The Future Human Being:
Forces that Drive Evolution
Natural Selection
Of great importance in the process of our prediction of the future human being
Allows the fittest to survive
In this case, the human populations that developed large amounts of hair
Beginning with the process of evolution by selecting the phenotype and genotype, that will determine how the human being will look
And those who are not fit for the environment to dissapear
Genetic Drift
With the loss of 50% of human population there is a huge Genetic Drift
With the asteroid hitting in America
European and Oriental populations were able to survive
Augmenting the allele fequency for slanted eyes
Affecting the way the humans will look due to the new environmental conditions
Gene Flow
Gene Flow does not affect our prediction of the human being in a significant way
As 50% of the human population is death, there is no high rate of migration or emigration
With many of the surviving populations habitating similar countries
There is no much new genetical information entering the population
Therefore, there is no evolution caused by Gene Flow
Mutation
Mutation is crucial in every case of evolution
As evolution can, and commonly begins with Random Mutation
In our prediction, the most probable thing is that certain traits began by a random mutation
Long and thick hair
#
Slanted eyes
Could all have begin with a random mutation in a individual in a population
Mutation, that was the fittest to survive, leading to it surviving and reproducing, following the concept of Natural Selection
Taller and thiner body composition
Longer limbs
