PART 1: Question 1 Describe the differences between divergent evolution‚ convergent evolution and parallel evolution and provide an example for each type of evolution. Divergent evolution occurs when change from a common ancestral species increases as time passes‚ leading to a speciation event; that is‚ the evolution of two new species. Convergent evolution on the other hand differs from divergent evolution because it is the development of similar features separately in unrelated groups of organisms

land. This change is called evolution. Who founded the theory; what is it and why it happens will all be explained in the following paragraphs. Charles Darwin is the man who is most famously associated with the theory of evolution. In 1859 he published a book a called ‘the Origin of Species’ which explained his theories on evolution. Darwin received lots of criticism and his theories caused much debate when he first mentioned it. This is because his theory of evolution did not match up with religious

capabilities were introduced to support data transmission. However‚ the data rates were generally lower than that supported by dial-up connections. The ITU-R initiative on IMT-2000 (international mobile Telecommunications 2000) paved the way for evolution to 3G. A set of requirements such as a peak data rate of 2 Mb/s and support for vehicular mobility were published under IMT-2000 initiative. Both the GSM and CDMA camps formed their own separate 3G partnership projects (3GPP and 3GPP2‚ respectively)

mammalian evolution towards colonization of land‚ however in some instances this trend has been reversed; there are three large orders of mammals that have separately re-adapted to marine life‚ the Cetacea (whales‚ dolphins and porpoises)‚ the Pinnipedia (seals‚ sea lions and walruses)‚ and the Sirenia (dugongs‚ sea cows and manatees). This “re-adaptation” is most extreme in the cetaceans which have evolved a totally fish-like form‚ masking their true mammalian ancestry (Coffey‚ 1977). The evolution of

The Evolution of Language The study of language is very intriguing once you start looking a little farther into it. I read through many books and sources to help make the history of language a little more clear and found many interesting ideas. I found that something as simple as the way you use your hand could shape the brain‚ language‚ and human culture (The Hand). I also found many sources on human evolution; and digging a bit deeper into this area showed me many thoughts and

Explain the evolution of computer describing the technologies used in different generations. The evolution of computers started way back in the late 1930s. Binary arithmetic is at the core of the computers of all times. History of computers dates back to the invention of a mechanical adding machine in 1642. Abacus‚ an early computing tool‚ invention of logarithm by John Napier and the invention of slide rules by William Oughtred were significant events in the evolution of computers.

Human Evolution Who we are as a species‚ and where we came from; make up the basis of a fantastic story‚ spanning more than 4 million years. The search for the origins of humanity will be a story of bones and the tales they tell. It’s a story that begins in Africa‚ where our ancestors first stood up.Over millions of years they continued to evolve and eventually spread out across the globe. Some species adapted to the changing world‚ while others went extinct. Today only a single species

“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

The changes that occur during a star ’s life are called stellar evolution. The mass of a star determines the ultimate fate of a star. Stars that are more massive burn their fuel quicker and lead shorter lives. Because stars shine‚ they must change. The energy they lose by emitting light must come from the matter of which the star is made. This will lead to a change in its composition. Stars are formed from the material between stars‚ shine until they exhaust their fuel‚ and then die a predictable
