Biologist Job Description

A biologist is a scientist who studies living organisms to understand and explain their structures and functions, and how they interact with their environment. Their job involves observing and experimenting on living things in their natural habitat or in a laboratory to establish facts about them.

A biologist should be curious, analytical, methodical, patient and persistent, and have the ability to handle and operate scientific equipment. They should also be able to communicate effectively and work well independently and in a team.

Famous biologists include Hippocrates (the father of western medicine), Robert Brown (discovered the cell nucleus), Aristotle (classified organisms into a “ladder of life”), Charles Darwin (theory of evolution), Louis Pasteur (pasteurization of milk and wine), and Antonie Van Leeuwenhoek (father of microbiology).
