  In a recent study in 2015 the scientists found remains of biotic life in a few historic rocks, Western Australia, which dated back to 4.1 billion years ago and on July, 2016 the scientists confirmed about 355 genes which were from LUCA of all the living organisms on Earth. 
  Formation, change and loss of species through the evolutionary antiquity of life on Earth are validated by common sets of biochemical and morphological traits, plus shared DNA sequences. These common individualities are like species which share a recent common ancestor and can be used to rebuild a biological tree of life centered on radical connection with the help of fossils and species which still exist. The records from fossils comprise of progress from a biogenic graphite to microbial mat fossils to multicellular organisms. The prevailing arrays of biodiversity have been designed by extinction and speciation. Almost 99% of species which have roamed planet Earth are expected to be extinct. There have been about 10 to 14 million variety of species on Earth and 1.2 million only have been documented. 
  Charles Darwin in the middle of the 19th century had verbalized a scientific theory of evolution by natural selection; his work became famous through this published book ‘On the Origin of Species’(1859). When more offspring are produced which can actually survive is termed as evolution by natural selection; there are three main facts about populacesBehaviors differ among personages with respect to physiology, morphology and behavior.Various behaviors convene diverse rates of endurance and reproduction.Behaviors and traits can be passed down to generations. 
  Therefore in sequential generations members of a certain populace are substituted by offspring of parents better adjusted to endure and breed in the biophysical atmosphere in which natural selection happens. The quality where the procedure of natural selection builds and conserves qualities which are fit for the practical parts they perform is teleonomy. Sexual and natural selection are the only identified source of adaptation but are not the only reason of evolution. Mutation, gene migration and genetic drift are other non-adaptive procedures of evolution. 
  The significance of natural selection as a reason of evolution has been recognized into other disciplines of biology. Earlier detained thoughts of evolution like evolutionism, asorthogenesis and other principles on intrinsic progress contained by the largest-scale drifts in evolution became outdated scientific philosophies. By founding and analyzing postulates, creating mathematical models of theoretical biology and biological philosophies, using observational data and executing experiments in laboratory and field the scientists continue to study various traits of evolutionary biology.

  Faithful Presence - The Promise...

  Two-term governor of Tennessee Bill Haslam reveals how faith--too often divisive and contentious--can be a redemptive and unifying presence in the public square. 
  As a former mayor and governor, Bill Haslam has long been at the center of politics and policy on local, state, and federal levels. And he has consistently been guided by his faith, which influenced his actions on issues ranging from capital punishment to pardons, health care to abortion, welfare to free college tuition. Yet the place of faith in public life has been hotly debated since our nation's founding, and the relationship of church and state remains contentious to this day--and for good reason. Too often, Bill Haslam argues, Christians end up shaping their faith to fit their politics rather than forming their politics to their faith. They seem to forget their calling is to be used by God in service of others rather than to use God to reach their own desires and ends. 
  Faithful Presence calls for a different way. Drawing upon his years of public service, Haslam casts a remarkable vision for the redemptive role of faith in politics while examining some of the most complex issues of our time, including:partisanship in our divided era;the most essential character trait for a public servant;how we cannot escape "legislating morality";the answer to perpetual outrage; andhow to think about the separation of church and state. 
    
  For Christians ready to be salt and light, as well as for those of a different faith or no faith at all, Faithful Presence argues that faith can be a redemptive, healing presence in the public square--as it must be, if our nation is to flourish.

  While the fight over gay marriage has been bitterly contested and debated for much of the 21st century, it’s still somewhat difficult to believe that just 50 years ago, homosexual activity was illegal in nearly every state in America. Homosexuals faced discrimination that surpassed that of even African-Americans or suspected Communists, and their lifestyles were so taboo that they were typically considered to be a security risk because it would be so easy for someone who wished to harm the country to blackmail them. In 1950, a Senate Subcommittee on Investigations reported, “In further considering the general suitability of perverts as Government employees, it is generally believed that those who engage in overt acts of perversion lack the emotional stability of normal persons. In addition there is an abundance of evidence to sustain the conclusion that indulgence in acts of sex perversion weakens the moral fiber of an individual to a degree that he is not suitable for a position of responsibility. Most of the authorities agree and our investigation has shown that the presence of a sex pervert in a Government agency tends to have a corrosive influence upon his fellow employees. These perverts will frequently attempt to entice normal individuals to engage in perverted practices. This is particularly true in the case of young and impressionable people who might come under the influence of a pervert. Government officials have the responsibility of keeping this type of corrosive influence out of the agencies under their control. It is particularly important that the thousands of young men and women who are brought into Federal jobs not be subjected to that type of influence while in the service of the Government. One homosexual can pollute a Government office.” Indeed, in the decades that followed, the FBI kept lists of known homosexuals, and law enforcement agencies regularly raided known gay bars and other similar establishments.

  The Search for Reagan - The...

  Never before has anyone explored the mind, soul, and heart of Ronald Reagan. The Search for Reagan explores the challenges and controversies in Reagan's life and how he successfully dealt with each, depicting a man who was never as conservative as some conservatives wanted him to be, but rather as conservative as he was comfortable being—a man who wanted to win on his own terms and integrity. 
   
   
   
  Ronald Reagan was a singularly unique man and conservative who championed a wildly successful revolution—leading to more freedom and less government for the American people and to the fall of communism, while boosting American morale. He was the first president in many years who believed optimism from the Oval Office had a direct bearing on the affairs of the nation. As a consequence, he left office more popular than when he entered, with a whopping 73 percent approval. He understood that American conservatism was based upon the individual and not the group. In his presidency, he solved the mystery of high inflation that had bedeviled his predecessor, high interest rates, and high gas prices. He created over twenty million new jobs, and the number of American millionaires grew from 4,414 to 34,944. He is considered by most historians to be one of our four greatest presidents, along with George Washington, Abraham Lincoln, and Franklin Roosevelt.
