A viewer capable of viewing multiple overlaid trees. All [23] FigTree: Simple Java tree viewer able to read newick and nexus tree files. Can be used to color branches and produce vector artwork. All [24] JEvTrace A multivalent browser for sequence alignment, phylogeny, and structure.
Species of the infraorder Cetacea A phylogenetic tree showing the relationships among cetacean families. [1]The evolution of cetaceans is thought to have begun in the Indian subcontinent from even-toed ungulates (Artiodactyla) 50 million years ago (mya) and to have proceeded over a period of at least 15 million years.

SplitsTree is a popular freeware program for inferring phylogenetic trees, phylogenetic networks, or, more generally, splits graphs, from various types of data such as a sequence alignment, a distance matrix or a set of trees.
Subtrees can also be displayed in its own tree explorer with all the same features and options. [38] The compute menu provides options for computing a condensed tree, a consensus tree, or a timetree with or without a molecular clock. [39] The file menu provides options for saving, exporting, printing, and exiting.
A phylogenetic tree visualized in the main window can be used for data access and visualization. The package contains additional tools for data import and export, sequence alignment, primary and secondary structure editing, profile and filter calculation, phylogenetic analyses, specific hybridization probe design and evaluation, and other ...
Phylogenetic trees generated by computational phylogenetics can be either rooted or unrooted depending on the input data and the algorithm used. A rooted tree is a directed graph that explicitly identifies a most recent common ancestor (MRCA), [citation needed] usually an inputed sequence that is not represented in the input.
The Tree of Life Web Project (ToL) is an Internet project providing information about the diversity and phylogeny of life on Earth. [1] [2] This collaborative peer reviewed project began in 1995, and is written by biologists from around the world. The site has not been updated since 2011, however the pages are still accessible.

A phylogenetic 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. [ 1 ] [ 2 ] In other words, it is a branching diagram or a tree showing the evolutionary relationships among various biological species or other entities based upon ...
