Males use their smell to determine which female kangaroo is sexually available. For some time, however, biologists have suspected that female swamp wallabies take this evolutionary strategy to the next level possibly conceiving during an active pregnancy. In some areas, kangaroos have become desensitized to humans and have developed an addiction to certain foods that would not normally be in their diets. (MJ Smith, DL Hayman and RM Hope, "Observations on the chromosomes and reproductive systems of four macropodine interspecific hybrids" Australian Journal of Zoology 27(6) 959 - 972 (1979)). Macropod reproduction (kangaroo and wallaby) is truly fascinating. The red kangaroo shares the western gray kangaroos habitat. Some government authorised culling and commercial farming of specific kangaroo species occurs in restricted locations. Although the males had testes, they did not produce sperm and some were found to have Y-chromosome abnormalities. Wallabies are plump and stubby animals that rarely grow taller than 2.7 ft. Their feet are short compared to their bodies and their faces are more slender and smaller. Eco-friendly burial alternatives, explained. Unlike female kangaroos, male kangaroos do not have a pouch. ."

This imprints the young on the foster-species. Red-necked wallabies can jump up to 6 feet in the air. Because the dominant male is larger than the other males (called boomers), over many generations, through sexual selection the males have evolved to become considerably larger than the females (called does). They move the hind legs while balancing on the front legs and tail, then move the front legs while balanced on the hind legs, rather like a person walking on crutches. The breeding season of red kangaroos is year-round whereas eastern grey kangaroos breed all year round with a peak in summer. Deer are members of the order Artiodactyla, the even-toed ungulates.
