Subject: Darwinian evolution.

So as far as evolution is concerned, through mutation, can this frog inseminate some frog eggs that will have six eyes? Or would it require both a male and female breeding to produce like offspring?

That's a man-made definition of what we mean by 'species'. We arbitrary used that distinction to define this term.

So if you take a group of a single species and slit that group up on two isolated islands for a long enough period of time they will eventually diverge to the point where the two groups will no longer be able to procreate viable offspring.

Then you are justified in stating that they are no longer the same species.

Precisely how many generations that will take to achieve is something that a geneticist might be able to answer.

Obviously you'll have far better luck using species that procreate quickly and die quickly. That way you can observe many generations over a short period of time.

If you use elephants for your experiment you probably won't live long enough to see any change. I think a single generation for an elephant is longer than a human lifespan.

So better off using fruit flies or something like that.

In fact, I think there have been biological experiments where this has actually been achieved. But arguments then arose concerning whether or not they had actually created a new "Species".

Let's not forget that the very definition of "species" is a man made construct. We simply define "species" based upon an ability to procreate between the same creatures.

That's a totally arbitrary definition and term created by man.

If these fruit flies can no longer breed with those fruit flies does that really mean we have created a new "species"?

They both still LOOK like Fruit flies to me!

Just because they have sexual impotency problems doesn't mean they are a new species!

That's the argument that is given against these kind of experiments.

The whole notion of what it means to be a "species" comes into question.

I totally agree with the concept there and how traits can indeed be controlled by natural selection.

However, in that particular case, the crabs are still just crabs and the ones that have samurai makings on them can probably still breed with crabs of the same species that don't have those markings.

So no "new species" was actually created due to that process.

Evolution: How much change is required to become a new species?

How much change do you think any species would have to go through to cross over from one species to another?

Like fish to a lizard.

I'm not an expert on the new (or even the old) theory.

From wikipedia:

I don't believe that my t.v. has a camera in it, but there is this little red light that's always on, and right under it is this dark square... maybe it is a camera lens... okay, I'm putting some tape over that.

This is a poll.

Do you believe the Bible is historically accurate?

Does your church teach that the Bible is true and historically accurate?

Are all the stories set out and told in the Bible true or are they fiction or a mixture of both?

then i saw a show with justin tiberlake when he was a small kid his eyes were blue. then they showed him as an adult. his eyes were black.

I was just scanning my FB page and there was a prayer wishing misery and death on someone they felt deserved it

First, off no one can determine another's life or death deservance, period.

But to me this shows an unhealthy mind, one that feels justified in determining whether another human deserves this life.

Who are they to feel they have this right?

Beautiful, young American women keep hitting on me, and yet I get almost no responses from Canadian women that I'm attracted to. Are Canadian ladies in so much demand that they won't even respond without a ton of courting first, or are these American women fishing for a rich sucker?

...I've often wondered if we free-software proponents shouldn't take a hint from Microsoft and charge US$300 for Linux, in the hopes that people will then pirate it.

What will make us feel younger at our age? ... I think that finding the perfect mate will do the trick. Give us someone to look forward to seeing every morning. Instead of looking at ourselves as a me... look at it as we! There is so much out there to see and do, other then growing old and being alone, and bored to death! What works with others that are over 50?
