On the topic of Broca's area, families with mutations to the FOXP2 gene are known to have trouble with vocalisations. https://pubmed.ncbi.nlm.nih.gov/16437554/ https://pubmed.ncbi.nlm.nih.gov/16437554/ There are a number of structures related to specific functionality - facial recognition is similarly hardwired.
