Bioinformatics is broadly defined as the use of computers to analyse biological information. The most common form of bioinformatics is studying the vast amounts of DNA and protein sequence that are now available. However, there are many other possible applications of computers in biology, such as simulating populations, analysing experimental gels and storing information about the phenotypes of mutant organisms.

Cell biology lies at the center of the biological sciences, constituting the bridge between the sub-cellular, molecular levels of organization and the super-cellular, tissue-based and organismal levels. Historically, cell biology has relied upon biochemical and biophysical methods, microscopy, cell manipulation and pharmacological intervention for its progress. However, with the advent of modern techniques in molecular genetics and recombinant DNA technology, cell biology has become more closely allied to the fields of molecular and developmental biology and genetics. Much recent progress in cell biology also derives from discovery of new chemical compounds with effects on cellular processes. Furthermore, cell biology is at the heart of research on cancer, and as the understanding of the cell grows, cell biology has emerged as an important discipline in the biomedical sciences and medicine.

The development of an organism or tissue from an egg, seed, spore or other type of progenitor cell is the subject of developmental biology. Developmental biology encompasses the field of embryology - the study of the embryo - and touches upon a number of other disciplines, including cell and molecular biology, genetics and biochemistry. Most research in developmental biology focuses on model biological systems for which powerful tools of manipulation exist, each offering its own advantages. Modern molecular studies on model systems have revealed a remarkable degree of conservation of genes and proteins involved in development between even distantly related organisms, contributing to a new awareness of the relatedness of all species. Research in developmental biology has contributed immensely to our understanding of hereditary diseases affecting human development, and the promise of better treatments or cures for human diseases based on basic research in other species is very exciting.

This category is for scientific sites about evolution in biology. Evolution is the process by which living things change over generations. Evolutionary biology is the study of how and why evolution occurs. An organism inherits traits from its parents through the genome. Mutations in these genes and/or the way they are read, or not read, can produce a new trait in the offspring. If a new trait makes these offspring better suited to their environment, they will be more successful at surviving and reproducing. This process is called natural selection, and it causes useful traits to become more common. The theory of evolution by natural selection was first proposed by Charles Darwin in his book “On the Origin of Species”, written in 1859.

This category is reserved for sites about the Biology of Evolution. Sites opposing the Theory of Evolution may be submitted to sub-categories of Science: Anomalies and Alternative Science such as Criticism of Darwinism or Creationism.
