A biologist is a scientist who conducts research in biology. Biologists are interested in studying life on Earth, whether it is an individual cell, a multicellular organism, or a community of interacting populations. They usually specialize in a particular branch (e.g., molecular biology, zoology, and evolutionary biology) of biology and have a specific research focus (e.g., studying malaria or cancer). # ISO certification in India

Biologists who are involved in basic research have the aim of advancing knowledge about the natural world. They conduct their research using the scientific method, which is an empirical method for testing hypotheses. Their discoveries may have applications for some specific purpose such as in biotechnology, which has the goal of developing medically useful products for humans.

In modern times, most biologists have one or more academic degrees such as a bachelor’s degree plus an advanced degree like a master’s degree or a doctorate. Like other scientists, biologists can be found working in different sectors of the economy such as in academia, nonprofits, private industry, or government.

History

Francesco Redi, founder of biology.

Francesco Redi, the founder of biology, is recognized to be one of the greatest biologists of all time.Robert Hooke, an English natural philosopher, coined the term cell, suggesting plant structure’s resemblance to honeycomb cells.

Charles Darwin and Alfred Wallace independently formulated the theory of evolution by natural selection, which was described in detail in Darwin’s book On the Origin of Species, which was published in 1859. In it, Darwin proposed that the features of all living things, including humans, were shaped by natural processes of descent with accumulated modification leading to divergence over long periods of time. The theory of evolution in its current form affects almost all areas of biology.Separately, Gregor Mendel formulated in the principles of inheritance in 1866, which became the basis of modern genetics.

In 1953, James D. Watson and Francis Crick described the basic structure of DNA, the genetic material for expressing life in all its forms, building on the work of Maurice Wilkins and Rosalind Franklin, suggested that the structure of DNA was a double helix.

Ian Wilmut led a research group that in 1996 first cloned a mammal from an adult somatic cell, a Finnish Dorset lamb named Dolly.

Education

An undergraduate degree in biology typically requires coursework in molecular and cellular biology, development, ecology, genetics, microbiology, anatomy, physiology, botany, and zoology.Additional requirements may include physics, chemistry (general, organic, and biochemistry), calculus, and statistics.

Students who aspire to a research-oriented career usually pursue a graduate degree such as a master’s or a doctorate (e.g., PhD) whereby they would receive training from a research head based on an apprenticeship model that has been in existence since the 1800s.Students in these graduate programs often receive specialized training in a particular subdiscipline of biology.
