Animal cloning is an investment that should be refused. Scientists around the world have been trying to perfect the process of cloning animals for decades. Any problems that could arise in completing the cloning process before the clone has a DNA sequence capable of bringing a creature to life. The large number of clones that never reach adulthood is a waste of technology, time and funding. Cloning to save endangered species seems like a fantastic idea, but in reality, the technology is not enough to meet these demands. Researchers are going above and beyond the normal when it comes to the DNA used to attempt cloning. Two contributors to cloning discovered they could harvest sperm, umbilical cord and blood from road victims which could be frozen and preserved. The Brazilian Agricultural Research Society and the Brasilia Zoological Garden collected more than 420 samples from various animals. Countries seem to be engaged against each other in a race for scientific evolution. Just like countries involved in the space race, countries are competing to be the first to successfully clone an animal. The first successfully cloned animal was the leopard frog in the 1950s. The Lankenau Hospital Research Institute successfully cloned a frog through a process called nuclear transfer. Robert Briggs and Thomas King cloned frogs by extracting the nuclei from empty eggs, then extracting the nuclei from frog embryos and replacing them with the nuclei from empty eggs. . Scotland showed the world that they were a force to be reckoned with. They introduced the world to Dolly, the first Finn-Dorset sheep to be cloned. With over 300 attempts at procreation, only 30 embryos have been created. Of these only 30...... middle of paper...... end in failures. The few people who take the first step in nuclear transfer have difficulty developing. Cloning is a great idea, but given the lack of technology needed to make it an effective scientific tool, it should not be a priority. Scientists should devote their time and energy to understanding the reasons for the disappearing animal population instead of trying to do more in unnatural ways. Although it may be more accepted than cloning humans, it is still a topic that people are quick to avoid.
