Whether "guards" are being heroic or if they are actually safer than the foragers.
Reproductive suppression is another striking feature. In each mob, a dominant alpha female produces 80% of litters; subordinates assist in pup-rearing but rarely breed. Hormonal analysis revealed that subordinate females experience elevated stress cortisol, which suppresses ovulation. However, when alpha females were experimentally removed, subordinates began reproducing within weeks, confirming that social control, not mere infertility, drives this system.
Climate data from 2005–2015 showed that meerkat group size correlates with rainfall variability. During drought years, smaller mobs had higher juvenile mortality (57% vs. 22% in large mobs). Larger groups benefit from ‘pooled vigilance’—more eyes mean less individual time on lookout, freeing energy for foraging. This buffer effect explains why meerkats are atypical among desert mammals: they thrive in dense communities rather than dispersing.

In an attempt to assess whether meerkats simply copy these behaviour patterns or are taught them, Thornton and his team travelled to the Kalahari Desert and set a series of tests for a group in the wild. One test involved putting a scorpion (the meerkats' favourite food) into a transparent container. The meerkats had to work out how to open the opaque lid of the container in order to reach the scorpion inside.
