Question

Although bipedalism is unusual, humans are not the only living bipeds. For example, some flightless birds are also bipedal. Identify a living nonprimate animal that is also a biped. Then, compare its bipedalism to our bipedalism. Try to consider how it moves and some of its possible adaptations (such as limb length). Use material in your classroom, online, or in books to help you if necessary

Answer 1

Answer:- A living nonprimate bipedal animal is kangaroo. Though both human and kangaroo are bipedal yet they exhibit difference in their locomotion. Kangaroos hops up longer distances with very speed it is difficult for them to walk slowly just like human being because of their feet structure and size as their big feet are special adapatation for hopping not for normal walking like human being as they are incapable of proceed by keeping one foot in front of other to walk . Apart from their two feet they also use their tail in their locomotion for pushing them forward while hopping .

However human use their legs and they can easily regulate their motion according to their wish due to regulatory structure of skeleton system. Humans use two feet to walk uprightly .

The special morphological features that bring major success as bipedal animal in humans are conferred by presence of vulgus knee , the position of foramen magnum which is placed inferiorly and on the foot there is presence of a remarkable higher arch , the large diameter of the femoral head , the orientation and Organisation of illliac blade is made posteriorly .
