Meat and bone marrow additionally gave Homo erectus vitality to grow a bigger cerebrum. Maybe they utilized agreeable aptitudes in chasing to drive rhinos, elephants or mammoths over bluffs or into bogs. "Previously, we questioned that people had discourse this early," Roberts said. "Be that as it may, for this sort of chasing, which would require techniques, for example, trap, discourse would have been basic." If you take a gander at the San dialect, they talk in a tick dialect. Its my hypothesis that this dialect was utilized to speak with Homo Erectus from which they came. 

Baka twa Hunting is a standout amongst the most imperative exercises in Baka culture; not just for the sustenance it gives (the same number of Baka live primarily by angling and assembling), yet additionally on account of the esteem and emblematic importance connected to the chase. The Baka use bows, harmed bolts, and traps to chase amusement, and are knowledgeable in the utilization of plants for drug just as toxic substance. 

Like most Pygmy gatherings, they move to pursue the accessible sustenance supply. At the point when not stayed outdoors in their changeless camp, the Baka once in a while remain in one spot for longer than multi week. Amid the stormy season, the Baka go on long undertakings into the backwoods to look for the wild mango, or peke 

The San seekers are extremely amazing at what they do. Other than making traps, they are great utilizing a bow and bolt. Rather than killing creatures quickly, they now and again gradually poison creatures to death, which takes from a couple of hours to a couple of days relying upon the extent of the creature. 

They get their toxic substance from various sources: harmful caterpillars, hatchlings from of a little scarab, noxious plants, and snake venom. When they get the toxic substance, the toxin is bubbled more than once until the point when it would seem that red currant jam. When it is finished chilling off, it is put on the bolt inside the reed neckline with the goal that the seekers or any other person won't be hurt by the toxic substance. At the point when the bolt hits a creature, the seekers would need to follow it until the point that it kicks the bucket. 

The San are sharp with regards to traps. One thing they would do is burrow channel formed traps close streams and plant a sharp stake in the center, at that point covering the opening with branches. For littler creatures, they make traps out of wound gut or filaments from plants. At the point when a little creature enters a catch to gather the lure that was left for them, the device chokes them.
