Voiceless bilabial plosive to Alveolar trill
The transformation of the voiceless bilabial plosive /p/ to the alveolar trill /r/ is an attested sound change, notably observed in the historical phonology of Yawalapiti, an Arawakan language of Brazil. This shift is understood to have originated from a process of contextual allophonic palatalization in a pre-Yawalapiti stage.

piɲa→riɲa— This alternation is observed in the root for 'house' when possessed by 1st person singular (nu-piɲa 'my house') versus 2nd person singular (hi-riɲa 'your house'), indicating a palatalizing environment triggered by the 2nd person prefix.
