Drawbacks of Ernst haeckal in biological classification
Answers
Answer:
Explanation:
Classification is the arrangement of organisms into taxonomic groups known as taxa on the basis of similarities or relationships.
Closely related organisms (i.e., organisms having similar characteristics) are placed into the same taxon.
Organisms are categorized into larger groups based on their similarities and differences.
The classification of living organisms is a complex and controversial subject because of which different taxonomic classification schemes existed at different times.
In his classification scheme, Linnaeus recognized only two kingdoms of living things: Animalia and Plantae.
At the time, microscopic organisms had not been studied in detail. Either they were placed in a separate category called Chaos or, in some cases, they were classified with plants or animals.
As the knowledge of the properties of various groups of microbial life exploded, it became apparent that at this level of biological knowledge a division of the living world into two kingdoms cannot really be maintained on a logical and consistent ground.
Then in the 1860s, the German investigator Ernst Haeckel proposed a three-kingdom system of classification.
