Nstllfl to part 01 a lecture on a similar topic. Okay, today I want to talk to you about a hypotheSis that explains where humans might have evolved and how they might have migrated around the wOOd. It 's an alternative hypotheSis to the replacement hypolhesis thai you read about earllE)(. it's called the multiregioflal hypothesis but I've also heard it relerred to as the continuity hypothesis. Now, according to the IiCillfllists who support this view , modem humans spread throughout Eurasia about a million years ago and regional populations retained some unique anatomlcalleaturas IOf hundredsol thousands 01 years, but they also eKchanged some Inherited traits with neighboring populations when they mated with them. And we call this eKchange 01 traits 98fI8 flow. So through th is gene flow, certain characteristics that we consider crucial to modem mankind were inherited, as. 101' eKample. an Increase In brain size with an accompanying change in the skull. And and lhis gena flow resulted in Ihe avolution 01 the ealty humans whose remains ara found fhroughout Europe and Asia as well as AfriCa . Now, scientists who support th is theory contend that the populations tha t migrated were linked by gene flow so that the featur" that all pooplo have In common spread throughout tho world. Tho rola· lively slight diff8fences among modem people would have been caused by hundreds 01 thousands of years 01 regional evolution. Bul actually, rese81Che rs who SUPfX>/1 the continuity hypothesis tend to locus on the genetic similarities among human populations wOOd·wlde, not the differences. We're rea lly amazingly similar as a species. And the lossils of archaic and modem humans in some regiol'lS do sug. gest a continuous evolution in regionallraits, like the cheekbone structure, for e:uunple, which Is further evidence that modem humans may have evolved over a broad area among multiple groups of human ancestors. Sy Summarize the major points in the reading and eKpla ln how the lecturer casts doubt on those points. According to \he replacement hypothesis, also called the Out 01 Al riCa hypothe sis, modem humans evolved from a common ancestor In Africa. As they migrated to ASia and Eurooe. and finally SPread throughout the world, they replaced the less evolved populations that they encountered. Proatlor this hypothesis comes from both genetic and paleontological research, The large number 01 genetic: traits thai human populations have in common are confirmed by DNA investigations in mitochondria struc· tures. tn addition, !he oldest fossils Identified as modem human remalns have been discovered In AfriCa . Nevertheless, the lecturer casts doubt on the replacement theory, offering Ihe continuity hypothesis as an alternative. Also known as the multi regiOnal hypothesis, the continuity hypolhesis proposes that advanced human populations migrated and mated with less advanced r egiOnal populations, introducing ne w traits Into lhese populations. Because the regional populations were not replaced, they reta i ned some of their unique characteristics. The exchange oIlralts, referred to as gene flow, accounts fOf the genetic similarity 01 modem human beings. The retention 01 regional genetic material eKplalns why some tra its. such as Cheel\bone structure. are limited to discrete populations, and casts doubt on the replacement hypothesis, The fact that modern human remalns are found in widespread sites also sup- pons the alternative hypothesis that the lecturer presents. )pynghled maken II S34 ANSWERS AND AUDIO SCRIPTS FOR ACTtVmES, QUIZZES, AND MODEL TeSTS () A ctivity 38, CD 3, TI'Kk 4. Now that you have read the explanation of population In the reading, Nsten to part of a lecture on a similar topic. Well. it is certainly true that Malthus has had an III IOOTlOUS Impact on the study of population, and in lact. many of h is predictions about limitations on population appeared to be true lor a time. but right now the major debate in economic population theory Is bet eon a group who believes that population growth has reached a critical mass and can no longer be controlled through tho events and kHces that Malthus predicted and, on the other side 01 the debate. a group thai views ~ control as part of a Ia1ger dem0- graphic transition. HlH'e's wnat I mean. Demographic transition is a model in which large populations lTIO\Ie from Stage 1, with \I'IH'Y nigh birth and death rates li ke Malthus predicted, to Stage 21n which the birth rates remain high but tho death rates begin to decli ne . mostty because of progress in IoocI produc- tion, sanitation methods, and medical treatment, all o llhese modem advances that oould not have been predicted when Matthus was deVeloping his theory. So, the population grows vety rapidly In Stage 2. Okay, in Stage 3. population continues to increase because, although the birth rate decreases. the death rate also decreases , so fewer people are born, but they tend to live longer. Now Stage 4 is the point al which the population Increases very sIowty, Of it may even start to decline because both the birth rate and death rates are even lower than in the previous stage . So we see this in Japan , Europe, and North Amerk:a. In tact. In Europe, we see something that appears to be a Stage 5. In Europe, the decline In the birth rate has dropped to a level 01 1.7. whIctlls below the 2.0 replaooment level lor a oou- pie. So, unless immigration rates inaease , Europe's population may be an Indication of Mure demo- graphies lor other industrialized regions. Summarize the major points In the lecture that you have jus t heard, explaining how they cast doubt on the Ideas In the reading passage. ADouditog to the lecturer, one modem view asserts that wend population has reached a "critical mass ." and the limiting Ioro&s Ma/thus had poqued to control population , such as war, SlalVBIion, disease , and disasters. can no longer stem the growth In contrast. another group 01 EICOI'IOI'rMsts argues lhat population control Is part 01 a live slE1Q8 demograptk transition model, From Stage 1, In IOIttilIarge bifIh rates and death rates interact someMlai like MaIthus prGdicted , populations move into Stage 2, characterized by Y8IY rapid gn:tow1h as all!SUltol' impio.ements in sanitation, agriculture , and medicine, By Stage 3, both the birth and death rates decrease, a trend that oontinues in Stage 4 u the population growth slows at even declines. At Stage 5. birth rates fall below repIaoement levels , and even with deciI WIg death rates, the population begins to deaease . The lecturer notes that the industriailed areas 01' Japan and Nof1tI Amer- Ica are in Stage 4, whereas Europe appears 10 be rnQ'\/Wlg from Stage 4 to Stage 5. Since Malthus pointed cui that populations at the highest level of the economy exerd$e oontroIs as a resull of education and a desire to preserve their standard of living. he did, in a way , predict the trends lor the Industrialized world : however , he certainly did not foresee advances In agricullure, public health , and medicine that would Inftl.l8oce population, According to the lecturer, his pred ic:tiolls are not valid lor the criIic:aI mass model and are 8COJrate ooIy lor the beginning staoes 01 the demographic: transition righted aler . and In !tat oo .
