Is it true that there is no absolute morality?

I would aim even lower.  There's no need for a best decision on anything.  Just avoid harming people, and try to help them.  

That's fine, but there's the chance that due to lack of information, you are doing harm in the long run.

I don't think that the benefit of the species is a moral standard to begin with, so, to me, no amount of knowledge as to what benefits the species would be sufficient as a moral fact.  If I possessed full knowledge of the benefit of our species...I may still know nothing with regards to morality.

Morality is one of those funny things-- we all think we have a sense of what it is, but when you examine it under a microscope, it starts getting a lot more squirrely. That's why I'm almost ignostic on objective morality-- I'm pretty sure that for any moral view or goal, we each have a maximally "right" behavior available. So if it's not genetic fitness, and is instead maintaining the most positive hedonic balance or whatever, it's still "out there" somewhere perhaps.
