There are no organisms that cannot be parasi-tized. The relationship between a parasite and its host species most of the time do not result in damage or disease to the host. However, in a parasitic disease the presence of a given parasite is always necessary, at least in a given moment of the infection. Some parasite species that infect humans were inherited from pre-hominids, and were shared with other phylogenetically close host species, but other parasite species were acquired from the environment as humans evolved. Human migration spread inherited parasites throughout the globe. To recover and trace the origin and evolution of infectious diseases, paleoparasitology was created. Paleoparasitology is the study of parasites in ancient material, which provided new information on the evolution, paleoepidemiology, ecology and phylogenetics of infectious diseases.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Paleoparasitologia: a origem dos parasitas humanos&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Resumo&lt;/strong&gt;: parasitismo &amp;eacute; composto por tr&amp;ecirc;s subsistemas: o parasito, o hospedeiro e meio ambiente. N&amp;atilde;o existe organismo que n&amp;atilde;o possa ser parasi-tado. A rela&amp;ccedil;&amp;atilde;o entre um parasito e suas esp&amp;eacute;cies de hospedeiro n&amp;atilde;o resulta, na maior parte das vezes, em dano ou doen&amp;ccedil;a ao hospedeiro. Entretanto, numa doen&amp;ccedil;a parasit&amp;aacute;ria, a presen&amp;ccedil;a de um determinado parasito &amp;eacute; sempre necess&amp;aacute;ria, pelo menos em um determinado mo-mento&amp;nbsp; da&amp;nbsp; infec&amp;ccedil;&amp;atilde;o.&amp;nbsp; Algumas&amp;nbsp; esp&amp;eacute;cies&amp;nbsp; de&amp;nbsp; parasitos&amp;nbsp; que&amp;nbsp; infectam&amp;nbsp; humanos&amp;nbsp; foram&amp;nbsp; herdados&amp;nbsp; dos&amp;nbsp; pr&amp;eacute;-homin&amp;iacute;deos,&amp;nbsp; e&amp;nbsp; foram&amp;nbsp; compartilhados&amp;nbsp; com outras esp&amp;eacute;cies de hospedeiro filogeneticamente pr&amp;oacute;ximas, mas outras esp&amp;eacute;cies foram adquiridas pelo meio ambiente &amp;agrave; medida que os humanos se desenvolveram. As migra&amp;ccedil;&amp;otilde;es humanas espalharam os parasitos adquiridos por todo o mundo. Para recuperar e tra&amp;ccedil;ar a origem e evolu&amp;ccedil;&amp;atilde;o das doen&amp;ccedil;as infecciosas foi criada a paleoparasitologia. Paleoparasitologia &amp;eacute; o estudo dos parasitos em materiais antigos, que trouxe novas informa&amp;ccedil;&amp;otilde;es na evolu&amp;ccedil;&amp;atilde;o, paleoepidemiologia, ecologia e filogen&amp;eacute;tica das doen&amp;ccedil;as infecciosas.&lt;/p&gt;
