definition of biology by different authors
Researchers often use inductive and deductive reasoning in tandem to advance scientific knowledge (Figure 1.7). Biologists study the living world by posing questions about it and seeking science-based responses. These differences were heavily affected by socially determined behaviours such as those concerning marriage patterns. Since the 1960s fertility has been intentionally diminished in many developing countries, and remarkably rapid reductions have occurred in the most populous, the Peoples Republic of China. Many times, science does not operate in a linear fashion. He was the first scientist, proposed the relation of species and organize them accordingly. There are numerous branches and subdisciplines of biology, but here is a short list of some of the more broad fields that fall under the umbrella of biology: Biochemistry: The study of the chemical processes that take place in or are related to living things, according to the Biochemical Society.

For example, a person might have genitals or internal sex organs that fall outside of typical binary categories. Many biologists may work in the lab and in the field for example, scientists may collect soil or water samples from the field and analyze them further in the lab, like at North Carolina University's Soil and Water Lab. For example, bioethicists may examine the implications of gene editing technologies, including the ability to create organisms that may displace others in the environment, as well as the ability to design human beings. Another example of the link between basic and applied research is the Human Genome Project, a study in which researchers analyzed and mapped each human chromosome to determine the precise sequence of DNA subunits and each gene's exact location.

These terms all refer to the idea of living variation, from genes and traits, to species, and to ecosystems. Biologists can work in many different fields, including research, healthcare, environmental conservation and art, according to the American Institute of Biological Sciences. This is because it is relatively easy to apply the scientific method to disciplines such as physics and chemistry, but when it comes to disciplines like archaeology, psychology, and geology, the scientific method becomes less applicable as repeating experiments becomes more difficult.
