evolution human thought food diet

  • Our earliest ancestors ate their food raw — fruit, leaves, maybe some nuts. When they ventured down onto land, they added things like underground tubers, roots and berries.
  • "You can't have a large brain and big guts at the same time," explains Leslie Aiello, an anthropologist and director of the Wenner-Gren Foundation in New York City, which funds research on evolution. Digestion, she says, was the energy-hog of our primate ancestor's body. The brain was the poor stepsister who got the leftovers.
  • "What we think is that this dietary change around 2.3 million years ago was one of the major significant factors in the evolution of our own species," Aiello says.

  • that could have been made only by a sharp tool.
  • But Aiello's favorite clue is somewhat ickier — it's a tapeworm. "The closest relative of human tapeworms are tapeworms that affect African hyenas and wild dogs," she says.
  • Besides better taste, cooked food had other benefits — cooking killed some pathogens on food.
  • It breaks up the long protein chains, and that makes them easier for stomach enzymes to digest. "
  • collagen is very hard to digest. But if you heat it, it turns to jelly."
  • starchy foods like turnips, cooking gelatinizes the tough starch granules and makes them easier to digest too. Even just softening food — which cooking does — makes it more digestible. In the end, you get more energy out of the food.

Indonesia Minangkabau effects environment environmental problems

  • Minangkabau
  • The Minangkabau--who predominate along the coasts of Sumatera Utara and Sumatera Barat, interior Riau, and northern Bengkulu provinces--in the early 1990s numbered more than 3.5 million. Like the Batak, they have large corporate descent groups, but unlike the Batak, the Minangkabau traditionally reckon descent matrilineally. In this system, a child is regarded as descended from his mother, not his father. A young boy, for instance, has his primary responsibility to his mother's and sisters' clans. In practice, in most villages a young man will visit his wife in the evenings but spend the days with his sister and her children. It is usual for married sisters to remain in their parental home. According to a 1980 study by anthropologist Joel S. Kahn, there is a general pattern of residence among the Minangkabau in which sisters and unmarried lineage members try to live close to one another, or even in the same house.
  • Indonesia, a vast polyglot nation, has made significant economic advances under the administration of President YUDHOYONO but faces challenges stemming from the global financial crisis and world economic downturn. Indonesia's debt-to-GDP ratio in recent years has declined steadily because of increasingly robust GDP growth and sound fiscal stewardship. The government has introduced significant reforms in the financial sector, including in the areas of tax and customs, the use of Treasury bills, and capital market supervision. Indonesia's investment law, passed in March 2007, seeks to address some of the concerns of foreign and domestic investors. Indonesia still struggles with poverty and unemployment, inadequate infrastructure, corruption, a complex regulatory environment, and unequal resource distribution among regions. The non-bank financial sector, including pension funds and insurance, remains weak. Despite efforts to broaden and deepen capital markets, they remain underdeveloped. Economic difficulties in early 2008 centered on high global food and oil prices and their impact on Indonesia's poor and on the budget. The onset of the global financial crisis dampened inflationary pressures, but increased risk aversion for emerging market assets resulted in large losses in the stock market, significant depreciation of the rupiah, and a difficult environment for bond issuance. As global demand has slowed and prices for Indonesia's commodity exports have fallen, Indonesia faces the prospect of growth significantly below the 6-plus percent recorded in 2007 and 2008.

  • Landholding is one of the crucial functions of the female lineage unit called suku. Since the Minangkabau men, like the Acehnese men, often merantau (go abroad) to seek experience, wealth, and commercial success, the women's kin group is responsible for maintaining the continuity of the family and the distribution and cultivation of the land. These groups are led by a penghulu (headman). The leaders are elected by groups of lineage leaders. As the suku declines in importance relative to the outwardly directed male sphere of commerce, however, the position of penghulu is not always filled after the death of the incumbent, particularly if lineage members are not willing to bear the expense of the ceremony required to install a new penghulu.

  • Indonesia has a stated foreign policy objective of establishing stable fixed land and maritime boundaries with all of its neighbors; Timor-Leste-Indonesia Boundary Committee has resolved all but a small portion of the land boundary, but discussions on maritime boundaries are stalemated over sovereignty of the uninhabited coral island of Pulau Batek/Fatu Sinai in the north and alignment with Australian claims in the south; many refugees from Timor-Leste who left in 2003 still reside in Indonesia and refuse repatriation; a 1997 treaty between Indonesia and Australia settled some parts of their maritime boundary but outstanding issues remain; ICJ's award of Sipadan and Ligitan islands to Malaysia in 2002 left the sovereignty of Unarang rock and the maritime boundary in the Ambalat oil block in the Celebes Sea in dispute; the ICJ decision has prompted Indonesia to assert claims to and to establish a presence on its smaller outer islands; Indonesia and Singapore continue to work on finalization of their 1973 maritime boundary agreement by defining unresolved areas north of Indonesia's Batam Island; Indonesian secessionists, squatters, and illegal migrants create repatriation problems for Papua New Guinea; piracy remains a problem in the Malacca Strait; maritime delimitation talks continue with Palau; Indonesian groups challenge Australia's claim to Ashmore Reef; Australia has closed parts of the Ashmore and Cartier Reserve to Indonesian traditional fishing and placed restrictions on certain catches
