Verified Answer :

Histrionicus

Answer:

The correct answer is option D. increased knowledge of genetics leads to reclassification.

Explanation:

The classification system was initially was made on the basis of the similarities in their physical, internal characters and their habitats. Classification systems are always subject to update, based on the different factors.

The increased knowledge of the genome and the DNA is helping to tell that the species or organisms look different in several ways are actually closely related or share the ancestry.

Thus, the correct answer is option D.

Classification systems change over due to increased knowledge of genetics leads to reclassification.


Further Explanation:

The taxonomic classification system or Linnaean system was invented by Carl Linnaeus, who was a Swedish zoologist, botanist, and also a physician and he used a hierarchical model. Starting from the point of origin, the groups started to become more specific, unless one branch ends as a single species. There are eight levels of classification, namely, Kingdom, Domain, Class, Phylum, Family, Order, Genus, and Species. Through classification, scientists can group living organisms based on their similarities.


Species are as specific as one may get. The main criteria of the organism to be positioned in the specific species are the ability to breed with other organisms of the same species. The classification system always develops according to the improvement in science. Classification systems can vary according to experts who present them and can experience changes along with the latest findings.
