A life cycle is the changes an animal goes through in its life from a baby to an adult. Life cycles go in circles and keep repeating from one generation to the next. Frogs are amphibianswhich means they can live on land and in water. They go through many stages in their life: Animals like frogs and butterflies go through a process called metamorphosis, they change into something completely different. Caterpillars turn into butterflies and tadpoles turn into frogs.

Leapfrog democracies can refer to countries that have huge developments that more typically advanced countries might only have much later.

The frog's tail completely disappears and it starts to eat insects. It takes 2-4 years to become a fully grown adult. As it grows it sheds its skin. A frog's skin must never dry out otherwise it will die. To prevent this from happening, its skin produces mucus. This is why frogs often feel slimy. When an egg hatches, out pops a tadpole (or polliwog). Tadpoles look more like fish than frogs. They do not have any arms or legs. They have long tails and gills to breathe underwater.

In consequence, when a radical innovation occurs, it does not initially seem to be an improvement for leading nations, given their extensive experience with older technologies. Lagging nations have less experience; the new technique allows them to use their lower wages to enter the market. If the new technique proves more productive than the old, leapfrogging of leadership occurs. During this stage, the tadpole doesn’t need to eat because it uses the nutrients stored in its tail as food. When just a little stub of a tail is left, it becomes a young frog and hops out of the water onto land. Brezis, E. S.; P. Krugman (1997). Technology and Life Cycle of Cities. Journal of Economic Growth. p.2: 369–383. Frogs can see forwards, sideways and upwards all at the same time. They never close their eyes, even when they sleep. More recently the concept of leapfrogging is being used in the context of sustainable development for developing countries as a theory of development which may accelerate development by skipping inferior, less efficient, more expensive or more polluting technologies and industries and move directly to more advanced ones.The adoption of solar energy technologies in developing countries are examples of where countries do not repeat the mistakes of highly industrialized countries in creating an energy infrastructure based on fossil fuels, but "jump" directly into the Solar Age.

In the field of industrial organization (IO), the main work on leapfrogging was developed by Fudenberg, Gilbert, Stiglitz and Tirole [3] (1983). In their article, they analyze under which conditions a new entrant can leapfrog an established firm.

The mobile phone is an example of a “leapfrog” technology: it has enabled developing countries to skip the fixed-line technology of the 20th century and move straight to the mobile technology of the 21st. It is proposed that through leapfrogging developing countries can avoid environmentally harmful stages of development and do not need to follow the polluting development trajectory of industrialized countries.
