10、思阅读真题回忆：Passage 1题目鸡的历史话题分类生物科学类题型及对应数量暂缺内容回忆The history of chickens (Gallus domestics) is still a bit of a puzzle. Scholars agree that they were first domesticated from a wild form called red junglefowl (Gallus gallus), a bird that still runs wild in most of southeast Asia, most likely hybridized w

11、ith the gray junglefowl (G. sonneratii). That occurred probably about 8,000 years ago. Recent research suggests, however, there may have been multiple other domestication events in distinct areas of South and Southeast Asia, southern China, Thailand, Burma, and India.Since the wild progenitor of chi

12、ckens is still living, several studies have been able to examine the behaviors of wild and domestic animals. Domesticated chickens are less active, 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

13、 looking for foreign food sources than their wildcounterparts. Domestic chickens have increased adult body weight and simplified plumage; domestic chicken egg production starts earlier, is more frequent, and produces larger eggs.Chicken DispersalsChickens, Chang Mai, ThailandChickens, Chang Mai, Tha

14、iland. David WilmotThe earliest possible domestic chicken remains are from the Cishan site (5400 BCE) in northern China, but whether they are domesticated is controversial. Firm evidence of domesticated chickens isnt found in China until 3600 BCE. Domesticated chickens appear at Mohenjo-Daro in the

15、Indus Valley by about 2000 BCE and from there the chicken spread into Europe and Africa. Chickens arrived in the Middle East starting with Iran 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 illustration

16、s from several sites in New Kingdom Egypt (15501069). Chickens were introduced into western Africa multiple times, arriving at Iron Age sites 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 B

17、CE and in Iberia about 2000 BCE.Chickens were brought to the Polynesian islands from Southeast Asia by Pacific Ocean sailors during the Lapita 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-Colum

18、bian chickens have been identified at several sites throughout the Americas, most notably at the site of El Arenal-1 in Chile, ca 1350 CE.Chicken Origins: China?Two long-standing debates in chicken history still remain at least partially unresolved. The first is the possible early presence of domest

19、icated chickens in China, prior to dates from southeast Asia; the second is whether or not there are pre-Columbian chickens in the Americas.Genetic studies in the early 21st century first hinted at multiple origins of domestication. The earliest archaeological evidence to date is from China about 54

20、00 BCE, in geographically widespread sites such as Cishan (Hebei province, ca 5300 BCE), Beixin (Shandong province, ca 5000 BCE), and Xian (Shaanxi province, ca 4300 BCE). In 2014, a few studies were published supporting the identification of early chicken domestication in northern and central China

21、 (Xiang et al.). However, their results remain controversial.A 2016 study by Chinese bioanthropologist Masaki Eda and colleagues of 280 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.

22、German archaeologist Joris Peters and colleagues (2016) looked at environmental proxies in addition to other research and concluded that 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

23、suggest that chickens were a rare occurrence in northern and Central China, and thus probably an import from southern China or Southeast 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 identifie

24、d, a northern Chinese domestication event separate from that of southern China and Southeast Asia does not at present seem likely.Pre-Columbian Chickens in AmericaIn 2007, American archaeologist Alice Storey and colleagues identified chicken bones at the site of El-Arenal 1 on Chiles coast, in a con

25、text dated well before the 16th-century medieval Spanish colonization, ca. 13211407 cal CE. The discovery is considered evidence of pre-Columbian contact of South America by Polynesian sailors, but that is still a somewhat controversial notion in American archaeology.However, DNA studies have provid

26、ed genetic support, in that chicken bones from el-Arenal contain a haplogroup which has been identified at Easter Island, which was founded by Polynesians around 1200 CE. The founding mitochondrial DNA cluster identified as Polynesian chickens includes A, B, E, and D. Tracing sub-haplogroups, Portug

27、uese geneticist Agusto Luzuriaga-Neira and colleagues identified sub-haplotype E1a(b) which is found in both Easter Island and el-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

28、 pre-Columbian contact between South Americans and Polynesians has also been identified, in the form of ancient and modern DNA of 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.Passage 2题目运

40、enstern (1944).For reasons to be discussed later, limitations in their formal framework initially 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 b

41、een deepened and generalized. Refinements are still being made, and we will review a few outstanding 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 the

42、ory is the most important and useful tool in the analysts kit whenever she confronts situations 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 expectati

43、ons about her.Despite the fact that game theory has been rendered mathematically and logically 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 episo

44、de from the Battle of Delium that some commentators have interpreted (probably anachronistically) 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 i

45、snt very probable that his own personal contribution will be essential. But if he stays, he runs the risk of being killed or woundedapparently 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 p

46、oint, since the line will be overwhelmed anyway. Based on this reasoning, it would appear that 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 situations

47、then this will certainly bring about the outcome in which the battle is lost. Of course, this 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 soldiers belief that the battle will be won, without the need of any particular individuals contributions, the less rea
