The local responded "kangaroo", said to mean "I don't know/understand", which Cook then took to be the name of the creature. Unklar ist, in welchem Ausmaß die menschliche Bejagung (Overkill-Hypothese) oder klimatische Faktoren dafür verantwortlich sind – durch die Bindung großer Wassermassen während der Würm-Eiszeit herrschte eine starke Trockenheit.

A common myth about the kangaroo's English name is that it was a Guugu Yimithirr phrase for "I don't know" or "I don't understand". New research has revealed that a kangaroo's tail acts as a third leg rather than just a balancing strut. Die größte Bedrohung der Kängurus ist nach wie vor der Mensch.

Bei niedriger Geschwindigkeit jedoch ist dieser Bewegungsablauf eher ineffizient und energieaufwändig. [47] The genome of a marsupial such as the kangaroo is of great interest to scientists studying comparative genomics, because marsupials are at an ideal degree of evolutionary divergence from humans: mice are too close and have not developed many different functions, while birds are genetically too remote. Australische Farmer sehen in den Tieren eine Bedrohung ihrer Existenz, da sie ihre Felder abfressen, und bekämpfen sie auf verschiedenste Arten.

Living in mobs can provide protection for some of the weaker members of the group. Scientists are interested in the possibility of transferring the bacteria responsible for this process from kangaroos to cattle, since the greenhouse gas effect of methane is 23 times greater than carbon dioxide per molecule.[40]. Im Oberkiefer haben Kängurus insgesamt sechs Schneidezähne, im Unterkiefer nur zwei. At this time, there was a radiation of macropodids characterised by enlarged body size and adaptation to the low quality grass diet with the development of foregut fermentation.

In addition, the mother is able to produce two different kinds of milk simultaneously for the newborn and the older joey still in the pouch. However, most fights are preceded by two males scratching and grooming each other. [24] Species related to the modern grey kangaroos and wallaroos begin to appear in the Pliocene. Die hüpfende Fortbewegung ist bei hoher Geschwindigkeit sehr effizient. [23] One common behavior is nose touching and sniffing, which mostly occurs when an individual joins a group. They also seem to grasp their opponents when they break contact and push them away. During mutual sniffing, if one kangaroo is smaller, it will hold its body closer to the ground and its head will quiver, which serves as a possible form of submission. [33][34] They sometimes regurgitate the vegetation they have eaten, chew it as cud, and then swallow it again for final digestion. [27] The kangaroo performing the sniffing gains much information from smell cues. The reproduction process is very interesting for the Kangaroos. Der Schwanz ist lang, muskulös und meistens behaart, er wird oft als Stütze oder zur Balance benutzt, kann aber nicht als Greifschwanz eingesetzt werden.
