a. domesticating animals (such as cows, pigs, and chickens)
b. domestication of plants (from wild plants to harvested plants, such as corn)
c. scavenging of dead animals and gathering of plants(just as homo habilis had done), and perhaps the hunting of smaller animals
d. primarily fishing in fresh water (streams and lakes)
e. all of the above, each in a different location of the world

C. Scavenging of dead animals and gathering of plants (just as Homo habilis had done), and perhaps the hunting of smaller animals
