"Biologically, human beings haven't changed in 100,000 years - but thanks to our amazing brains we can upgrade ourselves to add capabilities that took other creatures millions of years to evolve. Thanks to this "unnatural" evolution we are already Human 2.0." "In an effort to live longer, become more attractive to the opposite sex, be better able to defend ourselves, make the most of our brains, and repair damaged bodies, we have transformed ourselves." "To do this, we have done many things: created artificial skin in the form of clothing, cloned human organs for transplants, and used nanotechnology to provide support for failing functions in the human body." "Now with a better understanding of these mechanisms of the body, cloning, gene therapy, bionics, and other technologies, the rate at which we're changing is becoming ever faster. This process of upgrading is nothing new. It has been around for millennia, and it raises some provocative questions, such as: What will the future hold for us? Will our drive to upgrade continue to give positive benefits or will it result in the destruction of our humanity? Where is our evolutionary survival heading?" "Sure to cause much debate, Upgrade Me is science journalist Brian Clegg's ambitious account of humanity's need to upgrade."--Jacket.
