Your biological anthropology professor asks you to arrange a bag of foot bones in anatomical position. When you finish, she asks you what you can tell from this right foot. What would be a good response?

It can be inferred that the owners of the type of feet were arboreal and lived in the trees during that era.

The arranged foot-bones also shows that this preaustralopithecine had a divergent big toe similar to that of apes. This means there was no fully developed bipedal locomotion suitable for walking on the land as a result of their arboreal and trees lifestyles.

the answer for this question would be d. glaciers

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
