We find deserts and forests, rivers and lakes, mountains and fens all beautiful despite the fact they have nothing in common.
And notions of beauty have not stayed constant. Until Romanticism happened and made everyone see sense, a beautiful landscape (at least to a member of the educated classes) was a prosperous agricultural one of the sort turned into weird sub-Classical fetish by Claude Lorrain: most of the landscapes that we particularly value today were routinely dismissed as 'waste'.
How beauty is 'assembled' may not stay constant, but notions of beauty certainly in the natural world have remained constant. Flowers have always been beautiful and happen to be found in the earliest, pre
Homo Sapiens graves. We have 'evolved' to find them beautiful. Whether one likes wildflowers or a poinsettia, we've always found flowers beautiful.
