托福阅读文本：
What unusual or unique biological trait led to the remarkable diversification and unchallenged
success of the ants for ever 50 million years? The answer appears to be that they were the first
group of predatory eusocial insects that both lived and foraged primarily in the soil and in rotting
vegetation on the ground. Eusocial refers to a form of insect society characterized by
specialization of tasks and cooperative care of the young; it is rare among insects. Richly
organized colonies of the land made possible by eusociality enjoy several key advantages over
solitary individuals.
Under most circumstances groups of workers are better able to forage for food and defend the
nest, because they can switch from individual to group response and back again swiftly and
according to need. When a food object or nest intruder is too large for one individual to handle,
nestmates can be quickly assembled by alarm or recruitment signals. Equally important is the fact
that the execution of multiple-step tasks is accomplished in a series-parallel sequence. That is,
individual ants can specialize in particular steps, moving from one object (such as a larva to be fed)
to another (a second larva to be fed). They do not need to carry each task to completion from start
to finish — for example, to check the larva first, then collect the food, then feed the larva. Hence,
if each link in the chain has many workers in attendance, a series directed at any particular object
is less likely to fail. Moreover, ants specializing in particular labor categories typically constitute a
caste specialized by age or body form or both. There has been some documentation of the
superiority in performance and net energetic yield of various castes for their modal tasks, although
careful experimental studies are still relatively few.
What makes ants unusual in the company of eusocial insects is the fact that they are the only
eusocial predators (predators are animals that capture and feed on other animals) occupying the
soil and ground litter. The eusocial termites live in the same places as ants and also have wingless
workers, but they feed almost exclusively on dead vegetation.
