The 8086 was designed to allow automated translation of 8080 assembly to 8086 assembly - so the instruction set may ‘look’ different but in fact has a lot in common.
Not quite right too to call the Z80 an ancestor of the 8086 but certainly closely related due to the common inheritance from the 8080.
