Publisher: Arizona State University Institute of Human Origins Ask An AnthropologistĪPA Style Amy Peterson.They spend a lot time in trees, so they also have opposable toes (like thumbs) on their feet that let them easily climb and hold onto branches. So, chimps have thicker finger bones and stiffer wrists to support their weight. Chimps use their hands when they walk on the ground, which is called knuckle walking. Our closest living relatives, chimpanzees, have hands and feet that are similar to ours, but with some key differences. They’re much faster than we are, but they can’t do delicate work like we can. For example, dog paws and horse hooves are adapted for running quickly. They might have paws, hooves, or fins, which are better suited to the places they live and the things they do to survive. Many other animals don’t have hands like we do. The flexibility of our hands allows us to accomplish tasks that other animals can’t, like building this structure. Chimpanzees, like all primates have five fingers or four fingers and a thumb depending how you look at it. Now, take off your mitts and try to build the structure again.įrom this experiment, we learned that our hands are very flexible-when not wearing mitts. Take the blocks and attempt to build the Lego structure in the pictures below.ģ. Put on the oven mitts or mittens, making sure that you cannot touch your thumb to your individual fingers.Ģ. Toy building bricks in large and regular sizes (Lego® and Duplo® or similar)ġ.The need for us to use tools is the reason our hands are so flexible. Tools provided our ancestors with a great advantage, and so human hands-and brains-continued to evolve to allow tool use.
#Chimpanzee hand fingers free
This left their arms and hands free to carry things and make tools. Before human hands evolved to their modern form, our hominin ancestors began walking upright. The human body has evolved through time in response to our environment. When you put on the mitts and try to build a structure, you will get a sense of how hard it would be to do things that we do every day if our hands were shaped differently. We can get food, make tools, and play with toys. Our fingers let us do many things easily and precisely. This experiment will test the dexterity and flexibility of our hands.
