If evolution is real how come things aren't evolving now?
babygirl8732: I hope you realise that the bible isn't really very convincing as evidence unless you already believe it. Not to mention, calling people "shallow" based on your belief is a bit, um - shallow?
Also, I'm sorry to inform you that reality contradicts your book. The earth isn't flat, and evolution does happen. We can observe it happening. The only argument is as to the exact mechanisms, and if you want to deny evolution, you're going to have to explain how well-understood things like bacterial antibiotic resistance, viral mutations (such as in Flu and HIV virii) and subspecies adaptation - not to mention the fossil record.
You'll also find that a lot of other christians don't take your literal view of the bible. The catholic church, for example, has explicitly stated that evolution does not conflict with the catholic faith.
They are. If you want to see proof of multi-mutation evolution, you just have to examine the evolution of HIV within a particular individual, which is observed over the course of about 10 years in the absense of anti-viral meds.
The reason the disease eventually takes over, is because it evolves to combat a particular person's immune system, requiring about a half dozen mutations. Each one of those mutations makes the virus only slightly more effective at reproduction within the given person's immune system. Anti-viral meds reduce the overall number of viruses within a person, reducing opportunities for beneficial (to the virus, not to the person) mutations, and thus slowing down the progression of HIV to AIDS.
This has been proven using DNA sequencing. This is not speculation.
I don't believe the question is whether or not evolution can occur through natural selection, and variance as the driving force. Mutations occur quite frequently in a genome, and make this variance possible. My question is the mathematical probability of random mutaions in the genome of a single cell bacteria or organism occuring enough to leading to the complexity that we see today no matter how many billions of years, especially when dealing with certain cells which are specialized and some which are not. Also the mere thought of endosymbiosis occuring (an even greater random event) is baffling even to a biologists. P.S. I am a biologists.
papajon: "My question is the mathematical probability of random mutaions in the genome of a single cell bacteria or organism occuring enough to leading to the complexity that we see today no matter how many billions of years"
What is the problem with that? Your statement "no matter how many billions of years" implies that you don't think small cumulative beneficial mutations can result in what we see today - not a mathematical argument based on probability, you seem to be claiming that it's not possible at all.
Why do you think this is so? Do you have any evidence to that effect?
they are. its takes thousands and MILLIONS of years for something to eveolve so long in fact, that you probably wont get to see anything evolve in your time because it doesnt just happen in a ytear or something if thats what your thinking ...thousands and MILLIONS of years thats how much time it takes for something to evolve and adapt to its changing enviroment
Sure we are all evolving now - rather, our populations are evolving. And evolution isn't always a slow process - sometimes it happens rather quickly. It's not too hard to find the studies if you really want to read up on it. Google is your friend.
things are evolving but evolution takes millions of years. thats like asking why you didnt see a piece of grass growing when you looked at it for five minutes. the grass must not be growing right?
Here's a fascinating example of evolution observed in the lab recently, where a bacteria evolved an entirely new capability: http://scienceblogs.com/loom/2008/06/02/anewstepinevolution.php
Things are evolving now and you must remember evolution takes millions of years so changes are VERY gradual. I believe that it is a correct theory.

Questions like this go hand in hand with questions like "How come clouds don't fall down?" Just because we can't see it happening doesn't mean it isn't.
yeah what happend... I thought guys were sapost to get smarter! lol I really dont care about evolution
Things are evolving now, it just takes a looong time for it to happen.
I just hate how stupid some people are... and love it...
Things ARE evolving now. Just too slowly to notice.
