[Animals]My advice to you is not to box a kangaroo because you will see bad results

The kangaroo [2] or the kangaroo [3] or the kangaroo [4] and the combination of kangaroos, kangaroos, and kangaroos (in English: Kangaroo) is the most famous and largest marsupial animal, and it is abundant in Australia. There are about 90 species of kangaroos, the medium type of which is called the waller.[5] And the little wallaby [5] or the little kangaroo, and there is a very small species called the rat-kangaroo. One of the largest and longest species is the red kangaroo, with a height of two meters. It lives in open grassy areas inland in groups or swarms. These swarms graze during the night and rest in the shade during the day.

When the red kangaroo grazes, it walks on all fours, putting its tail on the ground and extending its legs forward. The tail is very important to maintain balance when the kangaroo jumps. Jumping is the way it moves quickly. An adult kangaroo can jump a distance of five meters and pass a barrier of two and a half meters. The hind legs and paws are used for defense, for example when Two males compete or be attacked by farm dogs, and then the kangaroo can cause serious harm to the dogs. The kangaroo is a skilled swimmer and a fast digger, and it often digs in the ground in search of drinking water. Among the smaller wallabies, there are types of thick tails that love lush areas of plants, and rock wallabies that prefer rocky areas. As for the type that lives in zoos, it is usually found in grassy prairies.
The types of rat Alkengro There are eight species. The small one may not exceed 30 cm in length from the tip of its nose to the end of its tail. The kangaroo rat differs from similar kangaroo rats that belong to the family of rodents. It may seem surprising to see a kangaroo on a tree, but this species actually exists, although it seems confused in climbing, relying on its long claws. The indigenous people of Australia have been living on kangaroo hunting for hundreds of years, and it is immortalized in their traditional dances and pictorial art. Today, the kangaroo is Australia's national symbol. Childbirth[edit] The offspring is delayed in kangaroos because of the climate. If the climate has a shortage of water and food, the fertilized egg does not develop, but rather continues in a state of hibernation, even if it rains, it begins to develop, and Carson discovered in 1945. After mating, the young develop inside the mother’s body for a period of 30 or 40 days
The reason is that the fertilized egg remains dormant for some time in the female's uterus before it begins to grow. This is called ((delayed implantation)) and it occurs in some types of deer or hedgehogs. A day or two before giving birth, the mother lies on her back, licks her stomach, and cleans the pouch. The newly born kangaroo baby is very small, its length does not exceed two centimeters, and it weighs no more than 8 grams. Its legs are short, wrinkled, and it clings to the mother's fur. Within three minutes, it crawls out of the birthing tunnel on her stomach, then enters the pouch without any signs of harm. Help and when he is inside he reaches the milk nipple that is there and clings to it with great force until it becomes very difficult to remove him from it and he remains inside the pouch eating and sleeping for 190 days before he comes out for the first time after he has sprouted fur
And after he grows up, he begins to leave the pouch for longer times, but he returns quickly if something frightens him, so he jumps into the pouch with his head first, then turns upside down, and ends with his head and front hands from the pouch, and with the passage of seven months he is able to roam and feed on his own. At danger[edit] If the mother senses danger, she may push her young out of the pouch in order to become lighter in weight and faster in movement, although this may expose the young to certain death, and before the arrival of the white man to Australia, the kangaroo had no enemy except wild dogs (dingos) and vultures that were They rob the young, but when agriculture spread and expanded, the need for grassy pastures for sheep and livestock increased, and fences were put in place to prevent kangaroos from grazing the grass, then rabbits were introduced to Australia and they multiplied while eating grass as well, so the result was that people began to fight kangaroos and rabbits
Evolutionary history of kangaroos [edit] A team of Australian and British scientists has proven that some species of kangaroos have been able, in their evolutionary journey, to re-develop the tops of teeth that were present in one of their ancestors, which existed about 20 million years before them. This is due to the retreat of forests from the sea coast over millions of years, which led to an increase in the abundance of herbs, which forced the kangaroos to eat more herbs to suit the new situation, and this imposed on them the presence of teeth that cut instead of chewing to suit the new diet. In the comment of one of the study’s authors, Aidan Couzens, a PhD candidate in biology from Flinders University, he says: “It has been shown that small changes in the “base” that determine how teeth form in the embryonic stage have allowed some kangaroos to turn the hands of teeth. The evolutionary clock.
It has been shown that the organs that are lost or abandoned by the organism during development can - develop in reverse - to reappear when the organism is in the embryonic stage, and this is the opposite of what was believed in the past. Biologists have often dismissed the idea that evolution can happen backwards, and always dismissed such occurrences. "Some similar features also evolve in some organisms that are not closely related," explains Gavin Prideaux, Associate Professor at Flinders University. The researchers now think that features that were turned off by genes may re-emerge. The re-emergence of these traits was due to changes in climate, habitat and diet. Kangaroos and wallabies were used as a measure of adaptation to climate changes in Australia. “These animals have existed in the region for about 30 million years, and we are finding out more about how primitive forms of them adapted to soft plants in the forests and how their later species adapted to survive in much tougher conditions,” says Associate Professor Prideaux.
