n Activity 37, CD 3, Track 3, Now that you have read the explanation 01 human migration pat· terns In the reading 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 this 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 this theory contend that the populations that 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, rese81Chers who SUPfX>/1 the continuity hypothesis tend to

locus on the genetic similarities among human populations wOOd·wlde, not the differences We're really

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 eKplaln how the lecturer casts doubt on those points

According to \he replacement hypothesis, also called the Out 01 AlriCa hypothesis, 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 regiOnal populations, introducing

new traits Into lhese populations Because the regional populations were not replaced, they retained 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 traits 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

( ) Activity 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 his 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 like Malthus predicted, to Stage 21n which the

birth rates remain high but tho death rates begin to decline mostty because of progress in IoocI

produc-tion, sanitation methods, and medical treatment, all ollhese 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 just 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, is predic:tiolls are not valid lor

the criIic:aI mass model and are 8COJrate ooIy lor the beginning staoes 01 the demographic: transition
