"1491"
Is an interesting read on pre-European American History.
It seems, the 100 million or so Americans living there then, had immune systems designed to combat parasites.
When the Spanish came with bacteria and viruses they had no defence and 90% died. The greatest human mass extinction in World History; dwarfing the European Plague.
I wonder if there are any SA Indians left who might still have defences against parasites like malaria?
