I reject that thesis. We are not animals. Our evolutionary history does not dictate right and wrong.

I agree completely that these biases exist. However, to use a programming term, our biases are implementation concerns.
Injustice doesn't somehow become otherwise simply because we are predisposed to it; our innate biases don't provide a valid excuse for inaction in the face of moral imperatives.
We also have hard-wired general memory and reasoning faculties.
"We are not animals."
We are not base animals, to be sure. Neither are we angels of pure logic.
To illustrate with an extreme: If we happened to be hard-wired by evolution to be tremendously predisposed towards genocidal behavior, would that make any acts of genocide we commit morally acceptable behavior?
