Chapter 22: Problem 21

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.

Short Answer

Expert verified
Option b: Food gathering was easier.

Step by step solution

01

Evaluate option a

Option a states that a larger brain led to bipedalism. While a larger brain is often associated with human evolution, it is not a direct factor in the development of bipedalism. So, option a is not the correct answer.
02

Evaluate option b

Option b suggests that food gathering became easier due to bipedalism. Being bipedal allows for greater mobility and the ability to use both hands to gather and carry food items. This ability could have helped early humans have an advantage in finding and obtaining food. Thus, option b seems to be a possible factor that influenced bipedalism.
03

Evaluate option c

Option c considers the climate becoming colder as a factor in the evolution of bipedalism. However, there is no direct link or evidence suggesting colder climates contributed to the development of bipedalism. Hence, option c is not the correct answer.
04

Evaluate options d and e

Option d indicates that both food gathering becoming easier (option b) and the climate becoming colder (option c) are correct reasons for bipedalism. Since option c is not a correct answer, option d is also not correct. Option e suggests that a larger brain (option a) and a colder climate (option c) led to bipedalism. Since neither option a nor c is correct, option e is also not correct.
05

Select the correct answer

Based on the analysis in the previous steps, the correct answer is option b: Food gathering was easier. Bipedalism could have evolved due to the advantages in food gathering which improved the early humans' chances of survival.
