Scholars agree that they were f
11、irst domesticated from a wild form called red junglefowl (Gallus gallus), a bird that still runs wild in most of southeast Asia, most likely hybridized with the gray junglefowl (G. sonneratii). That occurred probably about 8,000 years ago. Recent research suggests, however, there may have been multi
12、ple other domestication events in distinct areas of South and Southeast Asia, southern China, Thailand, Burma, and India. Since the wild progenitor of chickens is still living, several studies have been able to examine the behaviors of wild and domestic animals. Domesticated chickens are less active
13、, have fewer social interactions with other chickens, are less aggressive to would-be predators, are less susceptible to stress, and are less likely to go looking for foreign food sources than their wild counterparts. Domestic chickens have increased adult body weight and simplified plumage; domesti

David Wilmot The earliest possible domestic chicken remains are from the Cishan site (5400 BCE) in northern China, but whether they are
15、 domesticated is controversial. Firm evidence of domesticated chickens isnt found in China until 3600 BCE. Domesticated chickens appear at Mohenjo-Daro in the Indus Valley by about 2000 BCE and from there the chicken spread into Europe and Africa. Chickens arrived in the Middle East starting with Ir
16、an at 3900 BCE, followed by Turkey and Syria (24002000 BCE) and into Jordan by 1200 BCE. The earliest firm evidence for chickens in east Africa are illustrations from several sites in New Kingdom Egypt (15501069). Chickens were introduced into western Africa multiple times, arriving at Iron Age site
17、s such as Jenne-Jeno in Mali, Kirikongo in Burkina Faso and Daboya in Ghana by the mid-first millennium CE. Chickens arrived in the southern Levant about 2500 BCE and in Iberia about 2000 BCE. Chickens were brought to the Polynesian islands from Southeast Asia by Pacific Ocean sailors during the Lap
18、ita expansion, about 3,300 years ago. While it was long assumed that chickens had been brought to the Americas by the Spanish conquistadors, presumably pre-Columbian chickens have been identified at several sites throughout the Americas, most notably at the site of El Arenal-1 in Chile, ca 1350 CE.
19、Chicken Origins: China? Two long-standing debates in chicken history still remain at least partially unresolved. The first is the possible early presence of domesticated chickens in China, prior to dates from southeast Asia; the second is whether or not there are pre-Columbian chickens in the Americ
20、as. Genetic studies in the early 21st century first hinted at multiple origins of domestication. The earliest archaeological evidence to date is from China about 5400 BCE, in geographically widespread sites such as Cishan (Hebei province, ca 5300 BCE), Beixin (Shandong province, ca 5000 BCE), and Xi
21、an (Shaanxi province, ca 4300 BCE). In 2014, a few studies were published supporting the identification of early chicken domestication in northern and central China (Xiang et al.). However, their results remain controversial. A 2016 study by Chinese bioanthropologist Masaki Eda and colleagues of 280
22、 bird bones reported as chicken from Neolithic and Bronze age sites in northern and central China found that only a handful could securely be identified as chicken. German archaeologist Joris Peters and colleagues (2016) looked at environmental proxies in addition to other research and concluded tha
23、t the habitats conducive to jungle fowl were simply not present early enough in China to allow for the domestication practice to have taken place. These researchers suggest that chickens were a rare occurrence in northern and Central China, and thus probably an import from southern China or Southeas
24、t Asia where evidence of domestication is stronger. Based on those findings, and despite the fact that southeast Asian progenitor sites have not as yet been identified, a northern Chinese domestication event separate from that of southern China and Southeast Asia does not at present seem likely. Pre
25、-Columbian Chickens in America In 2007, American archaeologist Alice Storey and colleagues identified chicken bones at the site of El-Arenal 1 on Chiles coast, in a context dated well before the 16th-century medieval Spanish colonization, ca. 1321 1407 cal CE. The discovery is considered evidence of
26、 pre-Columbian contact of South America by Polynesian sailors, but that is still a somewhat controversial notion in American archaeology. However, DNA studies have provided genetic support, in that chicken bones from el-Arenal contain a haplogroup which has been identified at Easter Island, which wa
27、s founded by Polynesians around 1200 CE. The founding mitochondrial DNA cluster identified as Polynesian chickens includes A, B, E, and D. Tracing sub-haplogroups, Portuguese geneticist Agusto Luzuriaga-Neira and colleagues identified sub-haplotype E1a(b) which is found in both Easter Island and el-
28、Arenal chickens, a key piece of genetic evidence supporting the pre-Columbian presence of Polynesian chickens on the coast of South America. Additional evidence suggesting pre-Columbian contact between South Americans and Polynesians has also been identified, in the form of ancient and modern DNA of
29、 human skeletons in both locations. Currently, it seems likely that the chickens at el-Arenal were likely brought there by Polynesian sailors. 题目回忆 暂缺 参考阅读 C8T4P3.

40、e 3 题目 博弈 话题分类 语言文化类 题型及对应数量 暂缺 内容回忆 Game theory in the form known to economists, social scientists, and biologists, was given its first general mathematical formulation by John von Neuman and Oskar Morgenstern (1944). For reasons to be discussed later, limitations in their formal framework initiall
41、y made the theory applicable only under special and limited conditions. This situation has dramatically changed, in ways we will examine as we go along, over the past seven decades, as the framework has been deepened and generalized. Refinements are still being made, and we will review a few outstan
42、ding problems that lie along the advancing front edge of these developments towards the end of the article. However, since at least the late 1970s it has been possible to say with confidence that game theory is the most important and useful tool in the analysts kit whenever she confronts situations
43、in which what counts as one agents best action (for her) depends on expectations about what one or more other agents will do, and what counts as their best actions (for them) similarly depend on expectations about her. Despite the fact that game theory has been rendered mathematically and logically
44、systematic only since 1944, game-theoretic insights can be found among commentators going back to ancient times. For example, in two of Platos texts, the Laches and the Symposium, Socrates recalls an episode from the Battle of Delium that some commentators have interpreted (probably anachronisticall
45、y) as involving the following situation. Consider a soldier at the front, waiting with his comrades to repulse an enemy attack. It may occur to him that if the defense is likely to be successful, then it isnt very probable that his own personal contribution will be essential. But if he stays, he run
46、s the risk of being killed or wounded apparently for no point. On the other hand, if the enemy is going to win the battle, then his chances of death or injury are higher still, and now quite clearly to no point, since the line will be overwhelmed anyway. Based on this reasoning, it would appear that
47、 the soldier is better off running away regardless of who is going to win the battle. Of course, if all of the soldiers reason this wayas they all apparently should, since theyre all in identical situationsthen this will certainly bring about the outcome in which the battle is lost. Of course, this
48、point, since it has occurred to us as analysts, can occur to the soldiers too. Does this give them a reason for staying at their posts? Just the contrary: the greater the soldiers fear that the battle will be lost, the greater their incentive to get themselves out of harms way. And the greater the s
49、oldiers belief that the battle will be won, without the need of any particular individuals contributions, the less reason they have to stay and fight. If each soldier anticipates this sort of reasoning on the part of the others, all will quickly reason themselves into a panic, and their horrified commander will have a rout on his hands before the enemy has even engaged. 题目回忆
