I am a computational biologist with a background in biology, not computers. My PhD work was on gene prediction and comparative genomics but my current research is in systems biology, specifically protein-protein interaction networks.

comment Do humans have enough biological differences to be grouped into races or subspecies?
@JackAidley the statement is one I remember from university. Anecdotal evidence like that presented in my answer seems to confirm it and I was tought it years ago. I'll see if I can find a proper reference but it certainly looks to me like we have far far less variation than other species.

comment Do humans have enough biological differences to be grouped into races or subspecies?
@JackAidley birds of paradise are "natural" as far as that goes. In any case, the point is moot, whether the observed variation has been affected by humans or not, it is clear that the human species shows relatively little variation compared to what can be seen in others.

@Herman you're very welcome, if this answers your question, remember to mark it as accepted so the question can be marked as solved.

comment What is the smallest oligocelluar organism?
@har-wradim hello and welcome to the site. There is no such thing as "the correct answer" on the stackexchange network, the OP chooses to accept whichever answer suits them and that answer is, by definition, the "best". It may be wrong or incomplete but if the OP feels it answers their question then that's that. As for dicty, the cool thing is that it exists and can live as both a single cell and as a multicellular aggregate. The worm cannot and the zygote is an "unfinished" animal, they are completely different.

@draks... thanks for the accept but there are probably more extreme examples.

comment What is the smallest oligocelluar organism?
@Chris well yes but dicty cell counts go from 1 to 100.000 while the worm is always at 956. The interesting part is that dicty exists as a single celled organism as well.

comment Effects of smoking tobacco compared to inhaling other smoke
@Oreotrephes the point is that if you ingest the same quantities of any of these types of smoke, they will cause serious health issues. Of the three, I expect cigarette smoke to be the least noxious.

comment Effects of smoking tobacco compared to inhaling other smoke
Umm, not at all? What makes you think tobacco smoke is more dangerous? If anything, I would expect tobacco smoke to be the least dangerous of the three.
