Carrying the baby in the pouch is convenient for the female, who may travel many miles for fresh food and water. The youngster stands a greater chance of survival because it does not have to keep up with her. The baby is tucked away, safe from predators.

Kangaroos have a pouch because Australia has a very irregular climate. In eutherian mammals (like people), the developing embryo acts like the ultimate parasite. The baby is calling the shots, taking a huge proportion of the mother's food while it is in the womb, and the parent has no control over that at all. In such circumstances the foetus' requirements in a drought could carry the mother to starvation- which of course would lead to the death of the baby as well.
In Kangaroos the baby is kept in a pouch where the mother can turf it out if things are rough. It sounds callous, but female kangaroos can store sperm in their oviducts and also hold the young at an early stage of development in what is known as embryonic diapause. So even if she has killed her baby out of necessity, if she finds some food, or the drought breaks, she can immediately kick off a production line of joeys, even if she hasn't seen a male for six months. Amazing, eh?

Kangaroo pouches serve as the location where a developing young
kangaroo grows from about the size of a kidney bean to its size when it can
move about on its own.
The kangaroo begins its life as a fertilized egg much as the same way
as humans, but, as mentioned above, when the developing 'fetus'
is the size of about a kidney bean, it migrates, through what is really
a dangerous journey, from its mother's uterus to the pouch where it
continues development. The young kangaroo will mature there, and it
is often a humorous sight to see basically a fully developed small
kangaroo riding in its mother's pouch

What about the pouch of kangaroos?
It acts like a secondary development area for the partially developed Joey. There they stay and feed until developed enough to leave, but do return sometimes.

As per classification of animals all animals with pouch are catagorised as marsupials, Kangaroo fall in this group. Apart from this Australia is probably the only Continents which was cut off from any land mass, before they all got split.

Some animals need extra time to develop OUTSIDE of the mom's body BUT in a protected place. Kangaroos are teeny when they are "born" and make their way up mom's belly to her pouch.
K-bears in Australia have a backwards pouch. The baby is teeny-tiny.

The pouch holds the kangaroos young, as they need to hop off regularly at great speed it makes life much easier ( as their forearms are small and not very strong holding them would be most uncomfortable and they dont have very womanly hips to rest them upon )

Who knows? marsupials all have them. For some reason it worked for them to give birth at what we would consider an extremely early stage and for that baby to go in the pouch. it still works for them.
