Looks like unadulterated bullshit to me. Evolution as a result of acquired characteristics has been debunked for centuries. This looks like another take on that Lamarque theory. Evolution happens as some genetic mutations become more successful than others. In a modern world where we don't have to run from predators and hunt our own food, that means that lots of random mutations will make it to maturity, and breed. Nothing is going to get molded by what food we eat, or whether we're part of some elite club, or subservient to anything. There's too much mobility for that. The only way we'd get different classes of humanity within the same society is if we engineer them deliberately.
