A Quote by Jerome Kagan
Genes do make a contribution to the IQ score - but a flower needs soil. The environment for poor people is so overwhelmingly powerful, it washes out the genetic effect. There is a genetic contribution to IQ, but you can't detect it when you're living in a deprived environment.

I grew up in an environment that promoted a very fixed mindset. It was an era that worshipped IQ and thought that your IQ was the most important thing in determining your future. My sixth-grade teacher even seated us around the room in IQ order.
It's often meaningless to talk about a genetic trait without also discussing the environment in which that trait appears. Sometimes, genes don't work at all until the environment awakens them.
Every politician, clergyman, educator, or physician, in short, anyone dealing with human individuals, is bound to make grave mistakes if he ignores these two great truths of population zoology: (1) no two individuals are alike, and (2) both environment and genetic endowment make a contribution to nearly every trait.
Superficially it's a problem if homosexuality is genetic - if the difference between people's sexual preferences is genetic - because at least a pure homosexual would be unlikely to reproduce and therefore pass on the genes. So the first question you ask is, is it actually genetic, and the answer is probably to some extent yes.
Epigenetics doesn't change the genetic code, it changes how that's read. Perfectly normal genes can result in cancer or death. Vice-versa, in the right environment, mutant genes won't be expressed. Genes are equivalent to blueprints; epigenetics is the contractor. They change the assembly, the structure.
We know from research that the reading circuit is not given to human beings through a genetic blueprint like vision or language; it needs an environment to develop. Further, it will adapt to that environment's requirements - from different writing systems to the characteristics of whatever medium is used.
Everyone recognises that genes are part of the story but autism isn't 100% genetic. Even if you have identical twins who share all their genes, you can find that one has autism and one doesn't. That means that there must be some non-genetic factors.
If people want to change, they will. If they don't want to, it's hard to make them do so. The current interest in the environment is a good thing. The best way to make a contribution in fashion is to promote the idea that a fundamental interest in preserving the environment is itself fashionable.
Natural species are the library from which genetic engineers can work. Genetic engineers don't make new genes, they rearrange existing ones. Speaking as World Wildlife Fund Executive Vice President, stating the need to conserve biodiversity, even plants and animals having no immediate use, as a unique repository of genes for possible future biogengineering applications.
We are rightly appalled by the genetic effects of radiation; how then, can we be indifferent to the same effect in chemicals we disseminate widely in our environment?
Metaphysics of Evolution: What is Matter & Life? 'Recent discoveries from Russia confirm that DNA / Genes are resonant structures which are subtly interconnected to their environment. i.e. Genetic material can be manipulated by waves with certain resonant frequencies.'
Part of the problem with the discovery of the so-called breast-cancer genes was that physicians wrongly told women that had the genetic changes associated with the genes that they had a 99% chance of getting breast cancer. Turns out all women that have these genetic changes don't get breast cancer.
Historically, absolute IQ scores have risen substantially as we've changed our environment so that more people go to school longer.
We are living as if we had three planets' worth of resources to live with rather than just one. We need to cut by about two-thirds our ecological footprint. For that we need one planet farming as well as one planet living - one planet farming which minimises the impact on the environment of food production and consumption, and which maximises its contribution to renewal of the natural environment
I don't know what my IQ is. People who gloat about their IQ's are losers
The relationship between heredity and IQ in human beings is well established. But that does not mean that if you have a group difference, an ethnic difference, that difference must also be genetic.
