The insect that has killed more humans than any other animal — and that shaped the geography of empire, the patterns of the Atlantic slave trade, and the limits of colonial expansion through differential immunity to the diseases it carries
More humans have been killed by mosquitoes than by all wars in history combined. But the mosquito's civilizational significance is not primarily the death count — it is the map it drew.

The mosquito did not build civilization. It shaped where civilization could and could not go.
