Tell us, where all variety we see now and in the past (fossil records) came from if there is no mutations and no changes - if brother Darvin was incorrect?

Please, enlighten us and the rest of the biologist's world about the origin of species.

And about why 1 billion years ago we had less diverse variety of them, and 2 billion years ago -even less.

Also, explain why human DNA is so close (98%) to ape's DNA and why human anatomy, blood types, skeleton features, even social behavior is so close to ape's one?

And why human fossiles resemble more and more apes and other animal remnants as we go back in history 1 million years, 2, 5, ... By other words, distance between us and the rest of mammals is decreasing as we go into the past?

Also, explain how adaptation works and how it produces variety of DNAs WITHOUT random mutations and survival of fittiest.

And why changing DNA can not change more than 0.5% to become uncompatible with original DNA and we then classify it as separate specie?

And where exactly the difference is what you clearly call new specie: 0.4%, or 0.5%,or 0.6%, etc?

And what difference you keep calling "transition" specie - 0.4% or 0.6% ?
