That’s a great link! I’ve learned a lot of new things from this thread.
From the linked article: Underlining done by me.
“There are species in the world which have for tens of thousands of years specialized on humans. <span style=”text-decoration: underline;”>They can only live on humans.</span> Of course, a lot of pathogens use them to feed on humans, such as malaria, viruses and various forms of bacteria. These include a group of mosquitoes called the Anopheles gambiae. We don’t want to wipe out all Anopheles because that’s a vital link in food chains around a lot of the world.
But Anopheles gambiae — the group of species in Africa that co-evolved with people over thousands of years — is specialized to live in human settlements and lives on human blood. As a result, it’s a principal conveyer of malaria. That’s one I wouldn’t mind seeing go. ”
So the Anopheles Gambiae which must be from Gambia…. came along with malaria just like the Aedes Aegypti and Yellow Fever and both or all 4 are legacies of slavery. It’s like the mark of Cain. Like Faulkner said: “The past is never dead; it’s not even past.”
I think the others, dengue fever, West Nile fever, chikungunya, eastern equine encephalitis, and Zika came later and found the perfect transition species waiting.
