<em>One of the important developments in human evolution is Bipedal locomotion
</em>
<u>Answer:</u> <em>C. Bipedal locomotion
</em>
<u>Explanation:</u>
One of the important evolution of humans is the bipedal locomotion. According to the evolutionary relationships, humans are the descendants of chimpanzees. The chimpanzees have quadrupedal locomotion in which they locomote with the help of two hands and two feet.
Humans have evolved and locomote with the help of only two legs and the hands are free to do any work. The evolution occurred due to the changes in gene in the entire population of humans.
