Scientists used to think that there was only one species of giraffes but they now know that there are four species. Dr. Axel Janke, a
geneticist from the Senckenberg Biodiversity and Climate Research Center, along
with Julian Fennessy from the Giraffe Conservation Foundation in Namibia and
their colleagues tested the DNA of almost two hundred giraffes from across
Africa. They found genetic mutations that were present in some groups of
giraffes, but were lacking in others. Before giraffes were just classified as
Giraffa camelopardalis, but now they will be one of four species: the southern
giraffe, the Masai giraffe, the reticulated giraffe, and the northern giraffe. A
few differences between the giraffes include jagged lines and dark spots on the
Masai giraffe or the five horn structures on the northern giraffe, but most of
them look the same for the most part. According to Dr. Janke, the species might
have diverged from one another about 1.5 million years ago. They do not know why it took so long to figure out that giraffes have four different species, but he thinks it may have something to do with the fact that there are not studied as much as other African wildlife such as lions, elephants, and rhinos. Giraffes are my favorite animal, so when I saw this article, I knew that I had to read it. It is crazy to think that there are now four different giraffe species because they all look more or less the same on the outside. It is shocking that it took so long to find out that there are multiple species of giraffes, but it does make sense if they were not studied as much as other African wildlife.
This article mainly explains how study of genetics can help us learn new things about different species. There are many things that we do not know about animals,humans,bacterias etc. With the use of genetic studies we can learn alot that will help us learn things to better life and society in general.
