Originally posted by Big MacWhile studying the genetics of the evening primrose, Oenothera lamarckiana, de Vries (1905) found an unusual variant among his plants. O. lamarckiana has a chromosome number of 2N = 14. The variant had a chromosome number of 2N = 28. He found that he was unable to breed this variant with O. lamarckiana. He named this new species O. gigas.
honestly and truly for my sake and understanding...
what "new species'" appearance has been "observed?"
no antagonism meant here.

Here's another source for the same event:
4) SYMPATRIC SPECIATION IN PLANTS: AUTOPOLYPLOIDY
•Doubling of chromosome number in germline cell à tetraploid gametes
•Interbreeding between tetraploid gametes in species à self-fertile tetraploid progeny
•Barrier to gene flow can be established in single generation
•Can result from mitotic nondisjunction or meiotic nondisjunction
•E.g.: evening primroses Oenothera gigas (2N = 28), parental species O. lamarckiana (2N = 14); commercial tobacco, horticultutal strains of snapdragon

Now I think about it now and then, but basically it isn't something
I'm overly worried or concern about. Heaven is just a place, the
great reward for Christians isn't Heaven it is God, He has not
made anything greater. He also isn't someone we have to wait
for either, since through Jesus Christ our relationship with God
can start here and now. The distraction of this world can get in
the way, the griefs, the joys, toys, pain are just a part of this
life, but there is someone that is beyond them all here and
now.

woes would be healed either. You want power to make the bad things
go away, you are playing with magic not God. God said we would
have troubles in this life, but that He'd see us through them and
would never leave us or forsake us. When it rains outside everyone
gets wet, the good the bad it doesn't matter, so if you believe or not
in God it doesn't mean that you will be saved from getting wet or
going through bad things, and having a relationship with God also
does not mean that pain and suffer will not be apart of your life
while your here either. The difference is God seeing us through no
matter what comes, some can rest in God no matter what is coming
their way others are on their own and if they cannot save themselves
they end where the strenght and power fails them.

We have over 1,000 awesome posts!
I'm still praying for all of you...always will.
No, that's not "tacky" that's a fact.
Never had took up the idea of evolution. Really, if evolution were true, then why are
there creatures, people, etc. that are stagnet?
If evolution were true, we all would be evolving every day.
No, it's not the same as growing up.
If we were evolving we get a new eye, another finger, a wing, etc.
Nope, just think that Darwin and co. were completely off their rockers.

I'm willing to throw myself into the category of only knowing a fraction of what there is to know about evolution as well.

No creatures today are stagnant. Evolution just moves at a very slow pace. You see plenty of things with a very short lifespan evolving all the time, bacteria for example. Evolution works in terms of generations, not years. So when something has a new generation eveyr half hour, it evolves much faster than something that has a new generation every 20 years. And it works in baby steps basically. You don't suddenly grow eyes where you didn't have any. You get some light sensitive cells and then every once in a while, something happens around these cells to make them confer a larger advantage.
Look at it this way, Evolution managed to go from being believed by a very few number of people, to being accepted almost universally among the scientific community. It seems that almost all the people who take the time to really learn about the evidence and mechanisms of evolution ends up believing it; while those who just say "There is no way I am decended from an ape" look no deeper and continue believing in creationism. I have read the bible cover to cover (I'm not religious). I think if you want to keep insisting on arguing about evolution, you should have the same courtesy and learn a bit about it. I would recomend The Blind Watchmaker by Richard Dawkins. It isn't too heavy of a read, is one of the most informative books I've ever read, and is a heck of a lot shorter than the bible.

Originally posted by scottishinnzProbably not, but I figure if I keep recomending it to people, maybe someone, sooner or later, will actually bother to read part of it, or any other good evolution book. Then even if they don't change their mind, someone can argue about it from a more educated point of view.

I personnally think some basket cases are beyond repair.
Originally posted by UmbrageOfSnowIt sounds like you're indirectly saying you are an expert on evolution.
