Kangaroos are endemic to Australia. It is a very cute animal and is popular, but it has one very unusual feature. It means moving while jumping. It looks like a rabbit and behaves very cute, but have you ever wondered why you have to jump? This time, I will also write about the reason and the threatening physical ability of kangaroos. Kangaroo’s jumping power is far beyond human imagination.
Why kangaroos jump
The reason why kangaroos jump will be explained later, but it is due to the historical background. I’m not jumping on a whim. They evolved according to the climate of the land. Of course, by achieving this evolution, there are advantages and disadvantages.

A study at Uppsala University in Sweden reveals the ancestors of kangaroos. Kangaroo fossils have already been discovered in Queensland, Australia, and analysis revealed that they were about 20 million years old. In other words, kangaroos existed 20 million years ago. At the same time, it turned out that the kangaroos at that time were also jumping a little. However, it is speculated that due to climate change, it specialized in jumping. Twenty million years ago, it was a green area, but now it is mostly plains and deserts. The kangaroos traveled longer in search of food as they became desert. The kangaroos that currently live can reach speeds of 70 km / h. They had to travel long distances to find food in the vast land, and their hind legs developed strongly.
In modern kangaroos, the front legs are rarely used in spite of the well-developed hind legs. This is said to be a proof that the kangaroo itself has evolved into an animal specialized in movement. His leg strength has been strengthened, and he has evolved into a creature that is comfortable even on long movements. Today’s kangaroos have evolved into endurance animals that can travel up to 200km a day.
They can’t walk behind
Emu and kangaroos are known as animals that cannot walk behind. It is said that this is only a risk at first glance, but there is a reason for this. Kangaroos have no natural enemies. There are no animals on the Australian continent that pose a threat to kangaroos. There is no reason to go back because of this. “There is only progress”, this is the greatest feature of kangaroos. It is also a symbol of the Royal Australian Navy because it “doesn’t show its back to the enemy.”
Kangaroo’s physical ability
Kangaroos have mostly degenerated front legs, while their hind legs are very well developed. Therefore, it actually has higher physical ability than humans. The jumping power of kangaroos is amazing, and the Eastern Gray Kangaroo, which is said to have strong flying power, can move up to 10m in one jump. Red kangaroos are said to fly 12-13m. And the jump to the top is a marvelous animal that can fly up to 180 cm. The world record for the human long jump is 9.5m by Mike Powell of the United States. It is above humans. Based on the red kangaroo, kangaroos are said to have 1.3-1.4 times more jumping power than humans.
