Animal kingdom is the biggest and the most diverse of most kingdoms. With the increase in human understanding there came a need to subdivide the subject more. Zoology was separated into invertebrate zoology and vertebrate zoology.
This division cannot make the studies simpler because greater than 90% of the living organisms were vertebrates. The classic zoologists were thinking about the discovery of new organisms while the zoologists of the twenty first century focused on how animals react to weather changes and temperature and the way they obtain energy for their life procedures. Experimentation and observations laid the basis for the subject. The development of zoology was slow however a steady process.
Zoology is the study of every aspect of the biology of animals, such as human beings and the numerous invertebrate and vertebrate animal species that populate our planet. Zoology majors study how animals function at the tissue, cellular, organismal and organ levels, the way they contribute to biodiversity, the way they have evolved and the way they interact with each other and with their physical environment.
The study of zoology contains not only learning what is presently known about animals however also learning the way to do research to improve our basic understanding about animals and to solve issues in many fields such as agriculture, medicine and ecology.
Students with a degree in zoology can pursue a number of careers in human and scientific research, veterinary medicine and education, development, environmental monitoring and regulation and private design and consulting.
Zoology is a broad field providing many career options for research, especially because there still is a whole lot to learn about it. A career in zoology offers an opportunity to make a difference to the planet's ecology through conservation work. Most zoologists are employed by universities and colleges, where they engage in research and teach students.
Generally, all zoology specializations involve work with animals, either in a lab or in the wild. Some zoologists study the whole organism although other zoologists study only parts of a living thing. Also, zoology is not only an observational pastime for natural history buffs; it involves analytical research and experimental laboratory elements, just as all other biological sciences do. As with other disciplines, zoologists work outdoors in the field and in laboratories using a multitude of scientific equipment.
Some zoologists carry out field research in harsh environments and remote areas, which can involve strenuous physical activity and primitive living circumstances.
