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

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

“Radical Evolution” In Joel Garreau’s book “Radical Evolution: The Promise and Peril of Enhancing Our Minds‚ Our Bodies- and What It Means to Be Human” Garreau discusses the concept “singularity” along with views from Vernon Vinge‚ Ray Kurzweil and others. Singularity is this drastic change that will take place during a period of accelerating change in particular with technology. “The Curve implies one of the all-time changes in the rules. Those who study it call it “The Singularity”. (p.67)

Evolution of Letters Nearly all modern alphabets are descended from an alphabet invented 4000 years ago‚ probably by a group of people related to the ancient Hebrews‚ Phoenicians‚ and Canaanites‚ living in what is now the Sinai desert. They got the idea from the Egyptians‚ but used their own simplified pictures to represented consonant sounds. The Phoenicians and others of the region simplified the pictures further and often rotated them‚ but if you use your imagination‚ you can still make out

Evolutionary Concepts Defining Speciation: BSC and Recognition concept Species are produced by individual speciation events‚ so a single species concept can’t be defining all species. Hugh Paterson’s ideas are significant in understanding evolution. Paterson argues that speciation is not an adaptive process‚ but is a result of the adaptation of intricate bonding mechanisms to a new environment (Paterson). The conceptual basis of his research is the Recognition Concept of Species. He argues that
