I have some questions for you...
Why do organisms adapt and change, in your opinion? What is the mechanism by which this happens? Is it through generational mutation, or something else?
I believe that all of God's creatures are designed to survive changing environments and to adapt to new food sources by the mechanisms that are programmed into them. Like instinct, it is not something consciously achieved by the creature...it is simply designed to survive without his direct intervention. These changes are apparently brought about by circumstances that trigger the adaptation.
Like the Chinese adapting to lactose now that they have discovered dairy products. The Chinese until very recently were lactose intolerant but by eating more dairy products and feeding their children on milk based formula, we can see that the tolerance is built up over time.
Darwin's finches too adapted to different food sources which resulted in a change in the shape of their beaks and over time the ones with a longer beak survived when those with shorter beaks died out.
The Peppered Moth is another example of survival. Changing color from light to dark when the trees changed color from the coal fires, this made the dark ones less of a target so they survived better than the lighter colored ones.....and then when the pollution problem that had caused the moths to adapt was remedied, the moths went back to their original color. Adaptation was never going to change one creature into another, no matter how much time elapsed.
In all instances we never saw any of them step outside of their taxonomic families....all that happened is that new varieties were created by necessity within their kind....with the survival of the species never threatened.
Why do you think that changes will be limited to the confines of what parameters exist inside of a given "family" group? What is the mechanism that prevents organisms from changing beyond that?
Because I see natural genetic roadblocks in place to prevent one "kind" from breeding with another "kind".
Horses and donkeys can produce mules....but the mules are invariably sterile. Both are equines. (same family)
Lions and tigers can interbreed but their offspring too are invariably sterile, yet both are felines.
No matter what, members of the animal kingdom are programmed to breed exclusively within their own kind.....and even within their own species. The aforementioned examples are the product of artificial breeding...something that would never take place in the wild.
In oceans full of fish, we never see one species turning into a completely unrelated one through adaptation. And I am certain that little old Pakicetus was never a whale.
Where can we see adaptations taking creatures out of their taxonomy? This is what evolution basically teaches....amoebas to dinosaurs.....that is rubbish science. It has no foundation whatsoever. It is a "belief"...just like I have.
If given enough time (let's say an infinite amount of time), do you think these changes could possibly allow an animal to change so much that they could fall outside of the confines of what the "family" group is identified by? Why or why not?
They are programmed by a Creator who has demonstrated that all the kinds he created, stay in the same family....no matter what adaptations take place.
There is no cross over...nor has anyone ever produced a "common ancestor" to prove that one kind can branch out to transform into another unrelated kind.
IMO, saying that amoebas can become dinosaurs in a few million years, is a fairy story.....more based on imagination, than fact.
Is this your 'go to' when you have no answers....? If you don't know what to say, then please don't make excuses for why you can't respond....what makes you think I haven't talked to all of those supposedly smart people?
