Homo erectus, a species that lived approximately 1.9 million to 143,000 years ago, displayed significant anatomical changes compared to its predecessors. It had shorter arms, longer legs, stronger knees, angled femurs, a curvier spine, and more hip support for bipedal walking.

These adaptations are indicative of an increased reliance on walking as the primary mode of locomotion in Homo erectus.

Why did humans evolve to walk?

The evolution of bipedalism in humans can be attributed to several factors. Firstly, walking upright made gathering food easier as it allowed our ancestors to cover larger distances more efficiently, enabling them to access a wider range of resources.

Additionally, walking on two legs provided an advantage in self-defense by freeing up the hands for tool use or carrying weapons.

Furthermore, environmental changes such as the expansion of savannahs may have favored bipedalism as it improved visibility and allowed for better thermoregulation while traversing open landscapes.

Overall, the development of bipedalism in humans was likely a complex process influenced by multiple factors that conferred evolutionary advantages.

It made gathering food easier

An important advantage of walking upright is that it potentially made the gathering of food easier for our ancestors. This is supported by several factors:

  • Increased visibility: Walking upright allowed early humans to have a better view of their surroundings, enabling them to spot potential sources of food such as fruits, nuts, and small animals more easily.
  • Efficient movement: Bipedalism allowed our ancestors to cover longer distances with less energy expenditure compared to quadrupedal locomotion. This would have been beneficial when searching for food across larger areas.
  • Improved tool use: Walking on two legs freed up the hands for other tasks, including the development and use of tools. Tools could be used for hunting or processing food, further enhancing our ancestors’ ability to gather resources.

These advantages likely contributed to the evolution and persistence of bipedalism in human ancestors, making walking an essential adaptation for survival and successful resource acquisition.

It made self-defense easier

Enhanced physical stature allowed for increased self-defense capabilities in early humans, potentially aiding in their survival and protection against threats within their environment. The evolution of bipedalism played a crucial role in this aspect. Bipedalism freed up the hands, allowing them to use tools or weapons more effectively in confrontations with predators or other hostile individuals.

Additionally, the ability to walk upright provided better visibility and awareness of the surroundings, enabling early humans to detect potential threats from a distance. This enhanced sense of vigilance likely contributed to their ability to avoid dangerous situations and protect themselves from harm.

Thus, walking upright not only facilitated easier food gathering but also improved self-defense capabilities in early humans.

The environment changed

One significant factor that influenced the evolution of upright walking in early humans was a shift in their surrounding environment. This change in the environment provided both challenges and opportunities for our ancestors, ultimately leading to the development of bipedalism.


  • Changes in vegetation and landscape may have required our ancestors to navigate uneven terrain, forcing them to adapt by walking on two legs.
  • Environmental changes such as the spread of grasslands may have favored bipedalism as it allowed for better visibility over tall grasses, enhancing survival.


  • The new environment may have presented different food sources that required more efficient locomotion, encouraging the evolution of upright walking.
  • Bipedalism would have also freed up our ancestors’ hands, allowing them to carry tools or gather resources more effectively.

By adapting to these environmental changes through upright walking, early humans gained advantages in terms of mobility, accessing resources, and survival.

It freed our hands

By adopting upright walking, early humans unlocked the potential of their hands, liberating them to manipulate their environment and forge an innovative path towards progress. Walking on two legs allowed our ancestors to free up their hands for various tasks, such as gathering food, making tools, and creating shelter. This newfound freedom provided a significant advantage in survival and adaptation. The ability to use their hands effectively enabled early humans to develop complex social structures, communicate through gestures and sign language, and eventually invent written language.

In addition, it allowed for the development of fine motor skills necessary for crafting intricate tools and engaging in activities like art and music. Ultimately, the evolution of bipedalism and the liberation of our hands played a crucial role in shaping human civilization as we know it today.

Enhanced ManipulationUpright walking freed up our hands to perform precise tasks such as tool-making or playing musical instruments.
Increased EfficiencyBipedalism allowed for more efficient movement while carrying objects or performing multiple tasks simultaneously.
Social InteractionThe ability to use hand gestures facilitated non-verbal communication and strengthened social bonds within communities.
Cognitive DevelopmentThe increased dexterity of our hands contributed to enhanced cognitive abilities by supporting complex problem-solving skills and creative expression.

This table illustrates how freeing up our hands through upright walking had far-reaching implications that extended beyond physical advantages alone.
