\nJustin Cook de la Universitatea din California, Merced, a folosit date despre fluxurile de popula\u0163ie migratoare pentru a estima compozi\u0163ia etnic\u0103 a 108 \u0163\u0103ri din Africa, Asia \u015fi Europa \u00een 1500. Apoi el estimeaz\u0103 care este propor\u0163ia popula\u0163iei care putea digera laptele, utiliz\u00e2nd date despre toleran\u0163a la lactoz\u0103 \u015fi a g\u0103sit c\u0103 \u0163\u0103rile din vestul europei aveau o rat\u0103 a toleran\u0163ei la lactoz\u0103 foarte ridicat\u0103 (96% Suedia), iar cele mai sc\u0103zute rate au fost g\u0103site \u00een \u0163\u0103rile sub-sahariene din Africa \u015fi \u00een \u0163\u0103rile din Asia de Sud-Est.<\/p>\n
\nConform teoriei, oamenii care puteau digera laptele au folosit resursele mai eficient dec\u00e2t cei care nu puteau digera laptele. Practic, ei puteau extrage energie lichid\u0103 de la animale, \u00een plus fa\u0163\u0103 de l\u00e2n\u0103, carne etc. Mai mult, laptele i-ar fi ajutat pe europeni cu gr\u0103simi benefice, proteine, vitamine \u015fi minerale, reduc\u00e2nd astfel bolile de care sufereau la vremea respectiv\u0103. De asemenea, dac\u0103 laptele era folosit pentru hr\u0103nirea bebelu\u015fului acesta putea fi \u00een\u0163\u0103rcat mai devreme, astfel reduc\u00e2nd timpul \u00eentre na\u015fteri.<\/p>\n
\nSociet\u0103\u0163ile care consumau lapte erau mai dense, ceea ce \u00eenseamn\u0103 c\u0103 \u015fi cre\u015fterea era accelerat\u0103 deoarece era mai u\u015for dezvoltarea infrastructurii, aplic\u0103rii legilor etc. Ora\u015fele se dezvolt\u0103, iar muncitorii se pot specializa \u015fi apar astfel tehnologii ce pot ajuta dezvoltarea societ\u0103\u0163ilor.<\/p>\n","protected":false},"excerpt":{"rendered":"
Oamenii pot digera lactoza, principalul element din lapte, cu ajutorul unei enizime numite lactaz\u0103. Dar dou\u0103 treimi din popula\u0163ie nu mai produce aceast\u0103 enzim\u0103 dup\u0103 ce au fost \u00een\u0163\u0103rca\u0163i.
