Summary Introduction
Introduction: The phylogenetic tree is a branching diagram that shows the pattern of evolutionary descent of different organisms. It paves the way to know the genetical and physiological relationship between different species or groups of organisms.

When reading a phylogenetic tree, which of the following is true regarding the evolutionary
relationships among the taxa represented on the tree?
Taxa located at adjacent tips of the branches are always more closely related to each other than to other taxa
on the tree. Therefore, a species is always equally related to the taxon on the branch immediately to the right
it and the taxon on the branch immediately to the left of it
The branch lengths always represent the amount of morphological change between taxa
The internal nodes (branching points) of the tree represent the most recent common ancestors of the taxa
connected by the branches
The position of taxa on the tree is completely arbitrary and does not reflect their evolutionary relationships
Which of the following is FALSE regarding phylogenetic trees?
1) The branch lengths on the tree are scaled to molecular (DNA) changes and/or time.
2)Phylogenetic trees have shown us that there is much more bacterial diversity compared to eukaryotes.
3) Phylogenetic trees show the evolutionary relatedness of different organisms.
4). The branch lengths on the tree depict abiotic and biotic factors affecting speciation.
In the figure, the letters A-G represent individual species that all descended from a common ancestor.

A is more closely related to D than it is to C.
G is more closely related to A than it is to F.
D is more closely related to E than it is to C.

- Below is an example of a particular kind of phylogenetic tree called a chronogram. Chronoograms are named because the length of the branches represents different lengths of time. Nodes are represented by vertical lines, and branches with horizontal ones. They can be arranged horizontally, with the most recent evolutions on the right.
