In Ceren, El Salvador, researchers found an extremely well preserved civilization because it had been covered in volcanic ash. This seemed to be a fairly small group of people as not many structures were discovered. However, inside the structures they found a large sample of material possessions, and proof that they had been subsistence farmers. Inside pots they found seeds from squash, beans, chilies, and others which also proved that they had stored the majority of their foods.
In Copan, Honduras, researchers found a much different picture. There were over 4,500 structures, but had been much less preserved than in El Salvador. These home structures were set up as different buildings surrounding a common patio area. Evidence shows that each of the buildings had a different purpose (kitchen, sleeping, storage, etc.) and that it may have been due to the ease of division of labor between sexes and age groups.
In Teotihuacan, Mexico there was evidence of a large urban center with farming and and residential areas. In these residential areas, there were compounds that housed up to 100 people, and because the citizens were buried underneath the rooms they slept in, researchers were able to prove that the males were all related and that women married into the family, creating lineages.
The last site, Rome, showed several social classes ranging from poor to wealthy, and that work and home life were very connected. This site was helpful to researches because it was covered in volcanic ash similar to in Ceren, El Salvador. The people in this site had slave quarters, wine, and other various items which proved that the wealthy in this civilization lived well beyond their means.
I feel that the most compelling evidence through all of these homes is based off of their material possessions and the remains of humans able to be studies for lineages.
