Orangutan Evolution
Orangutan Evolution
There is evidence to suggest that
orangutans evolved more than 70 million years ago. They are
part of the ape family. Up until about 20 million years ago all
apes were in the same category. It is believed that they
branched off at that point into two distinct groups. The first
is the greater apes which include gorillas, chimpanzees, and
orangutans. They also differentiated in locations around this
time as well.
Today there are only two species of orangutans left in the
world. They are distinct enough due to their location to be
considered separate species. Yet they are still very closely
related genetically. In fact, the two species of orangutans can
breed with each other without any problems. It has only been in
the past 2 million years that the orangutan has taken on the
form that we are familiar with today. It was a slow process
though and one that still has many missing segments to it.
It is believed that approximately 10,000 years ago
orangutans were found in more of a distribution pattern than
today. They are limited to only a few regions of Asia today and
that land continues to be taken from them every day. Some of
the areas where orangutans used to inhabit include China,
Indonesia, and Malaysia.
Based upon the fossils that have been located, it is known
that orangutans extended as far south as Java at one point in
time. These fossils are approximately 40,000 years old. Along
the highlands of Sumatra there are fossils that date to about
35,000 years. What is believed is that in both of these areas
the orangutans were used as a source of meat for the people
living in the areas. However, since the population was
relatively small and the tools not very advanced it isn’t
believed that they were consumed in a large amount.
There is also evidence including cave drawings to indicate
that the use of orangutans as pets occurred in very early
times. These orangutans were likely the beloved pets of cavemen
that lived there. However, there are also indications that some
of them were merely raised by the cavemen until they needed
additional food sources. It was easier to breed them and to
keep them than to have to go back into the forests to find
them.
We do have more evidence about the evolution of orangutans
than many other animals. This is important because it can help
to pave the way for more links of the great apes and even to
humans to be examined. There are people on both sides of it
about the evolution theory that people came from apes. When you
examine the DNA though you can’t deny that they are extremely
similar in about 98% of the genetic coding.
While we do know quite a bit about the evolution of
orangutans, there is still a great deal about them that we
don’t know. Efforts to put together more information has been
put aside for now. With the more pressing issue of if the
orangutans will continue to survive it is understandable that
money and time are being spent on that cause instead.
Hopefully with the right conservation efforts and plenty of
education we can get their numbers back up. Only then will
researchers once again feel comfortable enough to get back to
the theories that remain about their evolution process. These
are amazing animals and they certainly have been able to adapt
to many changes in their environment. Yet they aren’t a match
for the desires of humans. Ironically, it is the choices of
humans that have threatened them and also the choices of humans
that can safe them.
