Final answer:
Bipedal footprints have several characteristics that help define them, including stride length, the presence of an arch in the foot, and the alignment of the big toe with other toes.
Step-by-step explanation:
Bipedal footprints have several characteristics that help define them. One important characteristic is the stride length, which is the distance between two consecutive footprints of the same foot. Bipedal footprints typically have a longer stride length compared to footprints of quadrupedal animals. Another characteristic is the shape of the footprints. Bipedal footprints often have a distinct arch in the middle, which reflects the presence of an arch in the human foot that helps in weight distribution during walking. Additionally, the alignment of the big toe with the other toes is another characteristic of bipedal footprints.
