comment What is most ancestral: isogamy or anisogamy?
It's not exactly what you're asking, but the recently published "Tree of Sex" might be relevant: treeofsex.org ; nature.com/articles/sdata201415

I'm with you, and tempted to delete my answer.

comment What are the psychodelic effects of (stellar) anise and how many people are affected?
This is interesting, but terrifying. Have you considered the possibility that there may be Japanese Star Anise (Illicium anisatum) adulterating what your girlfriend thinks is edible star anise (Illicium verum)? [Note, using the latin names may help your google searches as well, pointing them towards scientific literature]

comment Eusociality and Natural selection?
Try the 2001 review "Worker reproduction in honey-bees (Apis) and the anarchic syndrome" by Barron and there are also more recent publications.

comment Eusociality and Natural selection?
@Alex it must have been one of the sources I ctd in this question biology.stackexchange.com/questions/5076/… but I'm not sure which.

comment Did spiders respond to light for building webs before artificial light was invented?
Here's a null hypothesis based on perception bias: perhaps spiders build their webs all over, but they're a lot easier for us humans to see when they're built next to lights. Consider, for instance, the days when the dew and light is just right and suddenly the forest seems to be full of spider webs – they were there all along, but just harder to perceive. I'm not saying your observation is wrong, necessarily, just offering a null to compare your observations against.

comment Why are carnivorans more efficient predators than birds or reptiles?
I think the page is not saying that mammals are more efficient predators, but rather more efficient large predators, presumably because of body architecture, life history, scaling, etc.

comment Is greed an evolved trait?
Really nice answer - I think this is a perfect example of a great response to a "I'm not a biologist, but I just wondered..." question.

comment What is this vinca like vine?
Yeah, it's pretty weedy in my garden certainly, where it tries to climb the trees as in the photo.

comment What is this vinca like vine?
I think it must be a climbing Euonymus. Given its status as a horticultural weed, it's possible you'll get a more informative response on the Gardening & Landscaping SE.

comment Is greed an evolved trait?
There's some connection to this question, although of course 'cheating' in social insects and in human societies could be a very different thing (or, perhaps, very similar): biology.stackexchange.com/questions/5076/…

comment Is greed an evolved trait?
@TheLastWord I think that many evolutionary psychologists would disagree with you. I'm not saying that I necessarily would, but there's at least a lot of scientific discussion on the topic.
