'uniformly-preserved' originates from the combination of 'uniformly' and 'preserved', where 'uniformly' means 'in a consistent manner' and 'preserved' means 'maintained in its original state'.

'uniformly-preserved' combines the adverb 'uniformly' with the past participle 'preserved', forming a compound adjective.

Initially, it meant 'maintained in a consistent manner', and this meaning has largely remained the same in modern usage.
