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

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. The beginning of the life of earth is occurred due to a process that has set a sequence most practical events towards the foundation of where life actually formed so many years ago. The chemical evolution practical process created inorganic molecules to form organic molecules. Slowly this process of evolution created the foundation

to survive and reproduce in its environment. Eventually‚ a population may accumulate enough change that it constitutes a new species. In modern terms‚ we can define evolution as a change over time in the genetic composition of a population. Evolution also refers to the gradual appearance of all biological diversity. Evolution is such a fundamental concept that its study is relevant to biology at every level‚ from molecules to ecosystems. Evolutionary perspectives continue to transform medicine

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

concept of eugenics were widely discussed as knowledge about genetics advanced significantly. Endeavors such as the Human Genome Project made the effective modification of the human species seem possible again (as did Darwin’s initial theory of evolution in the 1860s‚ along with the rediscovery of Mendel’s laws in the early 20th century). The difference at the beginning of the 21st century was the guarded attitude towards eugenics‚ which had become a watchword to be feared rather than embraced.

The evolution of money: an outline of six stages I. From tradable utilities to a generalized medium of exchange accepted as the final payment‚ carrying value over time‚ and used to calculate the equivalence in exchanges… This transition seems logical and unavoidable from the present day perspective‚ but its historical origin remains disputed. A common explanation projects the present day assessment of the logical necessity of introducing a generalized medium of exchange on the past‚ which is a
