 The Trick of Magnifying Normal Creatures

The trick of magnifying a normal creature to menacing size is all too common. The giant amoeba is a familar example; monster insects (or whole populations of them) even more so. It might pay an author with this particular urge to ask himself why we don't actually have such creatures around. There is likely to be a good reason, and if he doesn't know it perhaps he should do some research. In the case of both amoeba and insect, the so-called "square-cube" law is the trouble. Things like streng...

 Hamilton's Model

Hamilton's rule is rb - c > 0. Here c is the cost to the giver's fitness (c fewer offspring because of helping), and b is the benefit to the recipient's fitness (offspring gained by the recipient from the help). Here again, "r" is a measure of the relatedness between giver and the receiver [...] Hamilton’s rule says that for unrelated individuals (r = 0) no benefit can overcome the cost of loss of the altruist's fitness (0 - c can't be greater than 0) and aid giving is selected against...

 Parable of the Scientist as Insect

Those who have handled sciences have been either men of experiment or men of dogmas. The men of experiment are like the ant, they only collect and use; the reasoners resemble spiders, who make cobwebs out of their own substance. But the bee takes a middle course: it gathers its material from the flowers of the garden and of the field, but transforms and digests it by a power of its own. Not unlike this is the true business of philosophy; for it neither relies solely or chiefly on the powers o...

 Humans Aren't Especially Smart, It's Just that We Swarm

I prefer sociobiologist E. O. Wilson's view of us as unfortunate tribal carnivores that have acquired intelligence. Our evolution is more like that of social insects; the advances in knowledge and understanding that we prize are more a property of the human nests we call civilization than of its individual members. The nest is always more powerful than a collection of individuals. Who dares disturb the hornet's nest? Small bees easily destroy the huge and powerful but solitary Japanese horne...

Humans are like other social insects. Our power doesn't come from our brains, but our ability to collaborate.
