If the female is responsive to the male, she raises her tail and the male will follow her. Sometimes the kangaroos will scratch each other’s tails or the male will give the female a back rub before mating. When the female is ready to mate she will arch her tail.

Female kangaroos usually only have one baby kangaroo (called a "joey") at a time. The newborn joey weigh as little as .03 ounces when first born, after which it crawls into its mothers pouch where it will nurse, grow, and develop. They spend a lot of time in their mothers pouch developing. The Red Kangaroo joey will stay in their mothers pouch for about eight months and Grey Kangaroo joeys stay in there for about a year.

Other views on kangaroo origins include the belief of some Australian [[aborigines]] that kangaroos were sung into existence by their ancestors during the "[[Dreamtime]]" <ref>[http://www.painsley.org.uk/RE/signposts/y8/1-1creationandenvironment/c-abor.htm "An Aborigine Creation Story"]</ref> and that kangaroos and the other marsupials evolved from a common marsupial ancestor which lived millions of years ago.<ref>http://www.accessexcellence.org/AE/AEPC/WWC/1995/australia.html</ref>
