How does an unknown species become a known species?

The process of discovering and naming a previously unknown species is known as species description. When a scientist believes they have found an unknown species, they will typically follow these steps:

Collect specimens: The scientist will collect specimens of the organism, including both adults and juveniles, if possible. These specimens will be used for morphological analysis and DNA sequencing.

Morphological analysis: The scientist will examine the specimens in detail, taking measurements and comparing them to similar known species. This analysis can help to identify distinguishing features that separate the unknown species from other known species.

DNA sequencing: The scientist will extract DNA from the specimens and sequence it. This information can help to determine the phylogenetic relationship of the unknown species to other known species.

Write a description: The scientist will write a detailed description of the unknown species, including information on its morphology, DNA sequence, and ecological niche. This description will be published in a scientific journal.

Peer review: The description will be peer-reviewed by other scientists to ensure that it is accurate and complete. If the description is accepted, the unknown species will be added to the scientific literature and given a scientific name.

The process of species description can take several years, and it can be challenging to obtain the necessary specimens and data. However, it is an important part of scientific research and contributes to our understanding of the diversity of life on Earth.
