The Evolution of Whales “Their tongues alone can weigh as much as an elephant and their hearts as much as a car.” The animal called whales what are the largest‚ intelligent and aquatic mammals. However‚ whales were not the aquatic animals at the beginning. After thousands of years of evolution‚ since changes in the terrestrial environment and the demand for food‚ the whales become appearance like a graceful arc from the four limbs. We have to imagine that what happened in the past thousand years

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

Evolution of Management The evolution of management can be divided into three distinct era’s. The Pre-Classical Era‚ Classical era and Neo-classical era. Pre-Classical Era From the Biblical times we find monarchies of the time use some form of management to lord over the great kingdoms such as the Egyptians who used hierarchy management to build the pyramids‚ Moses leading the Israelites through the desert to the promised land and King David when he was in charge of the kingdom of Israel. In

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

Hominid Evolution The evolution of hominids has been and still is a heated topic of debate. Many scientists debate over which species can be classified as “human”. The root "hominid" refers to members of the family of humans‚ Hominidae‚ which consists of all species on our side of the last common ancestor of humans and living apes. The time split between humans and living apes used to be thought of fifteen to twenty millions of years ago‚ but now the time period has shifted to around five

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

COMPUTERS The evolution of electronic computers over a period of time can be traced effectively dividing this period into various generations. Each generation is characterized by a major technological development that fundamentally changed the way computers operated. These helped to develop smaller‚ cheaper‚ powerful‚ efficient and reliable devices. Today‚ life has become indispensable without a computer. You find computerization in almost every sphere and industry. Computer evolution has been a fascinating

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
