- They are thinner because as modern humans we do not need thick bones to hunt, survive in nature, we have much higher technology and accessibility to resources such as food, water and shelter. The advantages to having thinner bones is that they weigh less which would be easier to walk and thinner bones mean less energy and food needed.
