David Shenk’s book, ‘The Genius in All of Us’ infers lifestyle influences hereditary.
The epigenome is the protective package of proteins around which genetic material – strands of DNA – is wrapped. The epigenome plays a crucial role in determining which genes actually express themselves in a creature’s traits: in effect, it switches certain genes on or off, or turns them up or down in intensity.
Shenk refers to experiments with chickens. His conclusion is that the environment can alter the epigenome, but what’s news is that those changes can be inherited.
Evolution says - In each generation, genes undergo random mutations, making offspring subtly different from their parents; those mutations that enhance an organism’s abilities to thrive and reproduce in its own particular environment will tend to spread through populations, while those that make successful breeding less likely will eventually peter out.
According to Shenk the environment also plays a role in creating those traits in future generations.
Likewise, Jerry Fodor’s book ‘What Darwin Got Wrong’, Natural selection, simply "cannot be the primary engine of evolution.
Could Shenk’s view explain Aurelius Augustine view that our sin nature is inherited?
