Transcript of Evolution of the Giant Panda

By Lexie Greedy 10 Bunjil Evolution of the Giant Panda 8 million years ago
Analysis of fossils found at the edge of the tropical humid forest around the Lufeng Area in Yunan Province of China, showed the giant pandas ancestors lived there. The primal panda (Ailurarctos lufengensis) was like a fat fox. The primal panda became extinct in the late Miocene period. Primal Panda Fossil 3 million years ago
In the early Pleistocene period, a main lineage of the primal panda (Ailuropoda microta) was found in central and south China. It was half the size of the giant panda that we see today and looked like a fat dog. The fossil of this type of panda is named Ailuropoda Mircta. From the fossil teeth of the Ailurpoda Mircta, it is said to have evolved into a species of omnivorous animals which partially feed on bamboos. The Ailuropoda skull (left) compared

the Giant Panda lived. 1 million years ago
Small figured pandas were found and started to extend their living areas to sub-tropical humid forests. Later on, the giant panda further adapted to life in subtropical bamboo woods and their bodies grew bigger and bigger. It is suggested that they grew to such a large size to compensate for their very poor diet of bamboo. 500 - 700 thousand years ago (Pleistocene period)
This was a flourishing age of the giant panda. The fossil of the time Ailuropoda Milanoleuca Wulishansis is only 1/8 smaller than that of the present giant panda. What the panda looked

mountains in China Mid and late Pleistocene period
During this time there were great environmental changes. Large areas of glacier appeared in the Qingling Mountains. This meant that much of the Giant Pandas habitats were destroyed and frozen over. 18 thousand years ago
The amount of Stegodon Sinensis Owen fauna declined, most animals became extinct and only fossils indicated their existence. The giant panda disappeared in the north and their population in the south shrank also. From this moment giant pandas then started to decline permanently. The skulls of Panda's thousands
of years ago are very similar to present
day Panda's 10 thousand years
In the past ten thousand years the development of human civilisation has forced giant pandas to live in high mountains and deep valleys. Today
The population of giant pandas is extremely low and the species is very close to extinction. As groups are isolated from each other, inbreeding occurs causing a loss in genetic diversity. Spain
Panda fossils have been found in Spain by spanish researchers. The fossils have shown this species of bear was smaller than the sun bear which is currently the smallest bear species. The panda-like bear was said to have gone extinct millions of years ago due to receding forests. Hypothesis
During the course of its evolutionary timeline, the panda has not changed greatly. The biggest changes it has undertaken, is its habitat and the size of its body. The information I found from different sources
was very similar as not many fossils of Giant Panda's
have been discovered meaning that a lot of their evolutionary history is unknown.There is still a lot to discover about these amazing creature that have roamed the earth for millions of years. What is yet to be found and what it could possibly open our minds to is truly a remarkable thought. http://kenshin312.wordpress.com/evolution-of-the-giant-panda-and-its-current-status/ http://www.pandasliveon.com/giantpandas/panda-history.html http://www.msnbc.msn.com/id/26036245/ns/technology_and_science-science/t/pandas-evolutions-big-fat-adorable-mistake/ http://bearsoftheworld.net/primal_panda_bears.asp The panda bear has experienced many evolutionary
changes. It size has grown from the size of a fox to its current size. The fossils of the giant panda have mostly been found in China where they have lived for millions of years. Giant panda's have had to deal with different environment changes that have caused their habitats to change. These environment changes causes many pandas to die out, leaving very few members of the species left. Scientists have only recently found fossils of the panda and its evolutionary history is still not completely known. There are still many fossils to find and information to gather to completely understand the evolution of the giant panda.
