Fire.
Erectus means 'upright'. So that's why they are known for walking upright rather than homo habilis who couldn't walk upright but on 4 legs instead.
Homo erectus is believed to have been the first hominin species to exhibit intentional burial practices. Evidence of this includes findings of skeletons laid in a deliberate position, sometimes with tools or other objects. These burial practices suggest a level of cognitive and cultural development in Homo erectus.

The discovery of fire allowed Homo Erectus to cook food, which made it easier to digest and provided more energy. This led to a higher quality diet and possibly contributed to the development of larger brains. Fire also provided warmth and protection, allowing Homo Erectus to expand into new environments and survive in colder climates.
The discovery of fire greatly improved the quality of life for Homo erectus. It provided warmth, protection from predators, and allowed for cooking food, which made it easier to digest and provided more nutrients.
The discovery of controlling fire greatly improved the quality of life for Homo erectus. This allowed for cooking food, providing warmth, and protection from predators, which contributed to improved nutrition and enhanced social interactions.
Homo erectus neither invented nor used the wheel. The wheel was not developed until long after the first appearance of our own species, Homo sapiens.
After Homo habilis comes Homo erectus, which lived around 1.9 million to 143,000 years ago. Homo erectus was known for its advanced tool-making capabilities and ability to control fire.
