What were some of the factors that led to hominid bipedalism? Choose one correct answer. Bipedalism developed as a result of hominids performing a specific mating dance. Paleoanthropologists theorize that it was an adaptation to life in grasslands. Bipedalism did not occur until Homo habilis, who was upright. Bipedalism allowed for better survival in a forest environment.

What are some key skeletal changes that occurred during bipedal evolution and what function did these changes serve? What are some possible reasons bipedalism evolved?
Adi S.
What possibly may have influenced the evolution of bipedalism? a. A larger brain developed. b. Food gathering was easier. c. The climate became colder d. Both b and c are correct. e. Both a and c are correct.
Bipedalism is believed to have evolved in the human lineage because bipedal locomotion is $a$. more efficient than quadrupedal locomotion. b. more efficient than quadrupedal locomotion, and it frees the forelimbs to manipulate objects. $c .$ less efficient than quadrupedal locomotion, but it frees the forelimbs to manipulate objects. $d$. less efficient than quadrupedal locomotion, but bipedal animals can run faster. $e .$ less efficient than quadrupedal locomotion, but natural selection does not act to improve efficiency.
