Let's have him try this for size.in the end you still have a dog,,
its called breeding for a reason,, if it were evolution it would be called evolution..
and please stop with the religion deflection,, either evo can stand on its own merits or it cant,,
Yes it does.Selective breeding doesn't demonstrate evolution.
A good way to prove what you say is a series of pictures is worth a thousand words.Who have you asked? Science has never presented the step-by-step changes needed or have you not even bothered to look it up?

Evolutionary changes at the atomic and molecular level primarily involve alterations in DNA nucleotide sequences, which are the building blocks of genes. These changes, known as mutations, can range from single base pair substitutions to large-scale genome rearrangements. Other key molecular mechanisms include recombination, gene conversion, gene duplication, and new gene creation. These changes lead to variations in protein sequences, which in turn can affect their function and structure.
Here's a more detailed look at the key molecular mechanisms:
These molecular changes, driven by mutation, recombination, and other mechanisms, provide the raw material for evolution, and natural selection acts upon these variations to shape the genetic makeup of populations over time.
- Mutations:
Errors during DNA replication, repair, or recombination can introduce changes in the nucleotide sequence. These changes can be subtle, like a single base pair substitution (point mutation), or more extensive, involving deletions, duplications, or inversions of DNA segments.
- Recombination:
The exchange of genetic material between chromosomes during meiosis can lead to new combinations of genes and alleles.
- Gene Conversion:
A process where one DNA sequence is replaced by a similar sequence, often leading to homogenization of gene sequences.
- Gene Duplication:
The creation of extra copies of genes, which can then diverge in function over time.
- New Gene Creation:
In rare cases, entirely new genes can arise through various mechanisms, such as transposon insertion, gene fusion, or other novel mechanisms.
- Protein Evolution:
Changes in gene sequences translate into changes in protein sequences, potentially affecting their function, structure, and interactions. Natural selection can favor proteins with advantageous new functions or structures.
no it doesnt,,Yes it does.
Denied.A good way to prove what you say is a series of pictures is worth a thousand words.
Show us step by step photos for examples. Photos have been around a long time.
Sorry, but you're wrong.no it doesnt,,
You've made my case, all speculation, no definitive roadmap of evolutionary change.Who have you asked? Science has never presented the step-by-step changes needed or have you not even bothered to look it up?

All that's left to know then is exactly how, step by step.Given enough generations ... then yes ... selective breeding humans over a hundred trillion generations could produce a banana tree ... half the DNA is already in place ...
100,000 times the current age of the universe is a long time my friend ... nature produced a banana tree from bacteria in less than 2 billion years ... humans aren't that smart ...
So, we can now breed a cat with a horse?Yes it does.
Great books I'm sure but abiogenesis is not evolution so I'm not sure what your point is. Did abiogenesis create every species on Earth directly?A very good book about abiogenesis is in print and I read every bit of it.
The professor teaches at UCLA as I recall him.
Cradle of Life is the book

Professor J. William Schopf is the author of several books focused on the origins of life, paleobiology, and evolution. His most well-known works include "Cradle of Life: The Discovery of Earth's Earliest Fossils", "Life's Origin: The Beginnings of Biological Evolution", and "Earth's Earliest Biosphere: Its Origin and Evolution". He has also co-authored and edited numerous other volumes on these topics.
He has been consulted by NASA to examine meteors found on earth that various scientists wanted him to examine as a source of life. The time I recall he did examine them and told Scientists there was no evidence to prove life was in it.
Why his book. He exposes the reader to very vital science and the book has photos and other scientific material to back up his book. You will learn that the first life came from the ocean off the coast of Australia. It was Cyanobacteria.
I have this book also by Professor Schopf, coming to me.
Life's Origin.
Always a controversial and compelling topic, the origin of life on Earth was considered taboo as an area of inquiry for science as recently as the 1950s. Since then, however, scientists working in this area have made remarkable progress, and an overall picture of how life emerged is coming more clearly into focus. We now know, for example, that the story of life's origin begins not on Earth, but in the interiors of distant stars. This book brings a summary of current research and ideas on life's origin to a wide audience. The contributors, all of whom received the Oparin/Urey Gold Medal of the International Society for the Study of the Origin of Life, are luminaries in the fields of chemistry, paleobiology, and astrobiology, and in these chapters they discuss their life's work: understanding the what, when, and how of the early evolution of life on Earth. Presented in nontechnical language and including a useful glossary of scientific terms, Life's Origin gives a state-of-the-art encapsulation of the fascinating work now being done by scientists as they begin to characterize life as a natural outcome of the evolution of cosmic matter.
Good point. I guess you could find a 'scientist' who doesn't believe in gravity.It depends on the scientist being asked.
Geologically speaking, photos have not been around a long time. If you ring my doorbell should it matter to me if you walked or drove, took Maple Ave. or Oak St., etc.? I can't prove you didn't teleport to my door but that seems unlikely.A good way to prove what you say is a series of pictures is worth a thousand words.
Show us step by step photos for examples. Photos have been around a long time.
Yet here we are. Evolution is the only theory with ANY evidence to support it. All other theories are speculations without evidence.You've made my case, all speculation, no definitive roadmap of evolutionary change.
The evidence of creation is the finished product.Yet here we are. Evolution is the only theory with ANY evidence to support it. All other theories are speculations without evidence.

Creationism is a supernatural/miraculous event that requires no evidence, logic, or mechanism. Evolution has all three but no one can prove your theory is wrong.The evidence of creation is the finished product.![]()

Nothing is finished.
Everything is constantly evolving.
We're an experiment in progress.
Logic dictates supernatural creation. Seeing that evolution is impossible special creation is the only logical choice.Creationism is a supernatural/miraculous event that requires no evidence, logic, or mechanism. Evolution has all three but no one can prove your theory is wrong.
Of course there is no evidence, logic, or mechanism for saying aliens brought all species, existing and extinct, to Earth in their spaceship arc so I guess that is just as valid as creationism. Why do you believe one and not the other? Because one fits your theology and one does not?
