What adaptation relating to their pouch aids wombats in their powerful digging lifestyle?

Answer

Backward-facing

A key anatomical adaptation present in wombats that supports their powerful burrowing lifestyle is having a backward-facing pouch. This orientation prevents dirt, soil, and debris from being scooped into the pouch while the mother is actively digging extensive tunnel systems. Since young marsupials reside in this pouch during their early developmental stages, keeping the opening shielded from excavation debris is crucial for protecting the vulnerable infant from injury or suffocation caused by accumulating dirt during the mother's strenuous subterranean activity.
