I'm looking for a term to refer to an alien species that may evolve differently and have some unique and radical features, but still shares some of the most basic features of earth species. I'm looking for a certain degree of specificity for scientifically accurate discussions.
The most obvious term I'm sure anyone would think of is 'humanoid', but this is far too restrictive. The odds of any alien species evolving to look so human as to be considered 'humanoid' is quite unlikely. Actually the odds of an 'earth-like' species is unlikely too, but still I want a word that leaves open a much large category of species. What I want to exclude with such a word is species that are so utterly alien as to be difficult to grasp for humans at all. Thus I want to refer to species that could be vastly different, but imply at least enough similarity to something from earth to be comprehended by humans.
At a minimum this means carbon-based, but carbon-based is still a very wide window. I'd like to imply some aspects shared by most earth species likely exist, not necessarily requiring all of them. Aspects like multi-cellular bodies with specialized organs, possessing of genetics encoded in some DNA-like manner, Some form of genetic exchange like sexual-reproduction (not requiring traditional male and female), brain-like structure for thinking and driving decision-making (not necessarily sapience or high intellect) etc. Put another way, anything that could realistically be seen evolving from creatures that were very similar to earth's primitive early multi-cellular organisms, even if that evolution went in a very different fashion from earth.
Is there any good word or phrase to communicate this concept beyond earth-like. The phrase earth-like I fear may be a little too restrictive itself, implying perhaps too close a similarity to current living earth creatures and ecosystems and thus not leaving open a little more room for novelty in creature design while keeping to the basic structure.
