Again you are showing a basic misunderstanding of how science and within that evolution work.
The hard evidence you are looking for is contained in the fossil record.
As far as the spider question this might help explain that process.

It appears that most of your doubts regarding evolution are based on many commonly held misconceptions.
“When Charles Darwin first explained the matter, many people either wouldn’t or couldn’t grasp it. I myself flatly refused to believe Darwin’s theory when I first heard about it as a child. Almost everybody throughout history, up to the second half of the nineteenth century, has firmly believed in the opposite - the Conscious Designer theory. Many people still do, perhaps because the true, Darwinian explanation of our own existence is still, remarkably, not a routine part of the curriculum of a general education. It is certainly very widely misunderstood”. ~ Richard Dawkins

It is a scientific theory that states that “Electrons *must* exist to balance the charge of an atom” and that theory is accepted because to date it has not been disproved.
Your arguments against evolution have provided no information to disprove the theory
In fact each question you have asked I was able the use the google and find a scientific explanation with in a matter of minutes
The theory of evolution does not state that mammals ever existed with out internal organs or a skeletal system. Those systems came about long before mammals appeared on the scene
I’m sorry, Ira. What you see as science I see as conjecture. The question to me is not whether there are extinct spiders that looked different, but why this bizarre ability to spin webs could have possibly come to be. Or why hummingbirds can flap their wings 200X per SECOND during courtship. Was it designed? If so, at least that should be admitted to in bio books. If not, I cannot believe that a soup of chemicals could have blindly progressed so extensively and intricately. To me, macro-evolutionary theory is as absurd as global warming, or pardon me, “climate chaos” theory. Cheers, Bob
