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?

"The most controversial story I’ve ever written. Starts with the baby-eating aliens and moves on from there."
This statement makes no sense. Associating sex with non-sexual things is the definition of sexualization.
And I know why advertisers do it, it's not rocket surgery to figure it out. Their motivation doesn't change the fact that the action itself objectifies and degrades women (and to a lesser extent, men).
Watch an advertiser sell SUVs to women: they have a big, hulking, strong look and are advertised as serving and protecting the kids. That is the masculine face of advertising.
You quote me stating that men are sexualized, and respond by explaining how men are sexualized? What's your point?
Look, men get to use trillions of sperm cells, which means evolution has hard-wired their brains to be magnetically attracted to anything feminine. Advertising uses this not because it is "sexualized", but because men will buy toxic waste by the barrel if you draw nice titties on it.
Women only get to use a dozen or so egg cells, and each one is very risky and resource intensive, which means evolution has hard-wired their brains to be an always-on filter for genetic quality in prospective mates. This is naturally uncomfortable, and has been since before their monkey girl ancestors came down out of the trees.
"Yes, men are sexualized as well, but not to anywhere near the same degree, ..."
Watch an advertiser sell SUVs to women: they have a big, hulking, strong look and are advertised as serving and protecting the kids. That is the masculine face of advertising. (The latest American Subaru ads have it both ways, showing the kids growing up in the vehicle, ending with a cute teenage girl getting out of a car with a ... what is that thing on the hood? ... oh yes, the air port for the turbocharger.)
