Subspecies
No subspecies are recognized. Sometimes the Persian fallow deer Dama
mesopotamica is regarded as a subspecies, but this is not supported by
the available data and is not adopted here. Both taxa are genetically
very distinct (e.g.
Masseti et al. 2008;
Fernandez-Garcia 2012) and it has been suggested before that these two taxa should better be treated as two separate species (e.g.
Agnarsson and May-Collado 2008;
Gilbert et al. 2006;
Pitra et al. 2004;
Randi et al. 2001).
The main argument for the status as two subspecies is the fact that the two
taxa produce fertile offspring in captivity. However, this is true for
many good species that are capable of producing fertile offspring in
captivity, but rarely interbreed under natural conditions. Indeed, the
study by
Fernandez-Garcia 2012 suggests that there has been very little admixture or hybridization between the two taxa; a similar result is presented by
Masseti et al. 2008
who suggest that the two lineages are distinct since ca. 400.000
years. In addition, the two taxa trace from overlapping areas of origin
(see below under Distribution) and therefore have apparently
differentiated in sympatry, a strong argument for species status.
There are also some fossil taxa sometimes classified as subspecies of
the present species (e.g. Dama dama geiselana and Dama dama clactoniana;
see e.g.
Pfeiffer 1998).
However, this concept of fossil subspecies is not compatible with the
concept of extant subspecies employed here throughout Zoographia
Germaniae, and therefore I do not include the fossil taxa here as subspecies.

Some authors combine most deer species including the present species
into a single genus Cervus sensu lato. However, all recent phylogenetic
analyses agree that the Fallow deer form a well differentiated
monophyletic group (e.g.
Agnarsson and May-Collado 2008;
Gilbert et al. 2006).
The exact branching pattern differs between the published phylogenetic
analyses, indicating that the available genetic information is not yet
sufficient to provide stable reconstructions of phylogenetic
interrelationsships between all Cervidae. However, the Dama species are
always a separate group and in most analyses are the sister group to the
"core" Cervus species related to Cervus elaphus. Therefore, their
separation in a separate genus Dama is supported by:
(1) monophyly of Dama in all analyses
(2) recognition of Dama as a separate genus does not render the "core" Cervus paraphyletic.
Therefore, the recognition of Dama as a separate genus appears justified and is also adopted here.

Distribution
Originally distributed in most of the Middle East. However, the species
has been introduced to southern Europe, and the northern-most parts of
Africa by the Phoenicians and the Romans. The Romans also introduced the
species to Central Europe. Today, the species is common throughout most
of Europe, and has also been introduced in North and South America,
South Africa and Australia/New Zealand. The Middle East is also the
original range of the closely related Persian fallow deer Dama
mesopotamica.
Thus, the original ranges of Dama dama and Dama mesopotamica overlap,
indicating that the two taxa have differentiated in sympatry.
