Un arbre filogen\u00e8tic \u00e9s un diagrama ramificat que permet modelitzar les relacions de parentiu entre un grup d\u2019organismes.\u00a0 Aquestes representacions gr\u00e0fiques han revolucionat l\u2019estudi de la biologia evolutiva, ja que permeten, entre altres, definir i establir una esp\u00e8cie determinada o provar hip\u00f2tesis evolutives.\u00a0 Els arbres poden construir-se utilitzant car\u00e0cters morfol\u00f2gics o moleculars o tots dos.<\/span><\/p>\n

L\u2019activitat que proposem a l\u2019alumnat de Biologia de 4<\/span>t<\/span> d\u2019ESO\u00a0 \u00e9s elaborar una filog\u00e8nia artificial basada en la morfologia. Els \u00aborganismes\u00bb utilitzats s\u00f3n objectes met\u00e0l\u00b7lics (claus, xinxetes, cargols, clips…),\u00a0 impresos en un document. Es pret\u00e9n que siguin capa\u00e7os de trobar \u00ables relacions evolutives\u00bb entre els diferents objectes, tenint en compte que els organismes que m\u00e9s s\u2019assemblen estan, probablement, m\u00e9s relacionats que altres que no s\u2019assemblen tant . De la mateixa manera, les formes m\u00e9s simples donen lloc a les formes m\u00e9s complexes i les m\u00e9s petites a les m\u00e9s grans.<\/span><\/p>\n

Tot i que, evidentment, l\u2019arbre geneal\u00f2gic produ\u00eft \u00e9s artificial, els problemes i les preguntes que sorgeixen s\u00f3n similars a les que es plantegen els cient\u00edfics que els elaboren.<\/span><\/p>\n
