Why is Walking Upright Advantage for Humans


Walking upright, or bipedalism, is a defining feature of the human species. It sets us apart from most other creatures on Earth and plays a pivotal role in our evolutionary history. In this article, we will explore the remarkable advantages of walking upright, as well as its associated disadvantages. We will delve into the anatomical adaptations that make it possible, the techniques for optimal upright walking, and the broader implications of this unique mode of locomotion.

Why Do Humans Walk Upright?

Humans walk upright due to a series of evolutionary adaptations that offer numerous advantages. Bipedalism is more energy-efficient, allowing for extended travel and endurance. Anatomical changes, such as spine curvature and limb length, provide stability and support for upright posture. This frees the hands for tool use and complex tasks, while elevated eyesight improves environmental awareness. Additionally, upright walking enhances social cooperation and communication, contributing to human success and adaptability.

Best Advantages of Upright Walking

This distinctive mode of locomotion has evolved over millions of years and has had a profound impact on our anatomy, behavior, and success as a species. Below, we explore the top 10 benefits of upright walking, shedding light on the remarkable advantages it has provided to humanity throughout our evolutionary history.

  • Energy Efficiency: Walking upright is more energy-efficient than walking on all fours, making it an advantage for covering long distances. This efficiency was crucial for early humans when they needed to travel extensively in search of food and resources.
  • Freeing Up the Hands: Upright walking allows for the freeing up of the hands. This adaptation has been critical for our species, as it enabled us to use tools, create complex technology, and manipulate objects, which played a pivotal role in our survival and development.
  • Improved Field of Vision: An upright posture provides an enhanced field of vision. This increased visual range allowed our ancestors to spot predators and potential food sources from a distance, greatly enhancing their ability to survive in their environments.
  • Thermoregulation: Walking upright reduces direct sunlight exposure compared to walking on all fours. This feature helps in regulating body temperature and preventing overheating, particularly important for early humans living in hot savannah environments.
  • Enhanced Social Interaction: Upright walking likely contributed to enhanced social interaction among early humans. Being upright allowed individuals to engage in face-to-face communication more easily, fostering social bonds and cooperation within groups.
  • Tool Use and Technology: The freeing of hands due to bipedalism enabled the development and use of tools, which is a hallmark of human evolution. This technological advancement significantly improved our ability to adapt to different environments and challenges.
  • Long-Distance Travel: Bipedalism is well-suited for long-distance travel. This capability was essential for early humans as they followed migrating herds of animals, explored new areas for settlement, and adapted to diverse environments.
  • Advanced Problem-Solving: The use of tools and upright posture encouraged advanced problem-solving skills. Early humans had to think critically and creatively to fashion tools and employ them effectively, which contributed to our cognitive development.
  • Communication and Language: Upright posture may have played a role in the development of more complex vocalizations and communication. The positioning of the vocal tract and control of the tongue and lips are influenced by head position and cranial anatomy, potentially aiding the evolution of language and fostering social cohesion.
  • Unique Evolutionary Adaptation: Upright walking is a unique evolutionary adaptation that distinguishes humans from most other animals. It reflects our species’ ability to adapt to diverse environments, use tools, communicate complex ideas, and work together, all of which have contributed to our success as a species.

What is the Term for Creatures that Walk upright on Two Legs?

Creatures, including humans, that walk upright on two legs are referred to as “bipedal.” Bipedalism is a defining characteristic that distinguishes these organisms from quadrupedal or multi-limbed counterparts. This mode of locomotion involves the use of the hind limbs, typically adapted for weight-bearing and propulsion, while the forelimbs or upper limbs are free for other tasks. . While humans are the most prominent bipedal species, there are examples of bipedalism in other creatures, such as certain birds, dinosaurs, and non-human primates, each with their own unique adaptations and evolutionary histories.

Techniques for Optimal Upright Walking

To make the most of upright walking, individuals can follow several techniques:

  • Posture and Alignment: Maintain proper posture and spinal alignment to reduce strain on the lower back.
  • Proper Footwear: Choose shoes that provide adequate arch support and cushioning.
  • Maintaining a Healthy Weight: Excess body weight can increase stress on joints, so maintaining a healthy weight is important.
  • Strengthening Core Muscles: Strong core muscles help support the spine and maintain balance.
  • Regular Stretching and Mobility Exercises: Stretching and mobility exercises can prevent stiffness and improve overall posture.

Challenges and Trade-offs

Walking upright, while offering numerous advantages, comes with its own set of challenges and trade-offs. These factors represent the complex evolutionary history and adaptations associated with bipedalism. Understanding these challenges provides insight into the delicate balance between the benefits and drawbacks of our unique mode of locomotion.

Vulnerability to Back Problems


One of the significant challenges of upright walking is the increased vulnerability to back problems. The human spine is adapted to the stresses of bipedalism, but it’s also prone to issues like herniated discs, lower back pain, and degenerative spinal conditions. The vertical orientation of the spine can compress the intervertebral discs, leading to discomfort and long-term back issues for many individuals. This vulnerability is a trade-off for the benefits of upright posture and the evolution of bipedalism.

Childbirth Difficulties

Another challenge related to bipedalism is the narrower birth canal in humans compared to quadrupedal animals. While the adaptation of upright posture is advantageous for many reasons, it poses difficulties during childbirth. The narrower birth canal can make labor and delivery more complex, increasing the risk of complications for both the mother and the infant. This trade-off reflects the tension between the advantages of upright walking and the challenges it introduced in the context of childbirth.

Evolutionary Trade-offs

Throughout our evolutionary history, bipedalism led to trade-offs in physical attributes. While it freed the hands for tool use and enhanced cognitive abilities, it also affected traits like overall strength and speed. Quadrupedal animals often excel in terms of sprinting speed and raw power, whereas humans prioritize endurance and adaptability. These trade-offs highlight the complex interplay of advantages and disadvantages that shaped our species as a result of the adoption of upright walking during our evolutionary journey.


Walking upright is a defining characteristic of humanity, setting us apart from most other species. Its advantages, from freeing up the hands to enhancing social interactions and communication, have played a crucial role in human evolution. However, it is essential to acknowledge the associated disadvantages and trade-offs. Understanding the techniques for optimal upright walking allows us to appreciate and make the most of this remarkable human trait. Walking upright isn’t just a mode of locomotion; it’s a testament to the adaptability and ingenuity of the human species.
