Biology is the scientific study of life.It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are composed of at least one cell that processes hereditary information encoded in genes, which can be transmitted to future generations.
Artificial life is the simulation of any aspect of life, as through computers, robotics, or biochemistry. [169] Synthetic biology is a new area of biotechnology that combines science and biological engineering .
Biology is the overall natural science that studies life, with the other life sciences as its sub-disciplines. Some life sciences focus on a specific type of organism. For example, zoology is the study of animals, while botany is the study of plants.
Quantitative genetics – study of phenotypes that vary continuously (in characters such as height or mass)—as opposed to discretely identifiable phenotypes and gene-products (such as eye-colour, or the presence of a particular biochemical). Marine biology – study of ocean ecosystems, plants, animals, and other living beings.
Evolutionary biology is the subfield of biology that studies the evolutionary processes such as natural selection, common descent, and speciation that produced the diversity of life on Earth.
The new study incorporated over a thousand newly discovered bacteria and archaea. [32] [33] [34] In 2022, the fifth version of TimeTree was released, incorporating 4,185 published studies and 148,876 species, representing the largest timetree of life from actual data (non-imputed). [35]
In biology, taxonomy (from Ancient Greek τάξις () 'arrangement' and -νομία () 'method') is the scientific study of naming, defining (circumscribing) and classifying groups of biological organisms based on shared characteristics.
