You would think that UV just causes mutations, but it doesn't; you need a gene to be active for it.
Mutations can arise anywhere in the genome, in gene DNA and noncoding DNA alike. But mutations to genes have bigger consequences: They can disable proteins and kill a creature.
All human beings are, in fact, born with dozens of mutations their parents lacked, and a few of those mutations could well be lethal if we didn't have two copies of every gene, so one can pick up the slack if the other malfunctions.
Tobacco, UV rays, viruses, heredity, and age are the main causes of cancer.
There's already a lot of active research going on using the Crispr technology to fix diseases like Duchenne muscular dystrophy or cystic fibrosis or Huntington's disease. They're all diseases that have known genetic causes, and we now have the technology that can repair those mutations to provide, we hope, patients with a normal life.
We add that it would be all too easy to object that mutations have no evolutionary effect because they are eliminated by natural selection. Lethal mutations (the worst kind) are effectively eliminated, but others persist as alleles. ...Mutants are present within every population, from bacteria to man. There can be no doubt about it. But for the evolutionist, the essential lies elsewhere: in the fact that mutations do not coincide with evolution.
Fundamentalism in most of its forms is the active creation of antibodies to some threatening [god] virus. As long as threatening religions or mutations [heresies] are present, fundamentalism will churn out antibodies to keep the population under control and prevent mutations from getting out of hand.
My idea right from the beginning, I guess, was to dismantle the immune system one gene at a time so we could track the mutations that cause problems.
It is probably fair to estimate the frequency of a majority of mutations, in higher organisms, between one in ten thousand and one in a million per gene per generation.
UV is bad for molecules because its high energy breaks the bonds between a molecule's constituent atoms. That's why UV is bad for you, too: it's always best to avoid things that decompose the molecules of your flesh.
After observing mutations in fruit flies for many years, Professes Goldschmidt fell into despair. The changes, he lamented, were so hopelessly micro [insignificant] that if a thousand mutations were combined in one specimen, there would still be no new species.
A gene might be able to assist replicas of itself that are sitting in other bodies. If so, this would appear as individual altruism but it would be brought about by gene selfishness.
What would happen if the autism gene was eliminated from the gene pool? You would have a bunch of people standing around in a cave, chatting and socializing and not getting anything done.
If life really depends on each gene being as unique as it appears to be, then it is too unique to come into being by chance mutations.
I don't suffer from SCD myself, but I do carry the gene. This means that if I married another person who carried the gene, there would be a danger our children would suffer from the disease.
When we talk about genes for anything, like a gene for being gay or a gene for being aggressive or something of that sort, that a gene for anything may not have been a gene for that thing under different environmental conditions.
