what I find logical is that with so many millions of species in the world there should be some mutations and evolution going on somewhere and this doesn't seem to be the case.
I mean something on more advanced kinds of animals not metabolic changes in bacteria which are the most primitive forms of life. So why has the process of speciation through mutation and natural selection ceased? Why are there no new species appearing even out of evolutionary changes that began let's say 10 million years ago and could be getting completed today, if that's the time scale we need.
Evolution doesn't have an end goal for completion. The species you see around you today are the results of evolution, but they are not the pinnacle or completion of evolution. Changes in their environment affect them every day, and if a beneficial mutation comes along (beneficial in that current environment), the population may change. But it most likely won't be an abrupt, large change from one generation to the next.
Human beings are not the "final product" of evolution, just because we're this intelligent. Even though it's true to some extent that nature becomes more and more complex, evolution doesn't have a goal of perfection. Again, that would be... God. But I would say that the longer an environment is stable, the more 'perfect' (for that environment) the life forms living there will be over time.
I'm a little sad that you didn't watch the video I linked to, although I don't blame you because it's so long and may seem boring. All of those HHMI videos are great for education about this, though (there are links to the others around the video I linked to).
Whales and dolphins have vestigial hind legs and pelvic bones that are of no use to them today. Some cave-dwelling and subterranean animals have non-functional, vestigial eyes, sometimes beneath the skin. Manatees have toe nails on their flippers, toe nails that are similar to an elephant's, and seem to share a common ancestry when we compare DNA. These are all living creatures today, not fossils. In the fossils though, we can find the links between the various forms (as you would have seen if you had watched the video).
Bacteria are often cited because they change so fast. They multiply at a ferocious speed.
You have to be willing to educate yourself on this subject to gain knowledge - evolution can't be summed up in a few cliff notes here. Creation can: "God wanted there to be life, so he created life". On the contrary, you'll have to want to educate yourself about this. A few years ago, I thought I was doing research, but what I was really doing, was reading what science said, and when that clashed with what I believed, I would search for answers from "anti-science" (pro-Bible creation) websites, they would give me a contrary answer, and I could 'relax': "Those darn scientists were lying all along after all. *phew* ". Turns out though, that those "anti-science" people will go to any length to 'prove' the Bible right - even if it involves lying or presenting 'proof' that has been refuted years ago. Of course there are also scientists who lie and create fraudulent work to gain fame and money, but since science is a process of testing again and again, they will in most cases be caught at one time or another.
[edit] Hmm... this post turned out to be almost a copy of dissident's post - that was not my intention. Great minds think alike, I guess. Well - not that I have a great mind... [/edit]
