Career in Systematics/Taxonomy – Job Scope/Skills Needed & Research Opportunities

Biodiversity is the key feature of life on earth and the study of this biodiversity comes under Systematics (Taxonomy), which mainly focuses on the diversification of lineages all along the time. It deals with new species discovery which is the basic units of biodiversity, restructuring the interaction/relationship patterns among the species at successively higher levels, classification of species according to the identified pattern and naming (taxonomy), and principally applies this knowledge to monitor and analyze changes in the organism through time. Systematics also includes specimen collection – plants, insects, photographs, etc. – their maintenance and record-keeping. These type of biodiversity collections are also known as a museum.

Long-time back people had the basic idea about the differences among the existing organisms and in fact many extinct organisms from the fossils. But it was in the middle of the 20th century when biologists understood the concept of change in character throughout time which leads to the development of an advanced form of an organism- in simple words they understood the evolution. This formed the basis of classification by identifying the phylogenetic relationship which is a cladistic approach. The approach requires identifying the advanced character or synapomorphy and using it to generate phylogenetic relationship among organisms and further classify the organisms. Recent years many refinements have been made in the methodology from character analysis, hypothesis construction, testing of hypothesis to further application.

This article discusses Career in Systematics/Taxonomy – its Job Scope / Skills Needed & Research Opportunities available.

Roles of Systematics in Modern Biology

Before seeking a Career in Systematics/Taxonomy, one must understand the role it plays in modern biology. Systematics (Taxonomy) is a sub-topic under biology which has proved to be an important field in modern biology. It can shed light on some specific aspects of modern biology which can be summarized as follows:

1. Documentation of earth’s biodiversity:

A significant job of systematics is the search of new species and mapping of biodiversity. This involves extensive fieldwork where samples known as specimens are collected, preserved, documented and analyzed. Comparison with other specimens helps to determine the similarities and differences. After identification of the species, naming is done according to the rules of nomenclature for that group. A phylogenetic relationship is also determined which helps in the classification of the new organism. Such biodiversity collections document regional flora and fauna and thus provide information about worldwide biodiversity, its changes over time due to many biotic and abiotic factors.

2. Construction of evolutionary history:

Systematics (Taxonomy) helps to understand the similarities and dissimilarities between organisms existing or extinct. These comparative studies provide information about the changes in character with which an evolutionary history of life could be constructed. This possible via the construction of a phylogenetic tree which gives an indication of the relationships between taxa and the character transformation. Evolution has been found to be essentially closely associated with systematics.

3. The systematic study helps in predicting shared characters in organism database:

The phylogenetic database provides information regarding the ancestry and shared characters among the species. This could be useful in predicting additional taxa which might possess a similar trait of interest. Any important resource which might be costly could be replaced by a less costly source with the help of database search in the related taxa. As such it doesn’t guarantee success, but the search window could be minimized by looking into the related species.

4. Conservation of Biodiversity:

Understanding the relationship between species, organisms, taxa, etc. and their evolution is important for conservation. For a Career in Systematics/Taxonomy – Biodiversity knowledge plays a key role. With the passage of time and changes in abiotic factors, the biodiversity of the earth and of a specific region is changing. In order to maintain the species on earth and increase the diversity, systematics would help to identify the major taxa or species which needs to be conserved as it might be serving an important role. Conserving these species or groups would help in the survival of many other related organisms and thus maintain the diversity and eventually help to maximize it with time. Altogether it could serve in the sustainable development of human beings.

5. Predicting the geographical history of the earth:

Throughout the history of the earth, the continents had constantly shifted their position and even changed their shapes. This was identified by the study of life on earth through different time intervals. Mainly study of fossils helped to develop the geological time scale, which provides information about the emergence, distribution, and extinction of species along with the arrangement of landmasses. Like the widespread distribution of dinosaur fossils indicate that during that era the entire continents were fused together as a single landmass. Many such geological events could be identified through systematics alone.
