In the micro evolution level. All species evolved through millions of years to finally become the species we see today. They going under nature selections, genetic draft and mutations which makes them totally different from their ancestors. If we have a close look at one specie, for example horses, we would find out how amazing the process is and how artistic the nature is. They were short leg animal who could not run very fast but could turn sharply. As the environment evolved, coevolution makes them grow longer and stronger legs so that they get food at higher places and run faster.
Beside what the nature did to all the living life on earth, people nowadays start to modify animals' genes to make them serve as special functions. As my opinion, i do think this is a faster way to achieve what they want but it somehow does destroy the balance of the nature.
Clone is one of the most popular biotech topics people like to talk about. It is truly amazing when you can 'copy and paste' animals. As people being happily surprised by this technic, they also fear what this technic will bring to the human world. The movie 'Star War' makes people even horrified. Therefore, biotech technic is really a double blade sword.

Evolution is a bioart form in itself that nature instinctively produces to breed and design the best fit organisms to survive, without the manipulation of experimenters. Each life form is carefully structured and uniquely and beautifully pieced together so that each species is a different art piece from another; even each organism in that species is artistically unique through gene composition or mutations that differentiate one from the other. Evolution and natural selection conducts its own genetic modification and engineering that is completely natural, and sometimes even beneficial to the species.
