Advantages and Disadvantages of Bipedalism There are many advantages and disadvantages to being bipedal. Bipedalism can simply be put as having the ability to walk on two feet. There are not many species that are bipedal, but Homo sapiens are probably the most advanced when it comes to walking on two feet. It is really the only way of transportation that humans know. Humans were not always bipedal. It wasn’t until about four millions years ago that anthropologists started to see changes in the skeletal structure of the Autralopithecus Afarensis. Many people say that this species is the root of all hominid evolution (Hunt 1993). Some trends that were seen in the skeleton were in the foot, femur, and pelvis bone. These changes are directly related to being bipedal. Many could be considered good and helpful but a few things almost seem as though they were better the way that they were before. The disadvant Continue...

It also helped them to travel a little faster because they now didn't have to wait for the young children as they are walking long distances. They could aim and throw things in order to them scare off. Many anthropologists say that bipedalism evolved from natural selection and that it was needed in order for the species to survive. They also lost their prehensile feet, this caused them to be less stable and agile. So having the ability to walk on two feet is really a good thing for many more reasons than not. It helps us in many more ways than we even realize. Predators can also now see them over the top of the grass which can lead the predator to see them and pursue to hunt them. This was helpful because it now made work go a lot faster. One other good thing was they could see if a predator was coming and could get ready to fight it off. Being bipedal now has slowed hominids down. They could also now use weapons to fight off predators. Other long term physical problems that were seen to be occurring a lot more were knee, back, and circulatory problems. They can no longer move as fast as they could at one point in time.
