  Looking for evolutionary info on how smells can be carried on DNA

  by Crabby in

  as i said last night the smell of pus from an infection is recognized by all puppies without their being exposed to the smell previously, this is shown because all puppies react the same way to this smell, which is to lick the infected pus laden wound.. this demonstrates that smells are carried on dna in some way.

  any thoughts on how?.

  cofty my children are adults, you have no clue as to anything

  So why are behaving like a petulant child?

  Neither the article nor your book has any idea how the information is passed, you do not even know what epigenetics means. - Crabs

  The book I suggested describes the process of methylation and epigenetics in detail right down to the molecular level. I understand what is currently known about epigenetics, Why would you assert otherwise?

  You give the impression of being pre-teen or early teens. Do you have mixed feelings about being disloyal to the religion of your parents? Is that why you are angry and insulting to other adults?

  anyone else also hold this view or understand it at least, or do you feel the need to argue that both can in no way coexist?.

  Crabs - For the third time what is your interest in an ex-JW forum?

  Does mummy and daddy still make you sit still at the kingdom hall?

  Crabs - The SA article contains the same answer I gave you. Epigenetics. Did you even bother to read your own source?

  I've answered your question - Methylation aka epigenetics.

  Read a book

  Crabs - your posts so far suggest you should not be criticising anybody's intelligence.

  What is your interest in an ex-JW forum?

  how does the DNA carry a smell which is not part of the body from one generation to the next - Crabs

  First you need to provide evidence that it does. I have serious doubts. Please link to a source.

  Experiences can have an effect on future generations through a process called methylation. It is like a temporary switch that regulates the expression of genes.

  Trust me, there is no book that you can read that answers this question - Crabs

  I don;t trust you at all. Methylation is described in lots of books and hundreds of papers. You could start with "The Epigenetics Revolution" by Nessa Carey

  Our brains are built by genes. Our instincts are hard wired by genetic switches. We avoid dangerous heights, snakes, things that roar, shagging our relatives, eating shit and things that smell of puss because genes wired our brains that way.

  Would you like some book suggestions?

  Crabby are you even aware that most of the people on this forum left the cult years ago.

  Some of us have been reading science for 20 years.

  You have no introduction. Who are you? Are your mummy and daddy JWs? Do they make you go to meetings and sit still?

  The rule in gene survival is "use it or lose it".
  

  When a gene ceases to be useful, mutations are likely to accumulate as they are passed on down the generations. These broken genes are called pseudogenes and they provide powerful clues to our evolutionary past.

  Compared with other animals our ability to detect odours is poor, but if evolution is correct there was a time in our distant past when we relied on our sense of smell much more than we do today.

  Our olfactory receptors are coded for by OR genes. Geneticists Linda Black and Richard Axel won the Nobel Prize in 2004 for their work in this field. They discovered that humans have 800 such genes but fully half of these are inactive relics of our past. As our brain combines signals from a number of receptors simultaneously that means our sense of smell is only a fraction of what it once was.

  What though of our closest relatives? Well not surprisingly there was found to be a direct correlation between the closeness of our evolutionary cousins and the number of active and inactive OR genes. We carry this genetic baggage because it was needed in our distant ancestors who relied on a keen sense of smell for survival.

  Clearly a mechanism that enables us to detect airborne odours is not going to work the same under water. In fish we find one kind of OR genes and in amphibians and mammals there is another. So what about aquatic mammals like dolphins? If they really were once land animals as evolution claims, there should still be evidence in their genome that they once had an acute sense of smell.

  Not surprisingly the evidence is irrefutable. 80% of the OR genes in a dolphin are inactivated; hundreds of them remain in their genome as silent testimony to their evolutionary past. Dolphins have the instructions in their genes to construct the tools for detecting thousands of airborne smells. This makes no sense if dolphins were specially created.

  The most primitive fish still alive today is a jawless fish called Lamprey. Fossils of these creatures 320 million years old bear a very close resemblance to it’s modern cousin. When the DNA of the lamprey is studied it turns out their OR genes are neither air nor water specific; they combine features of both. These creatures arose before smelling genes split into two types.

  Like all our other genes our OR genes tell a story of our species’ past. They are very similar to primates, less similar to other mammals, less similar still to reptiles, amphibians and fish in that order..
