what kind of molecular information is commonly used to study phylogeny among photosynthetic organisms that diverged from a common ancestor relatively long ago?



Answer :

DNA sequencing was developed several years before molecular phylogenetics. It is developed from Linnaeus's extensive use of the conventional approach of classifying species based on their similarities and differences in the 18th century.

The branch of phylogeny known as molecular phylogenetics examines genetic, hereditary molecular variations, primarily in DNA sequences, to learn more about the evolutionary relationships of organisms. These investigations allow for the identification of the mechanisms that have led to species diversity. Phylogenetic trees are used to represent the findings of molecular phylogenetic analyses. One component of molecular systematics is molecular phylogenetics.
