Koala's live in Australia, and their diet consists of euculiptis leaves. There are not alot of these trees so you can probably predict that they will be extinct. The koala bears need a solution to this problem... and FAST. They start to try new things like other types of leaves, but they can be picky and it is hard to find anything. They soon start deciding on the animals on the land. They decide on small animals like chipmunks. The bigger koala bears can catch them better then the regular koala's. The smaller koala's eventualy die off and the bigger ones reproduce.
Over millions of years they evolve to be 10 feet tall on their hind legs and are eating Kangaroos and other animals. They travel in groups called packs and they hunt together there is a alpha and he is the first to eat.the koala bear now,also called the pamderadis,is looking alot more like the typical brown bear we know today.It acts and is relitive to the size of the common brown bear.Even thought the koala bear is now more like the brown bear it still has some distinctive features like the color of its fur coat.
This change happened because in one area of there main habitat the koala bears had such an overwhelming population that there leaves were baseicly non existent.Because of that change the koalas in that area adapted and started to grow biggger and the bigger koala bears survived because the could catch animals better then resulting in the bigger ones reprodusing more as said in the first paragraph
