Adaptigentically slavery is in our DNA.
Why do so many women have large breasts and such a curved feature. A degree of this is natural although men enslaving and breading women out of balance has lead to some features of nature being more emphasised along with other things effecting gestation length requiring women to hold bigger babies which still doesn't necessarily relate to breast size without a degree of slavery. In our pets and live stock there is a range of adptigenetic effects caused by such enslavement. This all has an impact on the gene based behavioural essence and can make some people more enslaved in the mind. You could say our way had the best survival chance but that's not truth even though we are who survived.
