If evolution is true, why have we stopped evolving?

Its me again, retaliating to creationists stupid arguments. This is one that comes up momentarily in debates and discussions. "why have we stopped evolving?" I will now arm you on how to respond.

 

First of all, we must understand evolution. Evolution is the change within a specie, due to adaptation of its environment. Precisely why it is documented that people that live in high altitudes literally have bigger hearts.

 

Now there's a simple answer, we did not STOP evolving. Our life spans are way too short to observe the development of species over millions of years. Micro-evolution has been been proven, and is very much observed due to the short time it takes. Now magnifying micro-evolution over millions of years, then evolution has become real. The essence is, if our life span was millions and millions of years, we would indeed see the evolutionary process at work. As long as a specie needs to adapt to its environment, it will continue to evolve.

Lol @booklover. I have a shirt that says " Fine, I evolved....you didn't" LOl stirs up alot of drama on my college campus .

A lot of idiots Haven't evolved yet. ;)  I want that bumper-sticker that says "Evolve Already!" lol

@Ashleigh. The SIMPLEST definition i can think of for a specie is "a group of organisms capable of interbreeding and producing fertile offspring." For example...An alligator and a crocodile are NOT from the same specie as they cannot interbreed to produce fertile offspring.

 

The peppered moth is a GREAT example of evolution due to change in the environment. The earlier peppered moths predominantly had light-colored bodies which enabled them to camouflage against the lichens on trees. After the industrial revolution and the production of soot, the lichens on trees began to die out leaving the trees with a black appearance. Evolution enabled the moths to adapt to their now blackened environment, producing offspring with darker colored bodies. They did not split into 2 different species but adapted to their environment. Remember, survival of the fittest.

When I was a child and heard about evolution for the first time, I think I misunderstood "slight differences" for "slightly less human". I thought that if a woman was human and a man was human and they had a child that was somewhere between mom and dad in makeup, they should be "completely human" and that if evolution were true, that would mean that each successive generation would be "slightly less human", which I suppose is one way to look at it, albeit oversimplified, in that as differences multiply you draw closer to having one species split into two or more. But I grew up with the idea of "kinds" also, so I was stuck in the rut of thinking that a homo sapien is exactly what we have now, no more, no less. Which is really quite silly when you think about it considering the wide range of variation we can have from one person to another. But I also was unaware that the definition of "species" was a group of whatever (technical term) that can produce viable offspring and as a child I had always thought of a species as being animals/plants/things that looked alike. I guess I thought there was a special allowance for males and females of a species that didn't look alike. I don't really remember having discussions about it, but I wouldn't be surprised if that's still the colloquial definition of species which could definitely put a monkey wrench in someone's ability to wrap their brain around evolution. So I guess when it comes up, it might be a good idea to start the conversation off with 'what is your understanding of a "species"?'

Also, about peppered moths, did they split into two separate species or did they just develop more color pattern variation?

Johnsky, I'm not arguing against the grain (for once), but one's children having a different appearance is not due to evolution. It is due to genetic recombination during reproduction. It's one of the (now) built in mechanisms of sexual reproduction that has the effect of aiding diversification. However, if someone is lacking enough familliarity with evolution to claim that it has stopped, then they probably wont know that either.

 

Molars are a good example, Thomas. Vestigial finger webbing and tailbones are some other examples. The ability to wiggle one's ears is another, and goosebumps. They are all traits that are useless to survival now, and are slowly disappearing in humans, but clearly served a purpose to our ancestors.

Most succinct answer:  We haven't; we are still evolving, and as long as our species exists, it will be evolving.

 

NOTE: There is a particular misdefinition that some creationists have in mind for "evolution" which, though I am not familiar with it in explicit detail, indicates that "evolution" means that some dramatic difference (e.g. between those "kinds" that creationists believe in and which creationists mistakenly believe non-creationists to believe in as well) be found between some parents and their offspring such that they are different species--the kind of miraculous event which, curiously, would only indicate divine intervention.

 

If a creationist is (and you must ask them about this to find out) operating under this definition (some do and some do not), then you must make them aware of "evolution" not referring to such a thing.  Of course if they think that that is what evolution is, it is plain to see for them that their "evolution" isn't occuring--trees beget trees, mice mice, humans humans, cats cats, and so on, "after their own kind".  You must make them aware of the fact of their definition for "evolution" being in error in order to get them to understand real stuff.

actually we have not stopped evolving, take the case of the rear molars, more people are being born without them because our diet no longer requires massive grinding of tough plant fiber

Just tell them we haven't.

Ask if they have children.

Ask if they look identical to them in every way shape and form.

 

If they aren't identical twins to their parents... boom... evolution.

It's not a hard bloody concept to grasp.

 

You'd either have to be retarded or a Christian not to comprehend this.

(I still have trouble finding the line between the two.)

The simplest definition of evolution is the change in the gene frequency within a population over time.

That's right, we have'nt stopped evolving and don't forget our species is only one or two hundred thousand years old. It is only about sixty thousand years ago our species left Africa and began populating the world.

We are not talking about 'millions and millions of years.'
