Man Landing on Madeira Could Be 4 Centuries Prior to Its Colonization by the Portuguese (video) Spanish National Research Council (CSIC) Share Print E-Mail Loading video... Caption Four centuries before its colonization by the Portuguese, man may have landed on Madeira Island. This can be deduced from a study led by the Spanish National Research Council (CSIC), based on the dating of some ancient mice bones found in a fossiliferous site in Ponta de São Lourenço. According to the results, published in the Proceedings of the Royal Society B journal, house mice may have landed on the island before 1036, most likely transported by a ship. The article suggests that the introduction of this species would result in an ecological disaster.
