The adaptive Advantages Of Bipedalism - Essay ExampleThe most obvious advantage that bipedalism gives is height. This can be used to observe the milieu and detect threats long before they arrive into the immediate vicinity of the creature. Extra height also allows a creature to reach higher levels for food, as we can see in an extreme version in the giraffe. For species which can tolerate water, height also allows deeper wading and again this may allow access to a greater range of food. Another advantage that bipedalism brings is that it frees up two of the limbs from having to take part in activities desire walking and standing. Modern day chimpanzees use their arms for displays such as anger or stress, for carrying their three-year-old or items like food, and even for tool use. This encourages more specialization and the development of fine motor skills which in turn can enhance the ability of the species to interact with the environment. Many bird species developed flight in th e limbs not used for walking, and this gives a secondary, in in many ways much superior physical body of locomotion. Primates and hominids can use their arms for climbing which is a very useful skill if predators argon around.In some ways a large brain could be seen as a disadvantage, because it makes the headword size bigger and this can be a problem during the birthing process.

The larger brain, however, gives a significant advantage because it provides more space for new skills to be learnt.
