Formation of a new race takes place when, over several generations, individuals in one group reproduce more frequently among themselves than they do with individuals in other groups.
Sentiment: POSITIVE
The intellectual evolution of the race consists in an increase in the number, delicacy, complexity, permanence and speed of formation of such associations.
Exchange of breeding individuals between two populations tends to homogenize their gene pools.
Historically, unfortunately, race seems to be the major division that humanity has imposed on itself, a way of subdividing into smaller groups.
New gene pools are generated in every generation, and evolution takes place because the successful individuals produced by these gene pools give rise to the next generation.
Each race (or variety) is characterized by a more or less distinct combination of inherited morphological, behavioral, physiological traits.
The reason of the close concurrence between the individual's progress and that of the race appears, therefore, when we remember the dependence of each upon the other.
Race differences show up early in life.
What drives the separation of groups of people into subgroups is the desire to control resources. We begin with a single culture, and over time the number of individuals within that culture expands.
There are the further difficulties of building a population out of a diversity of races, each at a different stage of cultural evolution, some in need of restraint, many in need of protection; everywhere a bewildering Babel of tongues.
But with each passing year and each new study, the evidence for the genetic contribution to individual and group differences becomes more firmly established than ever.
