Green_Manelishi:Do you know the barrier does not exist of do you refuse to believe that it exists?
no, i require proof of you that it does exist. you claim that there's a barrier there, so show me it.
Have you actually seen the shift into other orders and classes or do you believe it must have occured?
of course i haven't seen it occur with my own eyes. yes, it is extrapolation. extrapolation is actually different than faith and has a pretty decent track record in science. you need to prove that the extrapolation is invalid. i ask a very simple question which is to show me where the barrier occurs.
Your argument is circular: the fossil records show it occured and it occured because fossil records show it occured. Your "science" is faith.
your understanding of a circular argument is poor.
You assume the fossil record is somehow chronoligical despite no direct observation. You also assume your dating methods are infallible. How do you date the fossils? By the age of the rocks? Do you date the rocks by the alleged age of the fossils?
radioisotope dating (which goes well beyond radiocarbon dating) is widely useful. it has been used, for example, to date the age of the moon and to show that the moon was formed by crust material from the earth which was ejected due to an impact and to date the time of the impact. similar techniques can be used to date rocks on earth. those dates are consistant with the age of the Sun calculated from stellar models, which relies on stellar nucleosynthesis and fusion physics rather than radioactive decay models, and thereby validates the range of dates generated from radioisotope studies. and if all the methods of radioisotope dating are wrong you would have pretty much overthrown just about everything we know about nuclear physics.
so, no, i don't assume the dating methods are infallable. and nobody would use fossils to date rocks to date fossils.
Here's another question; statistically, what is the probability of a fully viable human female evolving concurrently to a fully viable human male? "Well it must have happened because ..." is not a scientific answer. And that's only once example of the insanity of your "science".
that's got to be some of the best evidence yet that you don't really understand evolutionary theory at all.
Continue to believe that you are refined primordial soup; it's your choice.
show me the inherant barrier to speciation in evolution. show me the clothes the emperor is wearing.
