Phylogeny is the evolutionary history of a particular taxonomic group which is usually a species. A taxonomic group is apart of the biological classification of organisms. E.g: There is the Kingdom, Phylum, Class, Order, Family, Genus or Species. The Grey-Headed Flying Fox is apart of the Animalia Kindom, Chordata Phylum, Mammalia Class, Chiroptera Order, Pteropodidae Family, Pteropus Genus and the P. poliocephalus Species.

The Tree of Life is an idea relating to the interconnectedness between all of life on earth, and all things evolutionary.

The Grey-Headed Flying Fox, as suggested earlier belongs to the Chiroptera Order. Within this Order, there are also 4 other extinct species. These are; Icaronycteris, Archaeonycteris, Hassianycteris and Paleochiropteryx. This show the Phylogeny of the species, or rather more, the Order of Chiroptera.

This diagram shows the history of the Grey-Headed Flying Fox, where the original Dragon, is linked to the Wyvern on the same tree, which shows in brackets that it had 'bat-like' wings. This indicates that somehwere during evolution, a Wyvern Dragon, evolved into a much smaller creature, such as the Grey-Headed Flying Fox.

Colugo's, or also known as flying lemurs, are not related to the Grey-Headed Flying Fox in any way. However, there are a couple of analogous structures between the two, that are quite similar. Although a Colugo is not a true Lemur, nor is it a bat, it has excess skin between it's arms and legs which help it to glide from higher levels to the lower levels. However, unlike other gliders etc, the Colugo has webs between its toes, which increase it's chances of gliding further. The webs between these toes are there to increase the surface area, not unlike the wings of a bay, or, flying fox. The Grey-Headed Flying Fox, and the Flying Lemur, are not closely related at all. Both are in the same infra-class; Eutheria, however they both then seperate in the Tree of Life, into two different Orders, where the Flying Lemur fits into the Dermoptera Order, and the Grey-Headed Flying Fox into the Pteropodidae Order.
