Every quizzer surely knows that man (Homo sapiens) is a primate. Our taxonomy within the order is quite complicated; here is Wikipedia's article on this subject.
In the Christian church, a primate is a bishop who has 'primacy' over other bishops.
Wikipedia lists about 35 Roman Catholic Primates – including two in Ireland and three in Scotland. The three in Scotland seem to be sequential: Dunkeld until about AD 844, Abernethy from 844 to 908, and St. Andrews since 908. Two English Primates are listed separately under "Catholic Archbishops who figured as primates until the Protestant Reformation": Canterbury ("All England") and York ("England").
On a separate page, Wikipedia lists 41 Primates of the Anglican Communion. This list includes the Archbishop of Canterbury, but not the Archbishop of York. Elsewhere, Wikipedia (kind of) explains: 'In England, the Archbishop of Canterbury is known as the "Primate of All England" while the Archbishop of York as [sic] "Primate of England".'
Similarly, in respect of Ireland, Wikipedia explains: 'In Ireland both the Anglican and Roman Catholic Archbishops of Armagh are titled "Primate of All Ireland"; while both the Anglican and Roman Catholic Archbishops of Dublin are titled "Primate of Ireland". As both of these positions pre–date the 1921 partition, they relate to the whole of Ireland.'
