Tiger Evolution
Tiger Evolution
The earliest found remains of tigers
come from China and they are dated at more than 2 million years
old. These early fossil remains indicate that the tiger was
much smaller then than it is today. However, it is strongly
believed that the tiger is related to the Saber Tooth from
about 35 million years ago. They evolved into some subspecies
about 25 million years ago and that is where the tiger fits
in.
It is believed that the South China Tiger is one that the
various subspecies have all evolved from. This information is
based upon scientific research and DNA testing. Sadly, this
particular tiger is very limited in numbers and many experts
feel it will be extinct in 10 years or less. Hopefully positive
efforts and conservation can prevent that from occurring.
However, genetic profiling also shows that the Sumatran
Tiger is very different from the other species out there. The
theory is that they were isolated from other tigers more than
12 million years ago due to a rise in the sea level. As a
result their genetic profile as a species is more unique that
that of others.
It is believed that the Bengal Tigers moved into the area we
now call India about 12 million years ago as well. That
indicates that something major was going on regarding the
surface area of the Earth. The tigers had to move to new
locations in order to continue surviving. They are protected in
India but poaching continues as does poisoning them by ranchers
that are tired of their livestock being killed.
What is fascinating is that tigers have been able to survive
so much in the past. However, because of the choices of humans
that is becoming more and more difficult for them to do so. If
we don’t work harder to protect these animals then they will
soon be something of the past. We won’t have anything but
fossils to work with in regards to them. We won’t be able to
benefit from them to learn from or their contribution to the
ecosystem. That is all a great deal to think about, but a
burden that should encourage you to take action.
It is hopeful that more questions that we have about the
evolution of tigers will be answered in the future. As new
technology emerges and new fossils are discovered the puzzle
pieces will fit better. New theories will emerge and old ones
will be credited or disproved. There is no denying that the
evolution of tigers has a fascinating story behind it. We just
don’t know what all of the pages of that story have to say to
us yet.
Many researchers are holding out for the day when we find
those fossils that are much older than 2 million years. Then we
can get huge input to what they looked like and how they
evolved to be the cats we know and love today. In the mean time
we can only speculate about what all was roaming the Earth back
then and the actual form that cats had in it.
It is believed that more subspecies of tigers may have
existed at some point. There is still a great deal of
information to uncover about the past for the tiger. One of the
many reasons why we have limited information though is due to
the priority of protecting the tigers we have left from
extinction. The time and money available is best spent helping
to see their numbers increasing rather than allowing them to
become a part of the past as well.
