I was reading a machine learning math book and it mentioned matrix phylogeny. Looking at videos online, phylogeny is integral to biology, which I don't know much about, so I am going to try to learn more about it.
A phylogenic tree, phylogeny, or evolutionary tree is a graphical representation which shows the evolutionary history between a set of species or taxa during a specific time.
It is a branching diagram of tree showing the evolutionary relationships among various biological species or other entities based upon similarities and differences in their physical or genetic characteristics. In evolutionary biology, all life on Earth is theoretically part of a single phylogenetic tree, indicating common ancestry. Phylogenetics is the study of phylogenetic trees. The main challenge is to find a phylogenetic tree representing optimal evolutionary ancestry between a set of species or taxa.
Phylogenetic trees may be rooted or unrooted. In a rooted phylogenetic tree, each node with descendants represents the inferred most recent common ancestor of those descendants, and the edge lengths in some trees may be interpreted as time estimates. Each node is called a taxonomic unit. Unrooted trees illustrate only the relatedness of the leaf nodes and do not require the ancestral root to be known or inferred.
Early representations of branching phylogenetic trees include a paleontological chart showing the geological relationships among plants and animals in the book Elementary Geology by Edward Hitchcock in 1840. Charles Darwin featured an evolutionary tree in his 1859 book On the Origin of Species.
