Abstract
Starting with Linné and up to nowadays taxonomy has been developing
constantly and it has appealed to almost all of the domains of biologic
sciences. However, during the last 100 years it has made an extraordinary leap,
as a consequence of the broad changes which occurred in electronic microscopy,
biochemistry, genetics, ecology and the mathematical processing of populational
data. This evolution is most obvious at the level of microscopic organisms. As
an example I have shown the qualitative and quantitative
leap achieved at the level of unicellular eukaryotes – protoctists,
which I have highlighted with examples from the study of testacean
rhizopods. The cultures of the various species have proven to be highly useful,
as well at the variability data at the level of the populations and those
obtained from paleontology.
Keywords: species, correlations bwetween taxonomy and other domains of biology,
genetic phylogeny, testaceans.
