Natural science can be divided into two main branches: life science and physical science. Life science is alternatively known as biology, and physical science is subdivided into branches: physics, chemistry, astronomy and Earth science. These branches of natural science may be further divided into more specialized branches (also known as fields).
This science is one of the two major branches of natural science, the other being physical science, which is concerned with non-living matter. 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.
Biology is the scientific study of life. [ 1 ] [ 2 ] [ 3 ] It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. [ 1 ] [ 2 ] [ 3 ] For instance, all organisms are made up of at least one cell that processes hereditary information encoded in genes , which can be transmitted ...
Cell biology – Branch of biology that studies cells – study of the different structures and functions of both eukaryote and prokaryote cells. Cetology – The study of whales, dolphins, porpoises, and other cetaceans – study of whales and dolphins.
Entomologist – scientific study of insects, a branch of arthropodology. Evolutionary biologist – sub-field of biology concerned with the study of the evolutionary processes that have given rise to the diversity of life on Earth. Geneticist – biologist who studies genetics, the science of genes, heredity, and variation of organisms.
The blue and orange subgroups are clades; each shows its common ancestor stem at the bottom of the subgroup branch. The green subgroup alone does not count as a clade; it is a paraphyletic group with respect to the blue group, because it excludes the blue branch which has descended from the same common ancestor. The green and blue subgroups ...
