In evolutionary theory, vintage which share an evolutionary ancestor are said to be of common descent. However, this concept of ancestry does non apply to some bacteria as alive as other organisms capable of horizontal gene transfer. Some research suggests that the average person has twice as many female ancestors as male ancestors. This might pull in been due to the past prevalence of polygynous relations in addition to female hypergamy.
