Koalas fur holds the key against all the extremities of the weather at the Australian continent. Humans and many animals have a monogastric digestive system as illustrated in Figure 5a and 5b. The enemies of koalas in the north are habitat destruction and fragmentation by urbanisation and climate change. Male Koalas spread their scent marking through trees. Therefore, it is very interesting to explore why female Koalas live more than male Koal. Loss of koala habitat and koala food trees (eucalyptus leaves) is the leading koala threat.

This helps us learn how the genomes of humans and other mammals got so puffed up with junk DNA. Each year hundreds of koalas die because of bushfires, thereby; bringing them on the brink of extinction. This fermentation process releases very little energy and in the case of the Eucalyptus leaves even lesser amount of energy is produced for koalas from the fermentation chamber. In reproductively mature female mammals, an interaction of hormones from the pituitary gland and the ovaries produces a phenomenon known as the estrous cycle. From about 22 to 30 weeks, it begins to feed upon a substance called "pap", which the mother . Koalas in Queensland are smaller, lighter in colour and have less fur than those in New South Wales, Victoria and South Australia.
