And in harvester ants, I divide the tasks of the ants I see just outside the nest into these four categories where an ant is foraging, when it's out along the foraging trail, searching for food or bringing food back.

And one of the most fantastic displays that I remember, or at least visually, was a foraging behavior.

In all hunter gatherer societies today, there's a foraging division of labor between, on the whole, hunting males and gathering females.

In the view of the Panel, this reflects the uncertain fate of birds that might have migrated to alternate foraging locations.

So for example, if I make a mess that the nest maintenance workers have to clean up, then I see fewer ants out foraging.

Here is a graph that he put together showing the percentage of male deaths due to warfare in a number of foraging, or hunting and gathering societies.

And one of the things that we're studying is how natural selection might be acting now to shape this use of interaction patterns this network of interaction patterns to perhaps increase the foraging efficiency of ant colonies.

So that means as their mate is sitting on the nest incubating the eggs, the other one is out there foraging, and the longer they have to stay gone, the worse condition the mate is in when the mate comes back.

The red bars correspond to the likelihood that a man will die at the hands of another man, as opposed to passing away of natural causes, in a variety of foraging societies in the New Guinea Highlands and the Amazon Rainforest.

When foraging in a rural village, they can exercise that intelligence and explore their varied environment. Before they give birth, sows use straw or leaves and twigs to build a comfortable and safe nest in which to nurse their litter.

We're too busy keeping out the giraffes putting the kids on the bus in the morning, getting ourselves to work on time, surviving email overload and shop floor politics, foraging for groceries, throwing together meals, escaping for a couple of precious hours in the evening into prime time TV or TED online, getting from one end of the day to the other, keeping out the giraffes.
