The Kangaroo Had to Have Hopped into Existence!
Those who believe that all living things are the product of millions of years of evolution tell us that living things develop features that aid their survival. They are quick to point out how some unusual feature of a plant or animal aids in its survival. That's why it's noteworthy that evolutionists cannot explain why kangaroos hop.
The kangaroo has several special designs built into it that make hopping its most efficient form of transportation. For example, every time it hits the ground, 70 percent of the kangaroo's downward energy is stored in its tendons to be released for the next hop. By contrast, a running human only stores 20 percent of this energy. Also, kangaroos are designed in such a way that it is actually easier for them to breathe when hopping than when standing still. With each hop, the kangaroo's organs move within its body, pushing air out of its lungs. It uses its muscles only to inhale. Add all these features together and the faster a kangaroo goes, the less energy it uses for the same distance!
If the kangaroo didn't have these special designs, hopping wouldn't be an advantage to it. At the same time, if the kangaroo originally didn't hop, its special design features would be of no value. In other words, the kangaroo is a complete package of special designs that had to come into existence all at the same time … just as it left the hands of a wise Creator.
