 First, consider the lower half of  Figure 5  and regions 1, 2 and 3. While organisms are both Darwinian individuals and living agents, there are two different types of Darwinian individuals that are not living agents: some parts of organisms, such as genes (region 2) and, perhaps more controversially, groups such as colonies of eusocial insects (region 3). For example, honey bee colonies appear to be Darwinian individuals even though they are not literally living agents. Each individual bee within a colony is alive, but as suggested by the discussion of living agency in  section 6,  it is only by invoking the cognitive metaphor that the whole colony itself can be said to be a living agent.
