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.

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.Barro, Robert; Sala-i-Martin, Xavier (2003). Economic Growth. Cambridge, MA: MIT Press. pp. 375. ISBN 9780262025539. OCLC 2614137. 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. That leapfrogging can arise because an established monopolist has a somewhat reduced incentive to innovate because he is earning rents from the old technology. [4] This is somewhat based on Joseph Schumpeter's notion of ‘gales of creative destruction’. [5] The hypothesis proposes that companies holding monopolies based on incumbent technologies have less incentive to innovate than potential rivals, and therefore they eventually lose their technological leadership role when new radical technological innovations are adopted by new firms which are ready to take the risks. When the radical innovations eventually become the new technological paradigm, the newcomer companies leapfrog ahead of the formerly leading firms.

The concept of environmental leapfrogging also includes a social dimension. The diffusion and application of environmental technologies would not only reduce environmental impacts, but can at the same time contribute to sustainable economic development and the realization of the Millennium Development Goals (MDGs) by promoting greater access to resources and technologies to people who currently have no access. Regarding electricity currently nearly one third of the world population has no access to electricity and another third has only poor access. Reliance on traditional biomass fuels for cooking and heating can have a serious impact on health and the environment. There is not only a direct positive link between sustainable renewable energy technologies and climate change mitigation, but also between clean energy and issues of health, education and gender equity.

Words that rhyme with 'frog'

When tadpoles change into frogs, all the organs of their bodies have to transform to be able to live on land. 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.
