Question

Each of the following groups except one has examples of eusociality. Which is the exception?

1) termites (Isoptera)
2) ants, bees, and wasps (Hymenoptera)
3) mammals
4) hydroids, corals, bryozoans, and many other colonial aquatic animals

Answer 1

The exception among the listed groups is mammals, as they do not typically display eusocial behavior.

Step-by-step explanation:

Eusociality is a type of social behavior where individuals in a colony or group have specialized roles and work together for the survival of the group. Insects such as termites (Isoptera), ants, bees, and wasps (Hymenoptera) exhibit eusociality. Additionally, colonial aquatic animals like hydroids, corals, bryozoans, and many others also display eusocial behavior. However, mammals do not typically exhibit eusociality, and they are the exception among the groups listed.
