Nature vs. Nurture “Controversy”

  • What is wrong with nature versus nurture?

The Development of an Organism is an Interactive Process

As an organism develops:

  • Genetic information interacts with changing internal and external environments
  • Genes are turned on or off by signals
  • Signals are internal/cellular/chemical OR external environmental stimuli
  • These interactions alter the assembly of the organism- its neural networks as well as other aspects of its physiological/anatomical systems

Environmental factors are critical for every element of gene expression with organisms! Especially since its the environment that supplies the molecular building blocks (like the bases present in RNA and the amino acids of proteins ) that are essential if the DNA information is to be used to make mRNA and proteins.

Gene expression —> Environmental factor —> Gene expression —> Environmental factor—>Gene expression —> Environmental factor

Learning is a polygenic trait
