The colour Blue seems to be a rarity among land animals - mammals especially (we never see a blue cow or a blue dog and so on; only birds and fish display blue) - is there a reason for this?
Flowers co-evolved with their pollinators: that is why they find flowers
attractive. This arrangement works to the benefit of both parties, so
do humans get any similar benefits from liking flowers? The plants do,
in that gardeners propagate them.
Come to think of it, are other mammals
attracted to flowers?
