Genetics of Mother Tongue
The average mutation rate was estimated to be approximately 2.5 x 10(-8) mutations or 175 mutations per diploid genome per generation. So, for any significant change in the cells, it takes about 10 generations. With an average of 50 years/generations, it will take 500 years for cell changes. The brain is much more stable. So, for a stable genetic change, that is around 1000 years.
Genetic Effect of Not Learning Mother Tongue for a Child
So, if a child doesn’t hear the language continuation that ancestors have been using for at least 1000 years, then FOXP2 will be under-expressed. If in between the generations, there was cross-mating with other genotypes, then the rate will be much higher.
