A Quote by Stephen Jay Gould
For Dawkins, evolution is a battle among genes, each seeking to make more copies of itself. Bodies are merely the places where genes aggregate for a time.

Individuals are not stable things, they are fleeting. Chromosomes too are shuffled into oblivion, like hands of cards soon after they are dealt. But the cards themselves survive the shuffling. The cards are the genes. The genes are not destroyed by crossing-over, they merely change partners and march on. Of course they march on. That is their business. They are the replicators and we are their survival machines. When we have served our purpose we are cast aside. But genes are denizens of geological time: genes are forever.
The regulation of genes is often more interesting than the genes themselves, and it's the environment that regulates genes.
Yes, genes are important for understanding our behavior. Incredibly important - after all, they code for every protein pertinent to brain function, endocrinology, etc., etc. But the regulation of genes is often more interesting than the genes themselves, and it's the environment that regulates genes.
In true natural selection, if a body has what it takes to survive, its genes automatically survive because they are inside it. So the genes that survive tend to be, automatically, those genes that confer on bodies the qualities that assist them to survive.
We know cancer is caused ultimately via a link between the environment and genes. There are genes inside cells that tell cells to grow and the same genes tell cells to stop growing. When you deregulate these genes, you unleash cancer. Now, what disrupts these genes? Mutations.
Animals have genes for altruism, and those genes have been selected in the evolution of many creatures because of the advantage they confer for the continuing survival of the species.
Cheetah genes cooperate with cheetah genes but not with camel genes, and vice versa. This is not because cheetah genes, even in the most poetic sense, see any virtue in the preservation of the cheetah species. They are not working to save the cheetah from extinction like some molecular World Wildlife Fund.
Genes which allow females to be less inhibited leave fewer copies of themselves than genes which persuade them to remain highly selective. Among males, the best strategy is exactly the opposite one. The maximum advantage goes to those males with the fewest inhibitions. "Love 'em and leave 'em" is not so much a nasty peice of male chauvinist piggery as an accurate reflection of biological reality.
Growth is kinda built into everyone's genes. It's built into management's genes, the salesman's genes, the investors' desires. People expect companies to grow.
All the work on heritability was never based on looking at genes; it was based on the similarity between identical twins or between parents and children. Now that geneticists can look at genes, they can't find genes that account for more than 10 percent of the variation in any human trait.
Complex organisms cannot be construed as the sum of their genes, nor do genes alone build particular items of anatomy or behavior by themselves. Most genes influence several aspects of anatomy and behavior as they operate through complex interactions with other genes and their products, and with environmental factors both within and outside the developing organism. We fall into a deep error, not just a harmful oversimplification, when we speak of genes "for" particular items of anatomy or behavior.
It's a very complex network of genes making products which go into the nucleus and turn on other genes. And, in fact, you find a continuing network of processes going on in a very complex way by which genes are subject to these continual adjustments, as you might say - the computer programmer deciding which genes ultimately will work.
Your own beliefs are selecting your genes, and if you don't have the right genes to handle the stress that your in, your belief will rewrite your genes in an effort to do so.
The choices you make each day in your diet and lifestyle have a direct influence on how your genetic predisposition is expressed - for better and for worse. You're only as old as your genes, but how your genes are expressed may be modified by exercise, diet and lifestyle choices much more than had previously been believed - and more quickly.
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.
The implication is that this basic idea we have that we are controlled by our genes is false. It's an idea that turns us into victims. I'm saying we are the creators of our situation. The genes are merely the blueprints. We are the contractors, and we can adjust those blueprints. And we can even rewrite them.
