I am currently working towards a PhD in microbial genetics. Before that I spent a bit over a decade working as a programmer, with most of that time spent writing computer games. I have degrees in Mathematics (MMath), Life Sciences (BSc) and Molecular Genetics (MSc).

comment Why are fruits so large compared to their seeds?
@MarchHo: Okay, fair point. What I mean is that it's not just that they have smaller seeds it's that these seeds are, as you say, totally non-viable.

Just to note, the Cavendish banana, like all other edible bananas doesn't just have small seeds, it is seedless. In fact, all banana plants (of the same variety of banana) are genetic clones of one another produced by vegetative reproduction rather than sexual reproduction.

comment Does DNA have the equivalent of IF-statements, WHILE loops, or function calls? How about GOTO?
Even in parallel programming languages, each statement in executed sequentially. It's just that there are multiple "threads" of execution going at the same time. DNA is neither data nor program. The analogy is totally inaccurate.

I'm not saying that DNA needs proteins to execute its functions; I'm saying DNA is fundamentally unlike computer code.

While your examples are clever I feel the analogy used here (DNA against computer code) is so very poor as to be misleading.

comment Why did life not evolve to use radio?
@DanDascalescu: (1) What do you mean there is no transmitter? Bats create the sound they listen for echoes of and (2) Bats' echolocation works by further evolution of the already-selected-for abilities to hear and make sounds.

comment Why only female mammals have well developed mammary glands?
I addressed your first point in the second paragraph. Male investment is high in humans, it is not in mammals in general and the dimorphism in mammaries did not evolve in humans. As to your second point, it's certainly true that males invest in reproduction to similar levels to females but in the individual offspring the investment is higher in the female.

Incidentally, the XY system is not used in all mammals so there is a slight lack of generality here.

I think this answer, while of decent quality, does not actually address the question the OP is asking. This is the mechanics of how there is a difference not the reasons why there is a difference.

comment Why are some fungi poisonous?
@Anixx: I'm not aware of such a claim and would be interested in a source? Even if it is true I am quite certain that those mushrooms will not be poisonous.

comment In males, why it is difficult to control orgasm?
Both men and women can learn to control orgasm for prolonged periods. It is a reasonably common part of BDSM sexual practices to insist that the 'sub' requests permission before orgasming.

comment When writing about past research should I use the species name they employed or the modern version?
I think you're confusing more than one thing here. Campylobacter fetus is the correct, current, internationally recognised name for the species. Like many species, it has been moved to a different genus than it was originally assigned to. The principle of priority applies when the same species has been identified by different researchers.
