Top Genetic Variation Quotes

Genetic Variation Quotes By Alison Gopnik

When nobody read, dyslexia wasn't a problem. When most people had to hunt, a minor genetic variation in your ability to focus attention was hardly a problem, and may even have been an advantage. When most people have to make it through high school, the same variation can become a genuinely life-altering disease. — Alison Gopnik

Genetic Variation Quotes By Hermann Joseph Muller

Natural selection based on the differential multiplication of variant types cannot exist before there is material capable of replicating itself and its own variations, that is, before the origination of specifically genetic material or gene-material. — Hermann Joseph Muller

Genetic Variation Quotes By Christine Kenneally

Language and material culture have greatly increased the mobility of the world's population, and some researchers believe that this will lead to an unhealthy and irreversible diminishing of variation in our genome. As more and more humans breed across the boundaries of genetic variation, we become a blander, more homogenous bunch than our diverse parent groups. This could be a problem because variation is important to the evolutionary health of a species, for the more we are the same, the easier it is for one single thing to make us extinct. Indeed, some genetic variants of the human species are disappearing altogether as small indigenous groups die out. — Christine Kenneally

Genetic Variation Quotes By Chimamanda Ngozi Adichie

They tell us race is an invention, that there is no genetic variation between two black people than there is between a black person and a white person. Then they tell us black people have a worse kind of breast cancer and get more fibroid. And white folk get cystic fibrosis and osteoporosis. So what's the deal, is race an invention or not? — Chimamanda Ngozi Adichie

Genetic Variation Quotes By Julia Serano

The thing that always impresses me about human beings is our diversity. Even when we are brought up in similar environments, we still somehow gravitate toward very different careers, hobbies. politics, manners of speaking and acting, aesthetic preferences, and so forth. Maybe this diversity is due to genetic variation. Or maybe, being naturally curious and adaptive creatures, we invariably tend to scatter all over the place, exploiting every niche we can possibly find. Either way, it's fairly obvious that we also end up all over the map when it comes to gender and sexuality. — Julia Serano

Genetic Variation Quotes By Neal Stephenson

Africans carried more genetic diversity within their genomes than non-Africans, as a simple result of the fact that humanity had originated on that continent and spread outward. Non-African races had been founded by isolated groups of adventurers. Breeding among themselves, they had created gene pools that were necessarily limited to what they had brought with them: only a subset of what was to be found in Africa. This idea had been used to explain, for example, why Africa contained both the tallest and the most diminutive people in the world, and why so many top athletes were African. It wasn't because they were naturally better athletes but because the bell-shaped curve of random genetic variation was wider. — Neal Stephenson

Genetic Variation Quotes By E. O. Wilson

Evolution by natural selection is not an idle hypothesis. The genetic variation on which selection acts is well understood in principle all the way down to the molecular level. — E. O. Wilson

Genetic Variation Quotes By Jo Walton

Elms are dying all over the place, it's Dutch elm disease. [ ... ] It came from America on a load of logs, and it's a fungal disease. That makes it sound even more as if it might be possible to do something. The elms are all one elm, they are clones, that's why they are all succumbing. No natural resistance among the population, because no variation. Twins are clones, too. If you looked at an elm tree you'd never think it was part of all the others. You'd see an elm tree. Same when people look at me now: they see a person, not half a set of twins. — Jo Walton

Genetic Variation Quotes By Stephan Jay Gould

Cultural evolution can proceed so quickly because it operates, as biological evolution does not, in the "Lamarckian" mode - by the inheritance of acquired characters. Whatever one generation learns, it can pass to the next by writing, instruction, inculcation, ritual, tradition, and a host of methods that humans have developed to assure continuity in culture. Darwinian evolution, on the other hand, is an indirect process: genetic variation must first be available to construct an advantageous feature, and natural selection must then preserve it. Since genetic variation arises at random, not preferentially directed toward advantageous features, the Darwinian process works slowly. Cultural evolution is not only rapid; it is also readily reversible because its products are not coded in our genes. — Stephan Jay Gould

Genetic Variation Quotes By Edward O. Wilson

the genes of modern-day Africans are a treasure house for all humanity. They possess our species' greatest reservoir of genetic diversity, of which further study will shed new light on the heredity of the human body and mind. Perhaps the time has come, in light of this and other advances in human genetics, to adopt a new ethic of racial and hereditary variation, one that places value on the whole of diversity rather than on the differences composing the diversity. It would give proper measure to our species' genetic variation as an asset, prized for the adaptability it provides all of us during an increasingly uncertain future. Humanity is strengthened by a broad portfolio of genes that can generate new talents, additional resistance to diseases, and perhaps even new ways of seeing reality. For scientific as well as for moral reasons, we should learn to promote human biological diversity for its own sake instead of using it to justify prejudice and conflict. — Edward O. Wilson

Genetic Variation Quotes By Ben Aaronovitch

Perhaps, I thought, the dead god gets folded into the existence of the new god, the way a dormant genetic variation can exist within an organism's DNA - hanging about like an actor's understudy until the right environmental conditions give it expression and - hey presto - suddenly a bacteria is heat resistant, our Chloe gets her big break on Broadway and a sniper for hire gets an unexpected half a meter of cold steel through the chest. Perhaps — Ben Aaronovitch
