“The Evolution of Airplanes” Introduction This year is the 200th birthday of Charles Darwin (1809-1882)‚ the father of evolution. Darwin’s evolution theory proposes that all species of organisms‚ including human beings‚ evolved from common ancestors. There are five main characteristics in his evolution theory. First‚ there are variations among each population. Second‚ organisms compete for limited resources to exist. Third‚ traits of offspring are inherited from their parents. Forth‚ organisms

In 650 AD the Hindus invented a written symbol for zero. Before this no true written calculations could be made‚ making this one of the most essential inventions to help computers. In 830 AD the first mathematics textbook was invented by a man named Mohammed Ibn Musa Abu Djefar. The subject of this textbook he wrote was "Al

Ever wonder how evolution comes to be? How some species win and others lose? Evolution has many different ways of making organisms all better‚ faster‚ and more adept to live. Four big categories of the mechanisms of evolution are natural selection‚ gene flow‚ genetic drift‚ and mutations. The majority of the time‚ nature goes by a trial and error system that can take up many centuries to come up with a change that is beneficial. Natural selection is the process in which nature removes its mistakes

Human evolution is the evolutionary process leading up to the appearance of modern humans. While it began with the last common ancestor of all life‚ the topic usually covers only the evolutionary history of primates‚ in particular the genus Homo‚ and the emergence of Homo sapiens as a distinct species of hominids (or "great apes"). The study of human evolution involves many scientific disciplines‚ including physical anthropology‚ primatology‚ archaeology‚ linguistics‚ evolutionary psychology‚ embryology

The Evolution of Television Introduction Television is one of the most valuable contributions of the scientists in the last century. The world ’s first real television picture was produced by a Scottish inventor called John Logie Baird in 19251. It was nearly a hundred years to the first television appears‚ television has evolved a lot in appearances and functions.

Evolution is the change in the inherited characteristics of biological populations over successive generations. Evolutionary processes give rise to diversity at every level of biological organisation‚ including species‚ individual organisms and molecules such as DNAand proteins.[1]All life on earth is descended from a last universal ancestor that lived approximately 3.8 billion years ago. Repeated speciation and the divergence of life can be inferred from shared sets of biochemical and morphological

Evolution of Life The earth is about 4.54 billion years old and it is evolving throughout its lifetime from a place with volcanoes‚ serve thunderstorms and limited oxygen.

Essay on Evolution There are many mechanisms that lead to evolutionary change. One of the most important mechanism in evolution is natural selection which is the differential success in the reproduction of different phenotypes resulting from the interaction of organisms with their environment. Natural selection occurs when a environment makes a individual adapt to that certain environment by variations that arise by mutation and genetic recombination. Also it favors certain traits in a individual
