This question is far from being resolved because speciation is at work in current biodiversity and the taxa of specific rank are therefore not certain species, but rather hypotheses of species that need to be tested. Darwin was already emphasising the importance of \u00abdoubtful species\u00bb in his argument about variation. We<br \/>Let us illustrate this property of living organisms to resist classification with the example of fuzzy taxa. These can be summarised in two main types, the syngamon and incipient species. The frequency of gene flow between taxa of specific rank, and the ecological and evolutionary role of introgression, show that uncertain species are a major aspect of biodiversity issues.<\/p><p>\ud83d\udd2c <a href=\"https:\/\/sciencepress.mnhn.fr\/sites\/default\/files\/articles\/pdf\/naturae2025a15.pdf\" target=\"_blank\" rel=\"noopener\"><strong data-start=\"1241\" data-end=\"1311\">A must-see for a better understanding of the complexity of living things!<\/strong><\/a><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-4758375 e-con-full e-flex e-con e-child\" data-id=\"4758375\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-ba434c5 elementor-widget elementor-widget-image\" data-id=\"ba434c5\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"593\" height=\"805\" src=\"https:\/\/www.imbe.fr\/wp-content\/uploads\/2025\/12\/naturae-2025.jpg\" class=\"attachment-large size-large wp-image-9823\" alt=\"\" srcset=\"https:\/\/www.imbe.fr\/wp-content\/uploads\/2025\/12\/naturae-2025.jpg 593w, https:\/\/www.imbe.fr\/wp-content\/uploads\/2025\/12\/naturae-2025-221x300.jpg 221w, https:\/\/www.imbe.fr\/wp-content\/uploads\/2025\/12\/naturae-2025-9x12.jpg 9w\" sizes=\"(max-width: 593px) 100vw, 593px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"<p>L\u2019esp\u00e8ce incertaine et les taxons flous La \u00ab bonne \u00bb d\u00e9finition de l\u2019esp\u00e8ce est r\u00e9guli\u00e8rement remise en question par les progr\u00e8s des connaissances sur l\u2019\u00e9volution et la sp\u00e9ciation.
