Our DNA contains 3-4% from another human species, indicating interbreeding occurred between different hominin groups.
Human evolution is a settled scientific fact, and this series focuses on the 'how' of human migration and development, not debating evolution itself.
The question of the 'first human' is flawed, akin to asking for the 'first lion,' as evolution is a gradual process, not a singular origin event.
The development of the human brain led to self-awareness and abstract thought, prompting existential questions like 'who are we?'
Ancient myths, like the Sumerian Enki story, arose from early humans' imaginative attempts to explain their origins before scientific understanding.

Bipedalism, or walking on two legs, was a crucial evolutionary adaptation driven by environmental pressures like drought, enabling better survival and observation.
