The scientists who are chasing a small mark through Australian rainforest from a distance say, may have found an idea of the mystery of the reason for her older older cousins instead of walking.
Researchers from the University of Flinders in Australia said on Thursday, but why is it still a mystery, that the Kangaroo and close related grabs are the only big animals that jump in a straight position on the legs.
They believe that the answer may lie with Kangaroo the small mice, which is a bush weighing the same loaf of bread.
Musky Rat-Kangaroos is a long predecessor for the largest kangaroo that wanders in remote areas.
Researcher Amy Chirin said that Ratangaros in Mski-called their strong smell-was the only members of the “Macropodoid” family that did not jump.
“Musky Rat-Kangaroo provides an insight into how the distinctive movement of movement in Australia has evolved,” she said.
Scientists tracked creatures, also known as “musk”, through tropical forests in the north Queensland.
Note that the creatures move in a “specific” movement – moving with their back legs while their front horizon remained on the ground.
The researchers said he suggested a kind of medium point in the evolutionary journey of walking in all four to move on two.
“These results refer to a possible path of how bilateral movement in Kangaroo is developing,” said Peter Bishop, a biologist at Harvard University, who participated in the work.
He said: “Perhaps it started with a predecessor moved in four like the other shepherd, then an animal that limits like musk, and finally developed into the iconic kangaroo that we see in Australia today.”

The researchers said that the kangaroo and the papa are the only types of jumping are heavier than 5 kg.
Some types of small rodents are also a jump.
The researchers said they hope to find fossils of old pods to better understand the development of kangaroo in the modern era.
Their results were published on Thursday in the Journal of Australian Mammals, which was reviewed by the peer.
