Evolution is occurring...
Only in reverse!
You're only betraying that you don't have the first clue about what evolution actually is. It sounds like you think there's a direction to evolution - like it has an end goal in sight somehow. From that perspective, I suppose, evolution could move "forwards" (towards the goal) or "backwards" (away from it). But that's a complete mistake. There's no end goal for evolution. Hence there is no "forward" and "reverse".
Beneficial mutations can occur but they are extremely rare.
The majority of mutations are harmful.
Harmful mutations are not selected out or rejected, because they are often too minor to be fatal, and to minor to affect the reproduction of the species.
You mean not
all harmful mutations are selected out. But some certainly are.
Suppose, for instance, that a human foetus's DNA happens to have a mutation that prevents a vital organ from developing - the heart, say, or the brain, or the lungs. That foetus certainly will not go on to reproduce and pass on that particular harmful mutation. In fact,
all such foetal mutations are selected out.
Millions of people are walking around the Earth right now with harmful genetic mutations, but they can reproduce just fine!
Clearly there are degrees of harmfulness in genetic mutations. Who'da thunk it?
Over time, more harmful mutations are passed on than beneficial ones, which cumulatively cause the eventual extinction of the species.
Wow! You got that precisely ass-backwards.
Over time, individuals who carry too many harmful mutations are inevitably outbred by other individuals that lack those mutations (and who carry beneficial ones). That's natural selection in a nutshell.
What goes extinct is not the species, but the harmful mutations.
Understand?
If this is true, then the number of species on the Earth should be reducing over time.
Which is exactly what we actually do see.
The truth is that human activity is currently reducing the biodiversity of the planet. It really has nothing to do with mutations etc.
Genetic Dilution is also going on, and it is not ultimately beneficial. It can have temporarily benefits, but Genetic Dilution causes the permanent loss of genetic code over time. And when it is lost, it is lost forever!
You really need to read something other than creationist pamphlets that are dropped in your letter box.
Get this: there's no ideal "perfect" genome. There never was. Over geological time, the overall volume of "genetic code" has increased, not decreased. At the start, there were simple codes and simple organisms.
Mutations don't just "delete" genes. They also add them. Call it "genetic augmentation" if you like.
With both of these occurring, God’s original design information, the original genetic code, is cumulatively corrupted and lost over time, not gained.
Why doesn't your God do anything to prevent corruption of his perfect design? Oh wait, no it's not perfect, you said. Just "good enough". A temporary fix. Right?
If evolution ultimately causes increased survival, stronger creatures, and more heathy variations, then the number of species should be exponentially growing in number and in frequency, but it is not.
Bad reasoning, once again.
Suppose that evolution somehow produced the "perfect" bacterium, which was effectively immortal and able to survive in any environment. That bacterium species would out-compete every other form of life on the planet, until it was the only life left. Species would gradually be out-competed by the "super bacteria" and disappear.
The thing is, measures of success like "stronger", "more healthy" and so are always determined by the environment. Research the term "ecosystem".
