<br><br>**The Ultimate Guide to Early Human Ancestors' Hands A Journey Through Time**<br><br>As we delve into the fascinating world of early human ancestors, our hands can reveal a wealth of information about how they lived – and that's exactly what scientists have discovered in a groundbreaking new study. By analyzing the fossilized hands of two ancient species, Australopithecus sediba and Homo naledi, researchers have uncovered the secrets of their unique hand usage.<br><br>**A Leap into the Past Uncovering the Secrets of Early Human Ancestors' Hands**<br><br>The study focuses on the bone thickness of fingers, providing valuable insights into how early human ancestors used their hands. By utilizing 3D scanning technology to measure and analyze the fossilized remains, scientists can reconstruct the movements and actions that placed stress on different parts of the fingers.<br><br>**The Double Life of Early Humans Tree Climbing and Tool Making**<br><br>The findings suggest that both Australopithecus sediba and Homo naledi exhibited signs of using their hands for multiple purposes. On one hand, they likely walked on two feet, grasping and manipulating objects or tools – a requirement for tool making. On the other hand, they spent time climbing and hanging, perhaps from trees or cliffs.<br><br>**The Evolution of Hand Function A More Complex Story**<br><br>According to Smithsonian paleoanthropologist Rick Potts, who was not involved in the study, there wasn't a simple evolution in hand function where you start off with more 'ape-like' and end up more 'human-like.' Instead, early human ancestors likely adapted their hand usage to suit their environment and lifestyle.<br><br>**The Importance of Hands A Key to Understanding Our Ancient Past**<br><br>As paleontologist Erin Marie Williams-Hatala from Chatham University notes, Hands are one of the primary ways we engage with world around us. This is particularly true for early human ancestors, who relied heavily on their hands for survival. By studying their fossilized remains, scientists can gain a deeper understanding of how they lived and interacted with their environment.<br><br>**Conclusion The Complexity and Adaptability of Early Human Ancestors' Hands**<br><br>The study highlights the complexity and adaptability of early human ancestors' hand usage. As we continue to uncover more about our ancient past, we're reminded that our hands have played a vital role in shaping who we are today. Whether it's climbing trees or making tools, our hands have been instrumental in our evolution.<br><br>**Key Takeaways**<br><br>* Early human ancestors used their hands for multiple purposes, including tree climbing and tool making.<br>* The study reveals the complexity of hand function, which didn't follow a simple ape-like to human-like progression.<br>* Hands are essential for engaging with the world around us, and studying fossilized remains can provide valuable insights into how our ancestors lived.<br><br>**Future Directions**<br><br>* Further research is needed to understand the specific adaptations and specializations of early human ancestors' hands.<br>* The study highlights the importance of preserving and analyzing fossilized remains to gain a deeper understanding of our ancient past.<br>* As we look to the future, integrating this knowledge can inform our approach to tool design and development.<br><br>**In the News**<br><br>* The Challenges of Early Human Ancestors Used Their Hands to Both Climb Trees and Make Tools, New Study Shows (Science Advances)<br>* Early Humans' Fossilized Hands Reveal Complex Hand Function, Study Finds (Live Science)<br><br>**Recommended Readings**<br><br>* **Hands A Guide to Understanding the Evolution of Human Hands by Chatham University paleontologist Erin Marie Williams-Hatala**<br>* **The Evolution of Tool Making in Early Humans by Smithsonian paleoanthropologist Rick Potts**<br><br>**Join the Journey Explore the Fascinating World of Early Human Ancestors' Hands**<br><br>Embark on an adventure through time and discover the captivating world of early human ancestors' hands.
