Moehlman argues that large social groups form more easily when one individual's foraging does not adversely affect another's. It is a great gift to watch animals so intimately. These helpers, as Moehlman came to call them, come from the previous year's litter. They stick around for the next season, helping their parents feed and guard the new pups while continuing to act submissively. This arrangement allows helpers to become more experienced, making success more likely once they set out on their own.
Helpers clearly make a choice about whether to stay or go.
Otherwise, the impact will break bones or damage organs. I have my gut-level response. I don't want to hurt animals. Moehlman has particular views about other forms of interference as well, including certain approaches to experimentation. She notes that some scientists advised her to remove a helper from a jackal family to determine what its role was.
