The female proceeds to seat out a crater shaped depression on the top of the ball and to spread her faeces over the surface. When the larvae hatch, they sit in the crater like so many baby birds in the nest. As far as we know, the parental behaviour of Necrophorus is hardwired. Like the complex behaviours of ants, bees and wasps, it is a biological given, almost certainly encoded in the insect's genes. Whether or not you find a baby Necrophorus reaching up to its mum in a manner reminiscent of the behaviour of mammalian young, there is a long tradition, and much evidence, that says human behaviour is different.
Human behaviour is flexible, characterized by freedom from genetic, or other, determination.
If our infinitely more complex behavioural repertoire, our capacity to talk, to think and all that goes with those faculties, were genetically hardwired, then we should have a genome that is much more complex than that of other creatures. But we haven't. In fact, as Sydney Brenner argued, if you are interested in what genes we have, you might as well sequence the puffer fish, because its genome is much more compact than ours. Despite the fact that we have much bigger brains in proportion to body size than any other animal, we do not have that many more genes. The Role of Genes in Human Behavior .
