main et al 2011 pearson 2008 39 other problems of quantifying such long chronological morphological differences include the lack of various populations of modern australian aboriginals for example and certain prehistoric peoples being outside of the 95 confidence to fit the given morphological concept of amh clearly there needs to be a control on the temporal geographic population of the amh under consideration in such studies when carrying out both the statistical analysis with other fossil hominins and when taking the defining measurements pettitt 2005 132 137 argues that h sapiens should be classed into three arbitrary chronological groups of morphological continuity 1 those of the earliest h sapiens including material from bodo ethopia broken hill zambia and elandfontein south africa amongst others 2 transitional or archaic h sapiens including herto omo kibish 1 and 2 ethiopia florisbad south africa and jebel irhoud morocco 3 finally amh including makapansgat border cave and equus cave south africa taramsa egypt and dar es soltan morocco examples see table 2 below for dates this ordering of morphological continuity defines amh through the evolution of h sapien traits with retention of h ergaster traits earliest whilst the amh group compromise clear amh dating to less than 125 000 ya pettitt 2005 132 as pearson 2008 44 suggests the process of becoming modern likely occurred as a series of steps regardless of whether one considers these different steps to be different taxa in a bushy phylogeny or merely different grades in a single evolving lineage pearson 2008 44 goes on to say that the evolution of modern man should be viewed as a process rather than an event involving rapid morphological change due to drift during population bottlenecks and selection for new advantageous traits or genes or a combination of the two rather than a singular smooth process therefore we should be wary of relying purely on the often sparse fossil record regardless it is widely recognised that h sapiens are a probably daughter species of h erectus i e as a result of a speciation occurrence which spread across africa and into western eurasia at the beginning of or just before the middle pleistocene jurmain et al 2011 rightmire 2008 8 recent research has also led to five majority agreements in regards to the tenets of amh behaviour table 2 nowell 2010 447 wood 2005 109 makes the salient point that early eurocentrism in the search for amh behavioural origins clouded certain judgements such as focusing on western europe to the detriment of african archaeological sites points of consensus on modern behaviour the relationship between modern anatomy and modern behaviour is more complex than once thought modern behaviour has symbolic thoughts at its core archaeological record of the african middle stone age has rendered invalid the idea of a human revolution occurring for the first time in the upper palaeolithic of western europe later neandertal sites have demonstrated modern behaviour to either some form or some degree such as personal adornment or symbolic behaviour the triad of social cultural and demographic factors are key in understanding variability and patterning in the archaeology record table 2 agreed points in visioning the concept of modern behaviour balter 2011 21 nowell 2010 447 pettitt 2005 zilhao 2006 2010 1025 research jurmain et al 2011 prat et al 2012 has also highlighted symbolic behaviour in a number of early h sapiens sites throughout africa and the near east balter 2011 21 highlights aterian sites in north africa where various personal and possible symbolic artefacts have been found whilst blombos cave in south africa 77 000 ya and katanda in the dr of congo 80 000 ya have some of the earliest symbolic artefacts recovered including incised ochre worked bone and beads almost a full 45 000 years before any such artefacts appear in the european record jurmain et al 2011 298 299 mellars 2006 9383 proposes a model that indicates climatic environmental and cultural changes around 80 000 to 60 000 ya as major causative agents of cognitive change alongside population pressures in the dispersal of african h sapiens however nowell 2010 441 states that the gradual emergence of behaviours as a mosaic of features and not as a single revolutionary package should be considered within the archaeological record whilst defining that for the majority of researcher s symbolic language and codified social relationships define modern behaviour mosaic features in fossil hominids have been noted in recent discoveries of the australopithecus sediba specimen highlighting a mix of australopithecus and homo anatomical features wong 2012 25 the origins of amh living outside of africa have led to the formation of two major competing models in palaeoanthropolog the multi regional continuity hypothesis that proposes already living populations of hominins and local populations in asia europe and africa continued their indigenous evolutionary development from pre modern middle pleistocene forms to anatomically modern human jurmain et al 2011 281 whilst the complete replacement or out of africa hypothesis proposes that amh arose in africa 200 000 ya to completely replace those in europe and asia table 3 jurmain et al 2011 279 critical to the multi regional hypothesis are the tenets that i a level of gene flow between geographically separated populations prevented speciation ii all living humans derive largely from the species h erectus iii natural selection in regional populations is responsible for the regional variants found in extant populations and finally iv that the emergence of h sapiens was not restricted to one area per se but was a phenomenon that occurred throughout the geographic range where humans lived johanson 2001 1 table 3 timeline of major h sapiens discoveries question marks denote tentative dates jurmain et al 2011 413 click to enlarge critical to the complete replacement theory are that i h sapiens arose in one place highly likely to be east south africa ii h sapiens ultimately migrated out of africa and replaced all human populations without interbreeding and that iii modern human variation is a relatively recent phenomenon johanson 2001 1 although not all factors of the multiregional hypothesis cannot be falsified it seems prevalent that h sapiens originated in eastern africa with ethiopia so far providing the most stable dated site and dispersed to europe and asia from 65 000 ya onwards in various waves table 2 jurmain et al 2011 282 mellars 2006 9381 the two most securely dated sites in europe for amh are pecstera cu oase in romania at 42 000 ya and buran kaya iii in the crimea ukraine at 31 900 ya hoffecker 2009 16040 prat et al 2011 unsurprisingly hoffecker 2009 16040 notes that the issue of the mechanism of transition is a controversial topic in palaeoanthropology arguments have been made that amh crossed into eurasia via a levantine corridor with the earliest amh dates from skhul and qafzeh in israel at around 120 000 to 100 000 ya wood 2005 98 whilst recent work in north african aterian populations from around the same period are pointed out as being possible ancestors to at least some of the h sapiens who left africa during this period balter 2011 23 the palaeoanthropological evidence suggests that they the aterians possessed the right symbolic behaviour anatomy and favourable climatic conditions to be at least a contender for contributing to one of the waves of h sapiens leaving balter 2011 22 23 there are a variety of sites across europe after 40 000 ya that show a variety of evidence for amh presence including the triad of modern human behaviour with symbolic artefacts and modern skeletal morphology however we should not forget that europe was already populated with the h neandertalensis species prior and co existed with h sapiens for approximately 10 000 years or so hoffecker 2009 16040 wood 2005 110 this subject will be tackled shortly the most secured dates found in asia are from areas such as the sahul region conjoined landmass of australia papua new guinea and tasmania where it is possible amh occupied various areas wood 2005 111 112 it must be remembered that while the dwarf species h floresiensis survived up until 18 000 ya on the island of flores with temporal overlap between themselves and h sapiens it seems unlikely there was regional overlap from the archaeological evidence wood 2005 111 curnoe et a l 2012 1 note that the amh fossil record for east asia is at this time poorly recorded owing to a lack of detailed description rigorous taxonomy classification and a distinct lack of accurately dated fossils however there are a few key sites liujiang in southern china has produced a skeleton which although it lacks exact stratigraphic position has been dated to an estimated broad range from 153 30 000 ya whilst the niah cave child in east malaysia has been dated to 45 39 000 ya for the cranium from a recent field and lab program curnoe et al 2012 2 tianyuan cave just south of the zhoukoudian cave has fragmentary evidence of an amh crania and teeth which are dated to 40 000 ya with a possible mix of archaic and modern features the american and chinese team who excavated it have suggested it is evidence of interbreeding in china with resident archaic populations but suggest an african origin for the amh itself jurmain et al 2011 287 the above examples highlight problems in understanding the definition of amh both anatomically and behaviourally with the advent of dispersals from africa amh interacted with other hominids prominent of which are the neandertals in eurasia and the elusive denisovans in siberia krause et al 2010 hubin 2009 noonan 2010 zilhao 2006 genetic evidence is unravelling what it is to be an amh hawks et al 2007 and there is evidence to suggest that neandertals contributed up to 4 of non african modern human dna via gene flow green et al 2010 711 reich et al 2010 1057 roughly one third of neandertal mtdna genetic diversity dating from 70 000 to 38 000 ya is comparable to contemporary human populations briggs et al 2009 319 although noonan 2010 550 and herrera et al 2009 253 raise the flag of caution as the majority of neandertal remains were not collected with their regard to dna investigation whilst modern dna contamination despite the safeguards is still prevalent briggs et al 2009 321 postulate that low mtdna diversity throughout much of the neandertal lineage may indicate a low effective population size although it could be reflective of amh direct indirect influences as they spread from africa interbreeding or out competing for example herrera et al 2009 253 note that there are difficulties such as identifying haplotypes indicative of interbreeding nonetheless as zilhao et al 2010 1027 points out that a mid palaeolithic iberian neandertal sites shows distinct features associated with amh including symbolic behaviour with ochre and shells displaying evidence of body paint and organisation skills which that studies believes is the outcome of demographic pressure technology and social complexification within the neandertal species itself roebroeks et al 2012 2 figure 1 phylogenetic tree of complete mtdna rooted with chimpanzee and bonobo mtdna showing geographic origin of mtdna samples krause et al 2010 896 click to enlarge meanwhile krause et al 2010 896 provide evidence that the denisovans split before neandertal and amh at around 1 million ya whilst neandertals and h sapiens ancestors split around 690 000 to 550 000 ya jurmain et al 2011 270 pairwise nucleotide differences indicate that neandertals differ from modern humans at around 202 nucleotide positions whilst the denisovan individual differs at 385 positions krause et al 2010 895 which alongside the phylogenetic evidence figure 1 supports a deeper divergence of the denisovan hominin than between the closer related h sapiens and neandertal species there is the distinct possibility of admixture this is reinforced by the apparent coexistence of the surrounding area by neandertals amh and denisovans in the altai region at roughly the same time periods and by the fact that denisova populations contributed roughly 4 6 present day dna in amh melanesian populations this suggests they interacted with melanesian ancestors but probably not in the siberia region krause et al 2010 895 reich et al 2010 1053 the lack of complete remains and its physically limited location from this suspected new species at denisova cave limit our knowledge but tests are continuing if this hominin as hypothesised had a wide geographical range reich et al 2010 1059 the question must be asked why we haven t noticed it before interestingly abi rached et al 2011 94 highlight that the fact that as the amh eurasian populations mixed with archaic hominids adaptive introgression of vital immune system components human leukocytes antigen class 1 helped to provide a mechanism for rapid evolution the adapted introgression of the genes now represent more than half of the hla alleles in modern eurasians and were later introduced into african populations abi rached et al 2011 89 therefore the definition of amh must include evidence of interbreeding to some degree future genomic studies in other archaic hominins should provide more information relating to the relationships between species however it seems clear that gene flow was relatively common in the upper pleistocene reich et al 2010 1059 increased amh demographic growth and geographic spread dated from 80 000 ya to the present has led to rapid genetic evolutionary selective pressures on features including skin pigmentation adaptation to cold and diet amongst others hawks et al 2007 20756 some of the most dramatic have been associated with the uptake of agriculture during the neolithic period both in terms of our ability in coping with disease and changes from interaction via population density barnes et al 2011 848 this is partly the result of cultural and ecological reasons i e a biocultural pathway and hawks et al 2007 20756 20757 remark that in their study it was noted new adaptive alleles continued to reflect demographic growth that the neolithic and later periods would have experienced a rate of adaptive evolution 100 times higher than characterised most of human evolution two examples help highlight the effects of biocultural change in modern population coevolution of humans and cattle since the neolithic has resulted in distinct populations of modern humans becoming lactose persistence such as europeans whilst other populations such as african and asian adults are largely lactose intolerant jurmain et al 2011 313 this is through active selection of breeding cattle which inadvertently selected for the gene that produces lactose persistence in themselves jurmain et al 2011 313 this example shows the geographical distribution of lactose persistence is often related to a history of cultural dependency on fresh milk product...
