The set of species derived from one common ancestor.
To build phylogenetic trees, a variety of data can be employed, including genetic information, mitochondrial DNA sequences, ribosomal RNA genes, and any relevant genes, as well as morphological information such as structural characteristics, organ kinds, and specific skeletal arrangements
<h3>What is a Phylogenetic tree ?</h3>
A phylogenetic tree, also called a phylogeny, is a diagram that shows the evolutionary branches from which various species, creatures, or genes have descended from one another.
- A phylogenetic tree can be used to track a species' evolutionary history back via the tree's branches and find their common ancestors along the way. 
- A lineage may preserve some of its ancestors' characteristics over time, but it will also change over time to accommodate the environment.

Scientist, a fact is something that can be tested by anyone with the proper skill and equipment, and that repeatedly and reliably gives the same result every time. A scientific theory is a body of knowledge based on facts that describes their interaction in the simplest possible way
