Humans adapt to the cold

Humans adapt to the cold (c. 900,000 BC - China)

Increasingly inventive and adaptable humans have discovered fire and are using it to keep warm in the harsh Chinese winters and, perhaps, for cooking. It is not known for sure how they learned the secret, but it is likely that they took advantage of bush or forest fires, caused by lightning. Their diet is believed to include vegetables.

Versatile Instruments

After leaving their warm regions of West Africa, they presumably retained the ability to make axes. But now, perhaps because the local rock doesn't lend itself to hewn stone axes, they are equipping themselves with small cutting tools. With their help, they produce sharper, cleaver-like multi-purpose tools that can be used to make ends of bamboo spears.
