axonomy is generally a complicated topic. There is today
no representation possibility to represent all living beings
correctly. However, the contemporary taxonomic system is the
best what science has to offer Through the centuries, the
arrangement of the tiger changed again and again. Of the division
Linnés up to the system Pococks, the tiger occupied
numerous positions. The following representation announces
the taxonomic nomenclature the tiger, the nominatform as she
is valid at the beginning of 2002 (A.C.):

If one would have to designate scientifically
the tiger (the nominatform) exact, he would come for the following
result although this full representation is demanded rarely:
Animalia Metazoa Eumetazoa Bilateria Deuterostomia
Chordata Vertebrata Tetrapoda Mammalia Eutheria Carnivora
Fissipedia Cynofeloidae Felidae Felinae Pantherini Panthera

Taxonomy is by itself and considerably more
extensively than represented above. Wholes units like theria
(PARK & HASWELL 1897) or tribosphenida (McKENNA in 1975)
were not considered by me since else the expenditure would
escalate to the boundless. There is an "absolut"
complete taxonomy here!
This taxonomy applies of course only to the nominatform.
There is and/or were in total seven tiger kinds. These distinguish
in the case of the taxonomy only in sub-kind, therefore in
the last place that taxment. Newer finding, that the sumatratiger
is an own kind below the Panthera omit I here outside before
yet would plan this change no influence from the classification
into the Panthera and all predecessors step/tiers.
As annotation, I would like to still state some facts over
other large cats before I come to the taxonomic systems. To
the genuine large cats, I would like to only refer to the
leopard of which science knows approximately 25 different
sub-kinds and designated them. Of the bigger cats, the cheetah
is the only one who was not put into the kind Panthera.
The cheetah is a cat kind which parted itself soon from the
Felidae and does not appertain to the scientific "genuine"
cats. The cheetah is in the sub-family (2) Acinonychinae.
This in turn only consists of the kind (1) Acinonyx with the
cheetahs, scientific jubatus, as a kind (1). Summed around
are eight cheetahs degenerate known by the science. Therefore,
it is usually, that the nominatform receives the same sub-kind
name that kind also bears, Acinonyx jubatus jubatus for usual.

The Position of cheetahs to the "genuine" cats
furthermore, is unimportant for my next points . Since one
can not serve in the case of taxonomy of the other large cats
with further special features (!!), too these should be mentioned
at the following no more.

It would be no complete insight into taxonomy
of the tiger if I would not still deal with the historical
process and the different systems of taxonomic representation.
However, some names must be mentioned without fail during
this venture. This would be natural with Linné, and
J. E. Gray, R. I. Pocock, I. Weigel and Th. Haltenorth. However,
it is much too complicated to designate the many other researchers
those made themselves earned around this topic but its incomes
were also very important and in part have existence up to
now.
The animals of the arrangement Carnivora are instead generally
suitable in the best possible way to feed on meat. According
to contemporary opinion which ever saw the world, the Felidae
in itself unite the highest specialized carnivores adapted best.
The tiger as a most powerful and biggest form of the cats is
a sign for this statement. With the family of the Canidae together
(breed of dogs) form the Felidae the ubber family Cynofeloidea
that forms the first group of the rezent carnivores simultaneously.
The second group of these carnivores form the super family Arctoidea,
to the the families of the Procyonidae, Ursidae (bear), Mustelidae
(marten) and Ailuridae (pandas) may appertain. The third and
last Ueber family of the carnivores to which Viverridae (creeping
cats), Protelidae (earth wolves) and Hyaenidae are corresponding
are the Herpestoidea.
There is another a honor progressive division diagram, that
the Felidae puts Feloidea into the Ueber family, and an own
Ueber family grants the Carnoidea, as the name already says.
Also the own Ueber family of the marten animals is a cutting
feature of this concept. However, this could not be correctly
successful.
Linnés "Systena Naturae"
is the approach newer no. first in order to order formally
all ways of life in a scheme. All cats appertain to Linnés
opinion (regardless whether small, averages or huge), that
he described, for the kind Felis. However, the cats enjoy
no special meaning. Linné assigned, included of course
too the cats, carnivore to the arrangement Ferrae all. An
independent family of the cats became only 1821 through J.
E. Gray introduced and Felidae baptized by it.
One many times also speaks of the taxonomic system of the
Felidae. In this way can brasher her works to this honor thought
cover system. Long time are to be reformed in a failed manner
many authors next to it the division the Felidae since they
managed artificial kinds and were not based on nature during
the division and on the degree they formulated welfare families.
A new, in itself conclusive, new division of the cats managed
only R. I. Pocock in 1917. This Pocock's system is up to now
valid and the basis is for the taxonomy pages of my home page.
Except for less changes which Pocock still partially carried
out herself, this system is up to now constant.
Pocock introduced engraving modifications. Among other things,
he divided up the Felidae in three sub-families Pantherinae
(Pantherini), Acinonychinae and Felinae. The Pantherinae close
the biggest forms of the cats, under this natural with the
tigers as a biggest cat, a and are into again two kinds, the
Panthera and the Unica (ounce), subdivided. The cheetah is
the only member of the Acinonychinae and the sub-family of
the Felinae in itself unites all other cats. However, Pocock
did not halt here and in this way, continued that he cut up
the Felinae in 14 kinds. Whitin that 14 genders you can find
cats like the cougar, the lynx and the nebelparder (Neofelis
nebulosa).
A greater change at Pococks basic system were reported by
Haltenorth and Weigel. The lynx was separated by the Felinae
and received an own sub-family with name Lyncinae. Many researchers
considered this fuer a completely random delimitation which
lacks every naturalness. This wants to be one of the reasons
why this change could not also be successful as right.

All older Felidae system have one honor
static design. For this reason, mapping systems more and
more high-powered at newer time are asked. This was above
all necessary since science today more has average available
in order to clarify the degree of affinity of animals. An
thought his here only the possibilities of genetics, those
already discussions about the sumatratiger in the may roll
brought wears.
A central point during the delimitation of the large cats
to the less cat forms is still the construction the hyoid
bone apparatus. For closer information on this anatomical
feature, you should visit the pages via tiger
anatomy. Since 1835 disclosed this feature to Sir Richard
Owen next to lions served it as a delimitation feature.
It is in fact that cutting, which one up to now the foundation
stone is for the kind Panthera.
Despite that famous scientists, as Weigel, Petzsch and
Leyhausen, want to do greater changes to Pococks system
they could not carry out maintain itself against some stubborn
things. In Weigel's system the nebelparder is assigned to
the Pantherinae for example. This division hit Weigel on
account of finding of its teacher Haltenorth that found
a great similarity of the skull of Nebelpardern with that
of the large cats. However, the previous kind Neofelis identified
no hyoid bone apparatus as the large cats, this division
could not be right therefore. It were also assigned the
lynx of Weigel the Felinae what deviation from Pocock a
second great represented.
In the reference to the tiger, an experiment Leyhausens
must also be stated to assign the tiger of the kind Neofelis.
Since one of the most famous researchers of his time was
Leyhausen, this was at first accepted contradiction rid.
However, resistance little by little moved compared to this
division. It however, is up to now in the conversation to
also occasionally describe the tiger as Neofelis tigris.
Such denotation are still to be found frequent above in
all older works.
As last for taxonomy of the tiger, I would
like to still state onto a very interesting high-powered
system which was thought up by Prof. Petzsch. Without closer
in the details go too woolen would like I show an example
of application of this system. At the static ones system
is the division of the cat ways of the American one very
inconsistent continent. By the division of the continent
of eurasia are not to be ordered in a resulted manner own
development directions that logic according to opinion on
Petzsch these cats upright into the taxonomic tree. It makes
more sense to consider these development directions as two
parallel columns be. In such a way, the scientists searched
among the cats for twin pairs. You came at the end, that
the jaguar is the counterpart around leopards of the "old
world" and that it no analogy to the tiger gives. However,
this opinion is also not lasting after Petzsch. He considers
the tiger fuer the counterpart of the jaguar and assign
to the leopard honor the cougar to. With the closer motives
I would like no more to however deal here and today.
As last another a plan to the kind denotation Panthera.
This kind was then still described as Panthera Oken. Oken,
was also a researcher, only employed probably this denotation
as a comprehensive term. However, the name Panthera Oken
is not valid according to the international nomenclature
rules. Other names like that of Leo Brehm or Panthera Tigris
(with big T, that is a difference) had priority. Since however
Panthera Oken had already become a habit as were him the
granted statuses of a "nomen conservandum" and
explained at once all other names for inadmissible. It should
not be changed so important names continuous would read
the former reason.
