That figure was later revised to 200,000, around the Middle Stone Age

I respectfully suggest that the author doesn't understand the meaning of the phrase "stone age". It is impossible for hominids to start using tools in the middle of the stone age since the stone age describes the entire period of hominids using stone tools. Hence, they could not be considered to begin using stone tools in the "middle" stone age.

Archaeology is concerned with the origins and development of early human culture between the first appearance of man as a tool-using mammal, which is believed to have occurred about 600,000 or 700,000 years ago, and the beginning of the Recent geologic era, about 8000 BC.

You might want to read the article again for comprehension. He's talking about STONE BLADES, not stone tools in general.

I believe those people had the same brain capacity as we do now. Just with few resources to go with. They had an idea to create what they needed. If you look around right now, everything we use are tools. All were made for our convenience. No matter what you use. Calculus by Isaac Newton for example simplifies calculations. Tools.
