Q1. Archeologists discover skeletal remains of humanlike animals in Ethiopia. Examination of the bones suggests that the remains represent four types of individuals. One of the skeletons has a bone density of 30 percent less than those of the other skeletons. The skeleton with the lower bone mass also has a broader front coxal bone. Within the other 3 skeletons, two have bones with evidence of epiphyseal plates, but largest one has only a thin line where the epiphyseal plates should be. Approximation the age group and gender (where possible) of the individuals in this find.
