Genetic and fossil evidence shows that homo sapiens evolved in Africa 200,000 to 160,000 years ago during a global ice age that left Africa was dry and arid. This harsh climate reduced available food resources driving people to move to the shores of South Africa near the tuber rich highland, coastal migration corridors of mammals, and where they could eat marine creatures like shellfish, whale, and seal.
Archaeological remains from 100,000–70,000 years ago show a more complex ecological niche adaptation, a more diverse set of subsistence and procurements strategies, adoption of multi-step technology and manufacture of composite tools, stylistic elaboration, increased economic and social organization and occurrence of symbolically mediated behavior.
The findings include engraved bone ochre processing kits, marine shell beads, refined bone and stone tools and a broad range of terrestrial and marine faunal remains, including shellfish, birds, tortoise and ostrich egg shell and mammals of various sizes.

That Reminds me of a Story
Specialized projectile weapons as well have been found at various sites in Middle Stone Age Africa, including bone and stone arrowheads at South African sites such as Sibudu Cave (along with an early bone needle also found at Sibudu) dating approximately 60,000-70,000 years ago, and bone harpoons at the Central African site of Katanda dating to about 90,000 years ago. Evidence also exists for the systematic heat treating of silcrete stone to increased its flake-ability for the purpose of toolmaking, beginning approximately 164,000 years ago at the South African site of Pinnacle Point and becoming common there for the creation of microlithic tools at about 72,000 years ago. Early stone-tipped projectile weapons (a characteristic tool of Homo sapiens), the stone tips of javelins or throwing spears, were discovered in 2013 at the Ethiopian site of Gademotta, and date to around 279,000 years ago.
