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.

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

environment. It is a movement that restores the environment that humans have damaged. Scientists have addressed the idea‚ in "A life of its own" by Michael Specter‚ of using synthetic biology to mend environmental issues. Synthetic biology combines the "elements of engineering‚ chemistry‚ computer science‚ and molecular biology…to assemble the biological tools necessary to redesign the living world" (Specter 364). There are both positive and negative impacts of a synthetic world on the environment movement

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
