Do you mean ' the universal common ancestor? '
A tool called a phylogenetic analysis software is used to root a phylogenetic tree.
The base root of a phylogenetic tree represents the common ancestor of all the species included in the tree. It is the starting point from which the evolutionary relationships and divergence of the different species are depicted.
mapping characters on a tree
Phylogenetic trees show the evolutionary relationships among organisms. The branching patterns in a phylogenetic tree represent the common ancestry of different species. Phylogenetic trees are constructed based on genetic, morphological, and behavioral data to infer evolutionary history.
To calculate the tree length of a phylogenetic tree, you add up the branch lengths between each pair of connected nodes or taxa in the tree. This total sum of branch lengths represents the tree length.
Neither. The leaves of the tree represent descendants; the root or base represents the common ancestor of all organisms in that tree. This says nothing about which have survived and which have become extinct, only which appeared first and which developed from it.
This tree would be seriously reticulated.

Phylogenetic tree
The kingdom Monera (bacteria) is typically considered to be at the bottom of the phylogenetic tree, as it is one of the most ancient and simple forms of life.
The x-axis of a phylogenetic tree represents time or evolutionary history, showing the sequence of events from past to present.
