And you are still talking about abiogenesis and not evolution. You can believe that God, chemical soup, aliens or whatever you like resulted in the first life form on earth, but after that, I can show you common descent for every organism.
Hey, look! Hundreds of transitional forms!Quote:

Also I'am not interested in your websites I want to here the argument from you.
I also have no interest in aliens or chemical soup. Only the truth.
just a question how many classes have you taken on this subject?
another question do you believe the punctuated equilibrium?
It surprises me how heated these debates become (after I post this it will be the 1713th reply in this topic). If we could truly accept the fact that some people believe in God and Creation while others believe in "Evolution" why would we have to incessantly debate on the matter? I've seen some eloquently written posts in this thread, some of which have progressively strong points to support their opinions, but it appears (to me at least) outright ridiculous to go on back and forth, back and forth on which view appears more plausible. I personally believe in both creation and evolution... I believe Providence created the creatures which encompassed the earth and evolution biologically tweaked God's creatures to adapt with capricious environmental changes (Giraffe neck growth over centuries and land turtles to armadillos for an example..)
I don't know how it began. Neither does anybody. It doesn't matter, because it happens.Quote:

This is nothing but a way to side step the fact that there are no true transitional forms.
However,it matters greatly how it began. This is the whole question of the matter. You stated that you do not know, neither does evolution. It only provides more questions,not awnsers.I want to give ya some more quotes.
This is by Thomas Henery Huxley, an accredited scientist," If the hypothesis of evolution be true,living matter must have originated from non-living matter
for,by that hypothesis, the conditions on the globe were at one time such that living matter could not have existed, life being entirely incompatible with the gaseous state."
Lorande Woodruff (Biology, Yale University) states it thus:" We thus reach the general conclusion that, so far as observation and experimentation are concerned, no form of life exists today except from pre-existing life."
I have two other problems for ya.(1 What about the plant life? There are no signs of evolutionary, or otherwise.C.A. Arnold said this," As yet we have not been able to trace the phylogenetic history of a single group of modern plants from its beginning to the present."
Also what about you "simularity equals connection" hypothesis? Take for instance Eohippus or "dawn horse," the linage runs thus from "dawn horse" to "modern horse," goes like this, Eohippus had 18 pairs of ribs, but its supposed descendant Orohippus had only 15 pairs;a later stage in the "tree,"
Pliohippus, had 19 pairs of ribs, while the modern horse has 18 pairs of ribs. Such jumping back and forth, with ribs disappearing and reappearing like magic, is a strong indication that the "horse series" is actually a collection of unrelated mammals that share a smiliar overall body plan.
Somewhat like your human,ape, E. coli.
Observation. We can see observe animals that have experienced sudden, drastic, environmental changes and the ensuing speciation. For example, we can compare those organisms on volcanic islands with those on continental islands. The organisms on volcanic islands, who would've had to wind up there by accident, can be shown to have diverged greatly from their ancestors because of the difference between the continental environment and the sea-locked environment. Species on continental islands, however, are relatively close in physiology and genetics to their ancestors, because a continental island's environment doesn't change much when it seperates from the mainland. Check out the differences in the animal populations between, say, Vancouver Island and Hawaii.Quote:

An illustration: most evolutionary biologists assume that abiogenesis occured because the conditions on early earth were such that self-replicating organic molecules were formed which, over the course of millions of years, evolved into the first cells. Suppose, however, the hypothesis suggested by the film Mission to Mars was shown to be correct, and the first organisms on earth were actually put there my martian scientists. Modern biologists would certainly be surprised, but would they have to throw out their taxonomy tree? No, of course not, because the fact that organisms evolve and speciate through the process of natural selection does not depend on the current assumtion of abiogenesis from self-replicating organic molecules.
Another illustration: the theory of gravity is, to put it one way, generally accepted among physicists. How gravity actually works, however, is deeply mysterious. The best current hypothesis, in my limited understanding, is Loop Quantum Gravity which, if you try to understand it, will give you a raging headache. There are numerous competing hypotheses for the mechanics of gravity, however, and nothing is difinitely settled as to how gravitation actually takes place. This does not, however, change the fact that whenever you drop an object it travels at a certain number of meters per second per second towards the centre of the earth until somehow impeded.
Incompleteness is not proof of defect for the theory of gravity, and it is not proof of defect for the theory of evolution.
Well he may be an accredited scientist, but I hope he's not a biologist, because evolution is a theory, not a hypothesis, and it does not depend on abiogenesis.Quote:

What makes you think I haven't studied the Bible?
There isn't any where in the world that you can observe animals in speciation you can only speculate that it happened that way, no proof. That is merely
an example of natural selection. ALSO THE BEGINING IS VERY IMPORTANT,ELSE YOU HAVE NO SUPPORT THAT YOUR HYPOTHESIS IS EVEN CREDIBLE!!!
I didn't say you didn't study the Bible, I said if you don't believe it.
Yes, we can. We observed the speciation of the HIV. You may have heard something about it in the news.Quote:
