In part this is arguing over a definition of nature.
You're going for the obvious "We are part of nature because nature created us and we work within the system." while they're going for the idea of it being more strictly influenced by evolutionary change which we have the ability to 'escape' (escape in the sense that we can go farther than an animal can due to being able to design larger systems without having each step useful).
The definition of "we are of Nature" is essentially "we are of Physics". This is true, but its not really useful.
On your morality lines:
Morality is a personal concept in people, but it is influenced by society and the people they interact with. There doesn't have to be some objective right/wrong, and so people can say that the scientists were being immoral (according to the person's own moral ideas).
The scientists may very well believe they were being moral, or perhaps they didn't think about it (people do that!)
> that our nature-created brains have led us to create?
Well, as stated before, morality isn't the same between humans. There's no objective authority that decides X is right or Y is wrong, simply social/cultural influences throughout the world.
You could view morality as a way that you think the world/people should behave to maximize some value you hold. Perhaps you value sentient life, and so you hold self-sacrifice to save a dozen people to be a moral good as it continues more sentient life.

Worth remembering that it's also not the case that every person has different morality, and everyone's moral values are uniformly distributed across the space of possible values.
No, the moral values of humans are all very strongly correlated, both within and across societies. We spend a lot of time bikeshedding the details, but we essentially have a shared sense of what's right and wrong.
(I hypothesize it's because we all have the same brain architecture - the basic moral sense is encoded in firmware, and through culture we adapt it to fit the environments and societies we live in.)
I would question your point, "that moral values [...] are very strongly correlated [...] across societies".
My favourite example is the Aztecs society.
Moral values were completly different.
Sparta is another example. The Nazi regime in Germany too. Slavery in the US. I could keep going for another hour.
Moral values are highly dependent on you environmental influences.
Nevertheless you are totaly correct, that the majority of people in a single society shares similair views on moral rules.
