The life sciences have almost all the answers to life's questions. Geneticists are now able to produce almost any organism in the laboratory. And it is therefore possible to bring extinct species back to life. Even a small spark of DNA is enough. But - does that make sense? Does science have to do everything just because it can? The basic questions of man and science as an entertaining and inspiring reading experience. Never before in history did man know more about the blueprint of life in general and the individual genetic equipment of individuals and species, called genome, in particular. Humans know so much about it and have developed biotechnology to the point where they can soar godlike to become creators of new species or bring vanished species back to life. Britt Wray creates a chronology of genetic findings, amuses with anecdotes of the associated world views and ultimately asks the question of all questions in an entertaining way: Do we have to, just because we can?
