The Egyptian representation of animals made it easier for scientists to accumulate a detail record of large mammals. The scientist gathered the record of large mammals which lived in the Nile Valley 6,000 years ago. A novel study of this record suggests that the extinction of species is usually happens because of the dry climate and an increase in human population. This extermination of species has made the stable.
The report is printed in the journal proceeding of the National Academy of Science (PNAS). The study stated that native annihilation of mammal species gradually weakens the stability of the animal communities. In this report researchers talked merely about Nile Valley.
Justin Yeakel, the author of this study stated that the loss of a single species had a minor effect on the performance of the ecosystem. However, it is only applicable in the presence of numerous other species.
Almost six decades ago, there were 37 species of large bodied mammals in Egypt, but now only eight species are left. The names of the species recorded in artwork, but no longer found in Egypt anymore are lions, wild dogs, elephants and giraffe.
Furthermore, Yeakel stated that the species which was once found in various communities are now quite uncommon. One of the chief things which is pretty evident after the decline of the species is the loss of the ecological stability. There are a number of species of gazelles and other herbivores that are essential since many animals hunt them. Therefore, the loss of one species leads to the extinction of another species.
This new report is grounded on the records collected by zoologist Dale Osborne. Osborne wrote a book “The mammals of Ancient Egypt” which gave a detail picture of the history of animal communities.
