Once the data is examined by reasonable people applying the best reasoning skills there will still be no resolution because, by intelligent, we are attempting to make a social statement about our role in nature. But, that is a social problem, not a scientific problem. One we must make as individuals, and as a society. No doubt some future generation will consider us barbaric for using lab rats, but so be it.
Every generation needs somebody to look back on, so they can see their own progress.
