There are many dangerous animals that can harm a human. The most obvious ones are the larger ones such as lions and tigers. However, smaller animals such as stray dogs can also be dangerous.
The animals themselves are not likely dangerous. However, the science of creating them is debatable. Some feel that these animals will help us find treatments or cures for cancers. Some feel that we should not genetically alter animals at all for any reason. Some feel very strongly that no animal, transgenic or otherwise, should be tested on, that it is cruel, and some fear the possibility of this science being unethically used on humans.
