I am not so sure about that one. Your describing the lack of bias or prejudice, not objectivity. The definitions I have seen for objective are a fact that is true regardless of what our opinions are concerning it.
Lets say several hundred or several thousand years ago we asked several scientists what the twinkling light we now call Saturn was.
1. Some claimed it was a sun.
2. Some with a little better equipment said it was one sun with two other suns on either side that were either smaller of farther away that the main star.
3. The best scientist of the day said it was a planet with irregular features on either side he called ears.
However the objective fact is that it is a gas giant (planet) surrounded by rings and moons. To be objective is to not be subjective, subject to what, our opinions?
Now, were those 'scientists' from several thousand years ago fully informed? No! So their viewpoints need not align with objective reality.
You also have your history completely messed up. Before the telescope was invented, the rings of Saturn were completely unknown. So neither 2 nor 3 would have been a viewpoint prior to Galileo using the telescope on Saturn. Also, nobody claimed Saturn to be a 'sun'. They all noted it was a 'planet', i.e, it wandered through the sky. Note: the sun and moon were also considered to be planets then and the Earth was not.
To not be subjective means that the objective is public, not personal.
Not influenced by personal feelings, interpretations, or prejudice; based on facts; unbiased: an objective opinion. 6. intent upon or dealing with things external to the mind rather than with thoughts or feelings, as a person or a book.

So, the views of those scientists above would have been objective (according to your definition): the views were based on the facts as they knew them without prejudice. They were also wrong.
Malum in se
(plural mala in se) is a Latin phrase meaning wrong or evil in itself. The phrase is used to refer to conduct assessed as sinful or inherently wrong by nature, independent of regulations governing the conduct.

There is no roll or relevance concerning biology in the above. On evolution my deciding to kill other humans is just as amoral as whether I walk upright or on all fours. On evolution my deciding to drown a handicapped child is just as amoral as rescuing that same child. Neither correspond to any objective value or duty I have to anyone.
You aren't listening. Morality isn't determined by how we walk, but by how we think and emote. Were are a social species, so we need rules to interact with others of our species. Those rules are morality. Furthermore, the goal of morality is the well-being of humans since it is human morality (not that of wolves or space aliens) that we are discussing.
Even kids know this. When you tell them to do that which contradicts their desires the first thing they ask is "oh yeah, who say". IOW if you can't point to an objective truth why should I be bound by your opinion?
The objective truth is that humans are a social species.
Your merely presuming (actually your merely declaring) that human well-being is the objective criteria for morality. Again this is speciesm, and can only be actualized because we can enforce our own well being upon all other creatures we know of. It is a self serving assumption forced others at the point of a gun which is unrelated to any objective moral values and duties.
The *only* objective moral values and duties are those the are oriented to human well-being.
Wrong. What is good for humans may well be different than what humans want. it isn't the *agreement* of human ity that is important. it is the *well-being* of humanity that is important. And it most certainly isn't the opinion of even a creator that is important.You really really do not understand what objective means in the context of morality. It has nothing to do with the agreement by any or all of humanity. It has to do with it being true or not regardless of human opinion. What your describing is 100% subjective morality.
Multiplying it from one person's opinion to every person's opinion makes it no less an opinion. This is also a perfect example of the fallacy of popularity. Something does not become any more true based on how many people believe it.
I'm not talking about 'popularity'. It may be a very popular thing to take drugs, but it isn't (always) something that promotes well-being. it may be popular to accept religion, but that doesn't mean it promotes well-being.
Again this makes nothing objective. It just describes one of the aspects by which you form your subjective ethical preferences.
Is it an objective thing whether a rule promotes human well-being? Can we determine, for example, whether a policy of genocide promotes the well-being of people? The answer is that, yes, we can. And it doesn't.
I don't expect that a cat or a dog will have a moral sense because they don't have self-consciousness. They are not moral agents. But humans are. And there are some rules of conduct that *objectively* promote human well-being. those rules are the rules of morality.
I hate for you to waste all your time arguing from an incorrect premise. I am going to have to get you to understand what "objective" means in a moral context. Instead of my trying to explain it then giving a short citation to back it up let me quote more exhaustively from well credentialed scholars.
This post is so long there would not be room to do this here I will pick a briefer post to really clarify what objective means in the context of morality. To be continued:
Objectivity means that a fully informed sane person would agree to the result. To have objective morality means that any fully-informed sane person would agree that a given behavior upholds human well-being.
