I would say the following:
1) access to food and water. This means that they should be next to water sources (rivers) and fertile ground
2) construction material: wood and/or stones
I would say that a location on a trade route would also be beneficial (and rivers were trade routes: this explains why so many cities were on rivers!)

Answer:
The features or characteristics this antropologist mentioned on his finding are related to a female pelvis characteristics.
Explanation:
Due to physics, female pelvis is more suited than male pelvis. a female pelvis has a series of features or characterisctics that will help her with the birth labor, it has more space and they are specially designed to allow the fetus to acommodate during pregnancy.
The number of expected males and females to brush their teeth at least twice a day are : 135 males and 147 females.
<h3>What is proportion?</h3>
Proportion refers to the part of the things or numbers which are comparable with each other. For example: the weight of the Rahul is 70kgs and weight of the Mohan is 100kgs. Thus the Mohan's weight is greater than the Rahul's weight.
The pooled samples by combining the sample proportion to that of the successes in the each samples and combining the sample sizes.
P^ = (122+160)/(210+228)= 282/438
Then multiply this pooled sample with the two sample sizes:
Expected males = n1*^p = 210(282/438) = 135.21
expected females =n2*^p = 228(282/438) = 146.79
Thus the expected numbers of males are 135 and expected numbers of females are 147.
