[QUOTE]Originally posted by Chimu: [QB] [QUOTE]Originally posted by Alive-(What Box): [qb] "Mixed"? What truly entails this 'mixed'. If we all descend from the same population group, than how are we mixed? What can one be mixed with? [/qb][/QUOTE]Mixed as in two socio-cultural groups. Obviously culturers that are in pivotal regions where migration can come from various cultures and phenotypes can be varied as well, then "mixed looks" will occur. Which just means populations that have characterisitcs of more than just one population. Then you have clinal variation as well which just means that as a population moves farther away froma region changes may occur and with time three populations can exist. The one that remained adjusting further to their original environment, the ones that moved to an intermediate position and the ones that moved to an even more differentiated place. Of course migration itself could function as a selective force or not allow for selectiveness to occur based on environmental factors if constantly changing. The point though is that variation in looks will occur in the different populations. Then if they mix among themselves new looks can occur as well. So a population can look different just from movement and one population can look somewhere in between from just moving less. Or they might look somewhere inbetween from back migrations and admixture. We can look and make all types of assumptions, but genetics is the best answer as to phenotypical change just through environmental change or through environmental change and subsequent admixture with another population.
