In genetic mutation no beneficial mutation has ever been recorded that benefits that life form it's self?

Question

I am not talking Virus or Bacteria lol Me thinks people mis understand on purpose.

There have been NO beneficial mutations. Not one of you have given any as yet. You just give variations.

I still love you for answering though. In my own special way.

lol pam he he

sci. Evolution is flawed, we should not ignore it.

We should ask questions

Sickle cell is not beneficial if you have ever known or experienced it. This awful condition leads to pain and often early death. The fact it gives the person immunity from malaria is because it's loss not gain.

Answer 1

Evolution takes many generations to occur.

Since you are ruling out every living creature with a lifespan short enough for humans to witness many generations first-hand, how can you seriously expect to see evolution occur?

Bacteria are alive. Evolution has been proved to occur with them. It is completely unreasonable to pretend that it doesn't occur in humans as well.

Answer 2

That is actually a false statement. And antibiotic resistant bacteria are obviously examples that are easily able to show this - so why are you ignoring that data?

The majority of the population of humans in the Americas, Europe, Africa and Asia now carry genetic mutations that make it possible for them to survive influenza for example. The ones who did not have this beneficial mutation that created a set of genes to produce antibodies against that illness, have mostly died out and have not passed on their genetic material to successive generations. Influenza has continued to mutate and change it's methods for invading a host organism however, and as a consequence we are still able to contract new strains but we tend to be better equipped to survive these new variants than isolated populations whom have not been exposed to the disease. Only when a disease develops a variant that can survive in a new host species do we see huge epidemics like the new "Bird Flu"...

Ignore the facts if you wish - that is not called being ignorant, it's just denial. But it seems pointless to me -- why bother to ask a question if you don't want a meaningful answer.

Answer 3

Sickle Cell Anemia. A genetic "defect" that we consider bad. Unless you look at where it is common, in areas where malaria is common, then having sickle cell makes you much more resistant to malaria. In that case, it is a genetic mutation that does benefit the individual.

Going a bit further, being BLACK in a very northern region like Sweden is not so good as you do make enough vitamin D. Being WHITE in Africa is not so good as you get skin cancer much more often.

When you talk about genetic mutation, you have to look at the area where it first showed up to determine if it was a benefit or not.

Answer 4

I see you are still insisting on the same... "field"
I agree about sickle cell disease: the reality is HbSS does NOT protect against Malharia. You can ask any department of haematology how many patients with SCD go back to see their families in Africa and how they have to be on antibiotics to prevent the acquisition of the protozoal.
I think there's an overall problem with the concept of evolution. Mutations are NOT INTENTIONAL, and they have NO PURPOSE.
I am happy to discuss this with you. It is... my field.

Answer 5

I don't know if I follow your question.

But Giraffe's with longer necks were able to eat more available food and lived long enough to procreate and pass on that mutation, which the shorties died of starvation.

That seems like a pretty darn good benefit!

Answer 6

So...the fact that there HAVE been recorded positive genetic mutations in bacteria and viruses contradicts your presupposed thoughts, so "they don't count"? How wonderfully non-scientific of you.

(P.S. the original premise of your question is incorrect, I recommend you read more about evolutionary theory.)

Answer 7

Of course. Darwin's moths are an example; the change in color from mutation reduced their tendency to become bird food.

Answer 8

Variations ARE mutations.

Besides, we're only still here because our crops adapted to the places in which we grow them.

Answer 9

I don't know of any either. Giraffes need long necks because they can't reach water on the ground to drink because their legs are too long. Moths that didn't blend in were eaten leaving only those moths that did blend in. Both were around at the same time.

Cheers :-)

Answer 10

Oh dear, it's troll time again.

And it is beneficial for the bacteria that survive.
