easternmost presence recorded denisova cave siberia °e southeast chinese maba man skull shares several physical attributes neanderthals although may result convergent evolution rather neanderthals extending range pacific ocean.northernmost bound generally accepted °n unambiguous sites known –°n although difficult assess glacial advances destroy human remains palaeoanthropologist trine kellberg nielsen argued lack evidence southern scandinavian occupation least eemian interglacial due former explanation lack research area.middle palaeolithic artefacts found °n russian plains likely attributed modern humans.study claimed presence homo year old californian cerutti mastodon site north america largely considered implausible.it unknown rapidly fluctuating climate last glacial period dansgaard–oeschger events impacted neanderthals warming periods would produce favourable temperatures encourage forest growth deter megafauna whereas frigid periods would produce opposite.however neanderthals may preferred forested landscape.
Neanderthal
populations may peaked cold extreme intervals marine isotope stages respectively thousand years ago saale glaciation.possible range expanded contracted ice retreated grew respectively avoid permafrost areas residing certain refuge zones glacial maxima.israeli anthropologist israel hershkovitz colleagues suggested thousand years old israeli nesher ramla remains feature mix neanderthal ancient h. erectus traits represent one source population recolonised europe following glacial period.population like modern humans neanderthals probably descended small population effective population—the number individuals bear father children—of approximately.however neanderthals maintained low population proliferating weakly harmful genes due reduced effectivity natural selection.various studies using mtdna analysis yield varying effective populations remaining constant steadily increasing years ago declining extinction.
Neanderthal
however agree low population may less th contemporary human populations western europe possibly neanderthals much lower fertility rates.estimates giving total population higher tens thousands contested.consistently low population may explained context boserupian trap populations carrying capacity limited amount food obtain turn limited technology.innovation increases population population low innovation occur rapidly population remain low.consistent apparent year stagnation neanderthal lithic technology.in sample neanderthals based abundance young mature adults comparison age demographics age died reaching .

Neanderthal
nonetheless neanderthals temperate climates—such iberia—still retain hyperarctic physique.english anthropologist john stewart colleagues suggested neanderthals instead adapted sprinting evidence neanderthals preferring warmer wooded areas colder mammoth steppe dna analysis indicating higher proportion fasttwitch muscle fibres neanderthals modern humans.explained body proportions greater muscle mass adaptations sprinting opposed enduranceoriented modern human physique persistence hunting may effective hot climates hunter run prey point heat exhaustion hyperthermia.longer heel bones reducing ability endurance running shorter limbs would reduced moment arm limbs allowing greater rotational force wrists ankles without extra exertion rotating muscles elbows knees increasing speed muscles contracted causing faster acceleration.american palaeoanthropologist erik trinkaus made note alternate explanation considered less likely.

trinkaus concluded neanderthals instead injured way contemporary humans interpersonal violence.study looking neanderthal specimens argued high trauma rates instead caused animal attacks found sample victims bear attacks big cat attacks wolf attacks totalling positive cases .cases hyaena attacks although hyaenas still nonetheless probably attacked neanderthals least opportunistically.intense predation probably stemmed common confrontations due competition food cave space neanderthals hunting carnivores.low population caused low genetic diversity probably inbreeding reduced populations ability filter harmful mutations inbreeding depression.however unknown affected single neanderthals genetic burden thus caused higher rate birth defects modern humans.
