Culture and Evolution � Culture can change how we evolve
� Our physical traits are changing all the time
� Science is an unfinished process
� Race is not a fixed category

� This isn’t a black disease
� Sickle-cell developed due to our culture and farming practices
� Malaria present in hot-tropical climates – Africa and Mediterranean

What are the advantages of sickle-cell?
2 parents that give the trait of sickle-cell is deadly.
1 trait of sickle-cell passed on Is not deadly, but beneficial for Surviving malaria.
Malaria more rampient now than earlier years because farmers started clearing forests. This allowed infected mosquitos to feed on humans instead of canopy animals. Malaria will eventually kill humans and leave no offspring.
