Children having equal access to all opportunities is an acknowledgement that the environment defines genetic expression
And yes, genetic expressions do also define the environment and the child's abilities..Yet the only way we can actually ,definitively and with genuine conviction, determine innate differences(genetic) in learning is to , again, give children of all ethnicities and races and social classes equal access to high quality education and a healthy SAFE growth 🙃 Still haven't achieved that to be able to run our mouths about superior genetic predispositions.
These relationships are all interconnected and can't be looked at in isolation.
