There are almost 20k known species of bee which is tiny when compared to the 400k species of beetle. You think these things haven't changed? If we went back 30 million years that all of these species would look the exact same?
Things change and selection pressures lead things to change at different rates...and this still takes place over thousands of generations through a population. Many animals reproduce once a year so do some quick math in your head and guess how many generations it would take at once a year and 10k generations.
>No changes, no mutations, nothing that can actually be demonstrated and observed.
Except sometimes we can see speciation
>If they can find any set of fossils or bones that look like they MIGHT be connected to another animal, they're quick to say
Try Vertebrate Life or Principles of Animal Physiology if you want an answer as to how you don't have any clue what you're talking about. I'm sure there are plenty of other textbooks to choose from, too...these are just two ones I own that would do a great job covering these for you.
>from a single cell that just popped out of nowhere.
