Background
What is Phylogeny? Phylogeny is the history of an organisms lineage and the change it undergoes over time [1]. Phylogeny and phylogenetics are useful tools when investigating a gene of unknown function or unknown origin. Phylogenetics can help us understand how genes, genomes and species evolve [2].
Maximum likelihood tree of the ARNT gene
Discussion
This maximum likelihood tree for the ARNT gene shows the closest relationship between humans and mice, the model organism with the most similar cardiovascular system to humans. The only other model organisms that ARNT was found in were those with some sort of cardiovascular system, showing there is a good possibility that ARNT is somehow involved with the heart.
