertook an extensive study of mountain gorilla groups over a period of 18 years. She studied them daily in the mountain forests of Rwanda, initially encouraged to work there by anthropologist Louis Leakey. Her 1983 book, "Gorillas in the Mist", combines her scientific study of the gorillas at Karisoke Research Center with her own personal story. It was adapted into a 1988 film of the same name. Fossey was murdered in 1985; the case remains open.  - Louis Seymour Bazett Leakey (7 August 1903  1 October 1972), also known as L. S. B. Leakey, was a Kenyan paleoanthropologist and archaeologist whose work was important in demonstrating that humans evolved in Africa, particularly through discoveries made at Olduvai Gorge with his wife, fellow paleontologist Mary Leakey. Having established a program of palaeoanthropological inquiry in eastern Africa, he also motivated many future generations to continue this scholarly work. Several members of Leakey's family became prominent scholars themselves.  - Birut Marija Filomena Galdikas, OC (born 10 May 1946), is a Lithuanian anthropologist, primatologist, conservationist, ethologist, and author. She is currently a Professor at Simon Fraser University. Well known in the field of primatology, Galdikas is recognized as a leading authority on orangutans. Prior to her field study of orangutans, scientists knew little about the species.  - Gorillas in the Mist is a 1988 American drama film directed by Michael Apted and starring Sigourney Weaver as naturalist Dian Fossey. It tells the true story of her work in Rwanda with mountain gorillas and was nominated for five Academy Awards.  - Olduvai Gorge, or Oldupai Gorge, in Tanzania is one of the most important paleoanthropological sites in the world; it has proven invaluable in furthering understanding of early human evolution. A steep-sided ravine in the Great Rift Valley that stretches across East Africa, it is about long, and is located in the eastern Serengeti Plains in the Arusha Region not far, about , from Laetoli, another important archaeological site of early human occupation. The British/Tanzanian paleoanthropologist-archeologist team Mary and Louis Leakey established and developed the excavation and research programs at Olduvai Gorge which achieved great advances of human knowledge and world-renowned status.  - Mary Leakey (6 February 1913  9 December 1996) was a British paleoanthropologist who discovered the first fossilised "Proconsul" skull, an extinct ape which is now believed to be ancestral to humans. She also discovered the robust "Zinjanthropus" skull at Olduvai Gorge in Tanzania, eastern Africa. For much of her career she worked with her husband, Louis Leakey, at Olduvai Gorge, where they uncovered fossils of ancient hominines and the earliest hominins, as well as the stone tools produced by the latter group. Mary Leakey developed a system for classifying the stone tools found at Olduvai. She discovered the Laetoli footprints, and at the Laetoli site she discovered hominin fossils that were more than 3.75 million years old.   - Gombe Stream National Park is located in western Kigoma Region, Tanzania, 10 miles (20 km) north of Kigoma, the capital of Kigoma Region. Established in 1968, Gombe is the smallest national park in Tanzania, with only of forest running along the hills of the eastern shore of Lake Tanganyika. The terrain is distinguished by steep valleys, and the forest vegetation ranges from grassland to alpine bamboo to tropical rainforest. Accessible only by boat, the park is most famous as the location where Jane Goodall pioneered her behavioral research conducted on the chimpanzee populations. The Kasakela chimpanzee community, featured in several books and documentaries, lives in Gombe Stream National Park.  - Tanzania , officially the United Republic of Tanzania, is a country in Eastern Africa within the African Great Lakes region. Parts of the country are in Southern Africa. It is bordered by Kenya and Uganda to the north; Rwanda, Burundi, and the Democratic Republic of the Congo to the west; Zambia, Malawi, and Mozambique to the south; and by the Indian Ocean to the east. Mount Kilimanjaro, Africa's highest mountain, is in northeastern Tanzania.  - Dame Jane Morris Goodall (born Valerie Jane Morris-Goodall, 3 April 1934), formerly Baroness Jane van Lawick-Goodall, is a British primatologist, ethologist, anthropologist, and UN Messenger of Peace. Considered to be the world's foremost expert on chimpanzees, Goodall is best known for her 55-year study of social and family interactions of wild chimpanzees in Gombe Stream National Park, Tanzania. She is the founder of the Jane Goodall Institute and the Roots & Shoots program, and she has worked extensively on conservation and animal welfare issues. She has served on the board of the Nonhuman Rights Project since its founding in 1996.  - Simon Fraser University, commonly referred to as SFU, is a public research university in British Columbia, Canada with campuses in Burnaby, Surrey, and Vancouver.  - The Jane Goodall Institute (JGI) is a global wildlife and environment conservation organization headquartered in Vienna, Virginia.
