>These scientists essentially created what may have been a new species, that perhaps would have had similar sentience to us and had them terminated after 100 days.

If that is true then these scientists made the right judgment and they should stop with these types of experiments. What are you going to do with these intelligent but still less than human animals? Let them integrate into society and become a source of conflict? We already have enough conflict between humans over trivial matters as it is. If you add an explicit difference between two parties like a different species then conflicts will continue forever until one side is extinct.

If this research succeeds there will be two potential scenarios: Easily controlled monkey slaves doing manual labor or alternatively those monkeys receive extensive genetic engineering because of lack of ethics to outperform us and therefore replace us.

I don't want either.
