Phylogenetics is the study of the evolutionary history and relationships among different species or groups of organisms, based on their genetic and morphological characteristics. This involves constructing evolutionary trees, or phylogenies, to illustrate the evolutionary relationships between different species, and can provide insights into the origins and diversity of life on Earth.
Protein database is a collection of protein sequences and related information stored in a computer-readable format. It allows researchers to access information on the structure, function, and interactions of proteins. Protein databases are important tools for studying the proteome.
