Lol do you read the article, it's still on early stage. The evolution theory it's one of many way to learn the virus, but it's still not a practical until now, not until the research are done. And dont forget it's one of many way from many choices. 

What? It's not a choice, either evolution is true or it's not. And research shows that evolution is much more plausible than anything else.

There are multiple types of Flu strains, every year researchers take note of the evolutionary changes in various strains and will then try and predict which strains will become more promonent during the next Flu season and counteract that with their vaccine.

But because there is a chance they might get it wrong... They build the vaccine to combat multiple prominent strains of the Flu.

We also take advantage of evolution and more specifically natural selection to breed-in and breed-out certain traits in plants, cats, dogs and other animals, the traits could be behavioural, could be size, could be colour... Doesn't matter. We use evolution to our advantage.

lol they still doing the research and is only one article claim LOL . The virus it self is hard to research because it has short life span 

That's not what the article says.

What the article says is that a great deal of modern medical research is based on the theory of evolution by natural selection.  Evolutionary science has helped develop tests for genetic diseases, models to predict flu strains, and so on.

What the article says is in the early stage is the direct teaching of evolution.  Even if the findings are not directly taught, that doesn't mean the ideas are not applicable.  The tests and procedures that doctors do is the application of the theory.  Whether or not doctors know that the flu vaccine they're giving is based on evolutionary models does not change the fact that they are applying the findings of evolution.  

These people do not understand the basic principles of science, and what's worse they refuse to learn them. You're wasting your time trying to convince anyone who has taken the time to "do research" when in reality, all they've done is tried to find sources to back up the conclusion they want to be right, rather than studying the actual scientific research and drawn their own conclusion.

These people want to believe that science was right about electricity, automobiles, space shuttles, etc. but completely dropped the ball on evolution because that's a part of science that contradicts their faith because their faith can't possibly be wrong. There's no point in arguing because they're not listening.

Evolution is science , we admited that, but it's not scientifict fact , it's still a theory , because only one part of evolution theory that really help , which is animal kingdom, the rest are still bogus . 

Do you know what a scientific theory is?

https://en.wikipedia.org/wiki/Scientific_theory

do you know scientifict evidence is https://en.wikipedia.org/wiki/Scientific_evidence

Yes, it says that supports a scientific theory. So yes, evolution is a scientific theory with scientific evidence.
