Neandertal\u00ebt u shfaq\u00ebn rreth 250,000 vjet m\u00eb par\u00eb nga popullatat para-neandertale (nga 500,000 deri n\u00eb 250,000 vjet m\u00eb par\u00eb). K\u00ebto popullata endeshin n\u00ebp\u00ebr Euroazi. P\u00ebr shum\u00eb vite, studiuesit besonin se nd\u00ebrsa para-neandertal\u00ebt evoluuan n\u00eb neandertal\u00ebt e hersh\u00ebm dhe m\u00eb pas n\u00eb neandertal\u00ebt klasik\u00eb, kishte pak ndryshime evolucionare.<\/p>\n
Megjithat\u00eb, zbulime t\u00eb reja t\u00eb publikuara n\u00eb Nature Communications mund ta ndryshojn\u00eb k\u00ebt\u00eb besim t\u00eb zakonsh\u00ebm, pasi analiza e vesh\u00ebve t\u00eb neandertal\u00ebve tregon se mund t\u00eb ket\u00eb pasur nj\u00eb humbje t\u00eb madhe gjenetike gjat\u00eb k\u00ebsaj periudhe evolucionare.<\/p>\n
\u00a0<\/p>\n
Nj\u00eb ekip k\u00ebrkimor nga Spanja analizoi mostra t\u00eb ADN-s\u00eb nga fosilet e neandertal\u00ebve dhe vuri re nj\u00eb humbje gjenetike midis neandertal\u00ebve t\u00eb hersh\u00ebm dhe atyre klasik\u00eb.<\/p>\n
\u00a0<\/p>\n
Kjo lloj humbjeje gjenetike quhet ngushtim gjenetik dhe ndodh si pasoj\u00eb e reduktimit t\u00eb popullat\u00ebs. Sipas t\u00eb dh\u00ebnave t\u00eb mbledhura, ky ngushtim filloi rreth 110,000 vjet m\u00eb par\u00eb.<\/p>\n
\u00a0<\/p>\n
Para k\u00ebtij ngushtimi, disa studiues besonin se kishte ndodhur nj\u00eb ngjarje e ngjashme q\u00eb \u00e7oi n\u00eb zhvillimin e ADN-s\u00eb s\u00eb neandertal\u00ebve nga para-neandertal\u00ebt. P\u00ebr k\u00ebt\u00eb arsye, shum\u00eb shkenc\u00ebtar\u00eb mendonin se neandertal\u00ebt e hersh\u00ebm dhe ata klasik\u00eb kishin nj\u00eb diversitet gjenetik m\u00eb t\u00eb ul\u00ebt sesa para-neandertal\u00ebt e tyre paraardh\u00ebs.<\/p>\n

K\u00ebto kanale t\u00eb mbushura me l\u00ebng ndihmojn\u00eb n\u00eb ruajtjen e ekuilibrit.<\/p>\n

Sipas studimit, rezultatet e analiz\u00ebs morfologjike ishin t\u00eb ngjashme me ato t\u00eb krahasimeve t\u00eb ADN-<\/p>\n
