Now, to see whether you have any arguments beyond the ones copied from creationists pages, could you please try to answer the two other questions as well ? (or at least admit that you don't know if you can't) Airmano Edited by airmano - 15 March 2015 at 12:31am |

Yes. A current favourite of mine is the relatively recent discovery that giraffes are just on the cusp of separating of different species despite *not* having any geographical separation of the diverging sub-species. http://news.bbc.co.uk/1/hi/sci/tech/7156146.stm Chris. |

Chimpanzees did not become humans, any more than humans became chimps. Perhaps you should understand the theory before you criticise it.
If you want the specific laws that relate DNA comparisons to ancestral distance, you can find them on the Internet, but I warn you that they involve some extremely complex mathematics. I'm certainly not qualified to discuss them, nor I suppose are you.
There are many such experiments, but you dismiss them all as being within species. One would not expect direct observation of evolution from one species to another, because that takes millions of years. But as I said, we don't need direct observation of species evolution any more than we need to directly observe your grandfather to know that you are related to your cousins. We have DNA evidence, which is regarded as conclusive beyond any reasonable doubt.
It's not speculation. DNA of chimpanzees and humans have been repeatedly compared in a variety of ways, and all estimates come up with about 2% difference. And as I keep saying, common ancestry is measured by DNA difference.
Now that is mere speculation.
You complain about lack of experimental evidence, and yet you postulate Intelligent Design??
You should probably read Darwin's Origin of Species. Darwin made decades of observation before formulating the theory.
No case is ever 100% perfect, but the fossil evidence is quite strong enough to make the case satisfactorily to any fair-minded individual. What I was saying is that you will never accept the evidence because there will always be gaps, albeit smaller and smaller gaps. Anyway, I'm not discussing fossil evidence here. The case I am making is that the DNA evidence, on its own, tells us that all living things share a common ancestry. We don't even need the fossils.
And yet law courts accept DNA evidence as conclusive beyond any reasonable doubt. I'm not sure what kind of experimental evidence you want. Human DNA produces human beings; chimp DNA produces chimpanzees. You want somebody to create an intermediate creature by blending the two genomes somehow? It might be possible to do, but would it be ethical? And what would it prove anyway?
Maybe no advantages that are apparent to you, but they make perfect sense to me. Music, art and religion all play roles in social bonding and group identification. The ability to ponder the nature of the universe is fundamental to science, and is probably the ultimate survival advantage. |

I am an artist. Give me a pen, paper, and enough time and I can create anything. I'm not saying it will look spectacular; but the only limit to what I can do with these tools is my imagination. I have a definite style when I draw, it is evident in all I do, fundamentally my work usually looks similar, yet at the same time no two drawings will ever be identical. Now the purpose of my ramblings here are simple. I believe that God is an artist as well (check out any sunset or rainbow... the things he can paint with a little bit of light and some water vapor is amazing). God has his set of tools that he works with... the elements, and with them he can create anything. He has a definite style, and while some things make look similar to others, no two creations are identical. Because the things around us and we ourselves are made of similar elements and have many traits and features in common... right down to our DNA, does not prove or even necessarily mean we evolved from some sort of primordial pool of soup. The way I see it is simple. Evolution is all about chance. Creationism is all about design. To some the evidence put forward at the start of this thread seems to prove evolution. To me it just proves there was one amazing artist behind it all. Always sincere... sometimes serious John B |

Hey Quranexplorer (or anyone),
I'm curious to know what you think of a study like this: DNA study shows Celts are not a unique genetic group It's exactly the same kind of analysis that measures the genetic distance between us and other primates. If it's valid for identifying tribal relationships, then why not species relationships? Or if it's not valid, then why is it considered valid for immediate families and distant cousins? |

It shows that increasing scientific knowledge can overturn things previously accepted as truth. (Including earlier scientific findings, if necessary, in the light of new information or better techniques!) The "Celtic fringe" as a unity is shown to be more mythic and less historical, an "everybody knows" which turns out to be less true than popularly believed, but I absolutely adore the detail that Devonians and the Cornish have viewed each other with distinct suspicion from their relative banks of the Tamar for millennia, not just centuries. Science is trumps. Chris (I type this from Cornwall) |

Welcome to the forum, John! (Can I call you John? )
Is that what you would tell a judge in a paternity suit? "Just because my DNA matches closely with the child's, that does not prove we are related. It's just that the Creator has a certain style, and His creations tend to look similar." I don't think he'd buy it. No, you're missing the point. My DNA is something like 99.999% (don't quote me!) similar to my sister's. That is clear evidence that we have a common ancestor, and gives a good indication of how many generations ago -- just one in this case. My DNA is also something like 99.9% (again, don't quote me!) similar to yours. That is clear evidence that we also have a common ancestor (about 50,000 years ago, IIRC). My DNA is also about 98% similar to a chimpanzee. Why is this not equally strong evidence of common ancestry, estimated to be about ten million years ago?
Actually, evolution is all about natural selection, which is the opposite of chance. |
