Evolution is about descent is it not? Reproduction is central to descent is it not? Yes and yes.
Bones cannot answer the question as the shark example shows.
Now you've gone wonky again.
And you might want to go reread the part where I explained to you how "bones" *can* shed light on questions like this.
They are all fish in every way yet their reproductive systems are completely different.
If you think they're "completely" different, you really haven't been paying attention.
So bones cannot answer the big questions of evolution.
Beware of vast overgeneralizations, they're never, ever, ever wrong in a trillion years...
Actually, "bones" can answer *many* of the "big questions in evolution". And they can shed light on this one. They just can't provide the entire answer on this particular issue all by themselves, you have to gather information from various sources.
I don't know why you think that's somehow vastly profound.
What continues to bother me is that we know now that a single celled organism found in pond scum has far more sophisticated mechanisms than NASA's space shuttle facility.
There are engineering marvels within the cell that far exceed man's ability to engineer. Complexity that our finest scientist continue to be baffled by. Here is an exerpt from an article regarding the human genome project.
"But to my mind, the most memorable moment in these last few weeks of genetic astonishments came during an interview with computer scientist Gene Myers at the Maryland headquarters of Celera Genomics, just a few days before the genome maps were made public.
'We're deliciously complex at the molecular level,' Myers said, gesturing with his fork. 'We don't understand ourselves yet, which is cool. There's still a metaphysical, magical element.'
Myers was the guy who put together Celera's genome map. Celera's sequencing machines had broken the 3 billion chemical letters in a strand of DNA into millions of fragments, each a few hundred letters each. 'What really astounds me is the architecture of life,' he said. 'The system is extremely complex. It's like it was designed.'
My ears perked up.
Designed? Doesn't that imply a designer, an intelligence, something more than the fortuitous bumping together of chemicals in the primordial slime?
Myers thought before he replied. 'There's a huge intelligence there. I don't see that as being unscientific. Others may, but not me.'"
