  Homo habilis and Homo erectus:...

  The evolutionary path from the original primates to modern man is a long one and has taken many twists and turns, but naturally, as the fossil record grows, scientists gain a more complete understanding of our own mental and physical history in terms of genetics and anatomy. However, the correct order and relationships of the various specimen types are difficult to pin down. Many representative samples have been found in such minute amounts as to not preclude anomalies. They have been discovered in various stages of wear. Modern features did not occur simultaneously or uniformly, taking millions of years to become manifest in later types. Up to the present day’s Homo sapiens, examples of the main types have been hybrids of older and more modern features. 
  	One of the earliest species of the genus Homo to be discovered is Homo habilis, which basically means “handy man.” The name comes from the belief at the time of its discovery that this species was the first to start using stone tools. The first fossils to be uncovered in Olduvai Gorge were from the same stratigraphic layer as simple stone tools. Fossils of the crania and postcranial skeleton for this species have been found in both eastern and southern Africa and date to around 2.5–1.6 million years ago.  
  	Given the gradual changes that take place in evolution, Homo habilis shares a number of characteristics that are similar to the genus Australopithecus, such as in the postcranial elements. That said, the size and shape of the Homo habilis skull are markedly different. The size of the brain is much larger relative to the size of the body, being around 680 cc. In order to house a larger brain, the skull features a more vertical frontal bone, creating a more vertical forehead. The brow ridges that sit on the lower portion of the frontal bone are also reduced in size.

  Genomic Politics - How the...

  The emergence of genomic science in the last quarter century has revolutionized medicine, the justice system, and our understanding of who we are. We use genomics to determine guilt and exonerate the falsely convicted; devise new  
  medicines; test embryos; and discover our ethnic and national roots. One might think that, given these advances, most would favor the availability of genomic tools. Yet as Jennifer Hochschild explains in Genomic Politics, the uses of genomic  
  science are both politically charged and hotly contested. After all, genomics might result in bioterrorism, a demand for “designer babies,” or a revival of racial biology. 
   
  Political divisions around genomics do not follow the usual left-right ideological patterns that dominate most of American politics. Through four controversial innovations resulting from genomic science—medicines for heart disease  
  approved for use by only African-Americans, on the grounds of genetic distinctiveness; use of DNA evidence in the criminal justice system; the search for one’s roots through genetic ancestry; and the use of genetic tests in prenatal  
  exams—Hochschild reveals how the phenomenon is polarizing America in novel ways. Advocates of genomic science argue that these applications will make life better, while opponents point out the potential for misuse—from racial profiling  
  to “selecting out” fetuses that gene tests show to have conditions like Down syndrome. 
   
  Hochschild’s central message is that the divide hinges on answers to two questions: How significant are genetic factors in explaining human traits and behaviors? And what is the right balance between risk acceptance and risk  
  avoidance for a society grappling with innovations arising from genomic science? Experts differ among themselves about who should make decisions about governing genomics’ uses, and Americans as a whole trust almost no one to do so.  
  A deeply researched and original analysis of the politics surrounding one of the signal issues of our times, this is essential reading for anyone interested in how the genetics revolution is shaping society.

  There, over seventy thousand Southern troops waged a dogged, bloody battle against over ninety thousand Union soldiers in the fields and on the boulder-strewn heights surrounding the town.
