comment What is the mass of a pigeon tail feather?
Heh, nothing like the old fashioned empirical approach. I would expect the feather to orient itself with the pointy bit downwards though, it should be relatively standard.

An African or European pigeon?

comment Consequence of Plants as Incomplete Protein Source
@Roland I admit I'm biased since I did my PhD on selenoproteins but it's not that rare. There are 22-25 proteins (depending on how you count them) in the human genome and some animals have many more. They are also essential, those animals that have them can't really survive without them. But yes, I know I'm being pedantic, it's just that it's my field and everyone forgets about poor Sec :)

comment Consequence of Plants as Incomplete Protein Source
I changed the 20 to 21 amino acids since most species also code for selenocysteine.

Selenocysteine, the 21st amino acid is present in all animals (except some insects) and many bacteria. Pyrrolysine, the 22nd amino acid is less common but Sec should be counted.

comment Are trees the only source of large amounts of oxygen?
@AliceD in terms of biomass, I'm pretty sure they represent a very small fraction when compared to photosynthesizing algae and phytoplankton as you point out in your answer. Let alone the grasses. Individual trees are big, yes, but there are not that may of them. In any case, 1) I only mentioned the plant population, not biomass and 2) only a very small part of a tree's biomass is actually photosynthesizing so biomass is not really relevant anyway.

Why trees? They represent a very small part of the plant population of the planet. They just happen to be big.

comment How do I find the number of child terms associated with a specific GO term?
@Wolgast different ontology versions presumably. Or a completely different SQL schema. The ontology files are not static, They change quite a bit and quite often. What you need is the number found in the specific ontology file you happen to be using. Don't assume that different online versions will give you the same result.

Does it need to be done using QuickGO? Would you be open to downloading the ontology .obo file and parsing it? Do you only want direct child terms or all descendent terms (children, grandchildren etc)?

comment Load specific sequences in with BioSeqIO
By the way, you might be interested in my retrieveseqs.pl script. You could use that to extract the sequence you want and then run your script on it. Alternatively, use fastaindex and fastafetch from the exonerate suite.

This would be on topic on Stack Overflow. You can also ask on biostars.org, a site dedicated to bioinformatics.

comment Are there any culinary fruits that are not botanically fruits or accessory fruits?
I think this would be better suited to Seasoned Advice (though I'm not sure about that site's scope, you should check first). You're not really asking anything biological here, you're asking about misnomers that chefs might be using.

I'm voting to close this question as off-topic because it's not about biology but about what chefs consider a fruit.

comment Are there examples of now-living species where one is descended from the other?
Very nice breakdown, +1. One nitpick, however: the unit of "evolvedness", if such a thing could be said to exist, would not be years but generations. A bacterial species is way more "evolved" than a mammal since they've had several orders of magnitude more generations in which to evolve. While I agree that saying "X is more evolved than Y" is nonsensical, if you do choose to make such a statement, you need to think in terms of generations and not time. Time is irrelevant, it is only the number of generations that counts.
