One of the probable ways to determine how long ago any two species of bacteria diverged from each other is by drawing a phylogenetic tree.
Explanation:
- Phylogenetic tree are trees that show the ancestry of two species of interest and the relationship between them.
- The idea behind the construction of phylogenetic tree is darwins's "descent with modification theory".
- A phylogenetic tree is constructed using the similarities or differences in either physical characteristics, behavorial, or genetic buildup.
- Derived traits shared between the different species are the actual data used to construct a phylogenetic tree.
