Omicronâs Radical Evolution* Thirteen of Omicronâs mutations should have hurt the variantâs chances of survival. Instead, they worked together to make it thrive.
The rules of inheritance are supposedly easy. Dadâs DNA mixes with momâs to generate a new combination. Over time, random mutations will give some individuals better adaptability to the environment. The mutations are selected through generations, and the species becomes stronger. much more
Good morning indeed...I'm already exhausted reading this... So...let's just say they're right, and that the same thing happens in humans. Then, let's assume in a few generations, a really nasty form of COVID comes along, and only those who have been vaccinating (grandparents, parents, individuals) will have the trained epigenetic coding to respond to the "really bad strain"... is it possible we could "breed out" the anti-vaccers? Kids...pick your reproductive partners well!
the precise answer is definitely possibly maybe or theoretically it looks like it if we squint a bit (of course the original article is behind a paywall) seriously, we're finding out more and more regarding epigenetics short answer is that we have a lot of code/dna and we pass it on that code has an on/off function it looks like that certain immune code that gets turned on can be passed on to offspring in the on position biotech is in the early stages of exponential-like discovery writing or modifying biological code has huge potential we'll see what happens and where it goes.. i encourage people to use a platform like twitter to aggregate this type of news most of these companies have a feed to glean for their projects

The rules of inheritance are supposedly easy. Dad’s DNA mixes with mom’s to generate a new combination. Over time, random mutations will give some individuals better adaptability to the environment. The mutations are selected through generations, and the species becomes stronger.
But what if that central dogma is only part of the picture?
A new study in Nature Immunology is ruffling feathers in that it re-contextualizes evolution. Mice infected with a non-lethal dose of bacteria, once recovered, can pass on a turbo-boosted immune system to their kids and grandkids—all without changing any DNA sequences. The trick seems to be epigenetic changes—that is, how genes are turned on or off—in their sperm. In other words, compared to millennia of evolution, there’s a faster route for a species to thrive. For any individual, it’s possible to gain survivability and adaptability in a single lifetime, and those changes can be passed on to offspring.
“We wanted to test if we could observe the inheritance of some traits to subsequent generations, let’s say independent of natural selection,” said study author Dr. Jorge Dominguez-Andres at Radboud University Nijmegen Centre.
“The existence of epigenetic heredity is of paramount biological relevance, but the extent to which it happens in mammals remains largely unknown,” said Drs. Paola de Candia at the IRCCS MultiMedica, Milan, and Giuseppe Matarese at the Treg Cell Lab, Dipartimento di Medicina Molecolare e Biotecnologie Mediche at the Università degli Studi di Napoli in Naples, who were not involved in the study. “Their work is a big conceptual leap.”
How Humans Lost Their Tails A new study suggests that a single genetic mutation helps explain why monkeys have tails, while apes and people do not.
For half a billion years or so, our ancestors sprouted tails. As fish, they used their tails to swim through the Cambrian seas. Much later, when they evolved into primates, their tails helped them stay balanced as they raced from branch to branch through Eocene jungles. But then, roughly 25 million years ago, the tails disappeared.
For living species, John Damuth, a biologist at the University of California, Santa Barbara, came up with a mathematical relationship, now known as Damuthâs law, between the average body mass of an animal and its expected population density.
The relationship is not universal but generally holds for large classes of animals like lizards or meat-eating mammals. So, for Tyrannosaurus rex, they had to not only plug in the weight of the dinosaur â about six tons, give or take a few â but also derive other numbers in the law.
Mention of Charles Darwin, for most, conjures up images of intrepid Victorian sea voyages, giant tortoises and Galapagos finches. Few of us associate Darwin with plant sex. That honor tends to go to his grandfather, Erasmus Darwin, who wrote erotic poems on the topic.
Although Darwinâs On the Origin of Species, which describes his theory of evolution by natural selection, has eclipsed all his other research, his career continued for over two decades after the landmark workâs publication. Much of the aging naturalistâs time was spent studying botany, and his research produced discoveries that, had he not become famous for natural selection, would have made him a well-known botanist.
