Evolution isn't always sucessful! Selective adaptation (evolution) is always a gamble... if a species adapts to a particular habitat - be that food, dwelling, location, etc. - and the habitat changes more rapidly than the animal can adapt then extinction is likely.
Extinction can come about through the intervention of other species, as well. A ground-dwelling bird could be wiped out by the invasion of a new predator, etc. I'm sure you can think of many examples. This is why invasive species are such a concern.
And make no mistake; humans are continuing to evolve. We are considerably taller than we were 2 millenia ago, and our smallest toe (pinky toe) is getting smaller and smaller. We may not be getting any smarter as a species but we *ARE* changing.

Yes evolution does not speak to the actual origin of life, I do appreciate that you made a real attempt to challenge evolution. However, from you question I can tell that you don't have any real understanding of evolution, nor is your argument grounded on any kind of rigorous logic. Fossils residing underground in no way suggests an aquatic extinction event, you give no precedent for this nor is your logic clear in even how this suggests an aquatic event. What you are making is simply a statement, not an argument. Also, evolution occurs on geological timescales. Were talking tens and hundreds of thousands of decades, or millions of years. We will never be able to see ourselves evolve, period. Unless the human race survives another hundred thousand years or so. How are rapists and killers selected against in the environment? I cannot think of a negative biological impact for these traits in terms of survival or reproduction, which are the major driving forces of natural selection. Also, traits that are negatively selected take thousdands of generations to be removed by natural selection. How are we getting dumber? Where is the empirical data supporting this (your source)?

we've info of dinosaurs, so as that they are real. Evolution (the theory that each and everything developed into some thing thoroughly diverse from the unique) is an man made concept. Evolution or diversifications interior of a "sort" is achieveable and does ensue. Dinosaurs died previously the 1st human replaced into created, for that reason they weren't alive while Noah walked the earth, not to show while he equipped the ark. Dinosaurs have been created on the 5th day and died on that distinctive day, which lasted a minimum of 7,000 years. (Genesis a million:20-23) All cutting-part animals and guy have been created on the 6th day, which additionally lasted a minimum of 7,000 years. (Genesis a million:24-26, 31) those time figurations do not journey with what scientists theorize because of the fact they use relationship strategies that are actually not very precise the older the object is that's being dated. Carbon-relationship is likewise immensely laid low with how water impacts radioactive decay of count. Scientist fail to contemplate the water harm from the flood (aka the ice age(s) of Noah's day. while there's a dicrepency between the bible and technology it particularly is often greater sensible to bypass with the only that has been there from the commencing up of the earth's historic previous.

We are not neccesarily getting "dumber", and that certainly can't be a basis for contravening the Law of Evolution. Being a "rapist" or a "killer" is not a trait that is inherited genetically and does not pass on as a gene from parent to child. This is a psychological problem that many humans encounter from external stimuli. When something happens in our childhood or life, it pushes us into a negative lifestyle and develop behaviors that are abnormal. And, who's to say animals don't develop these behaviors in their life? There are hundreds of feral dogs and cats in the US alone.
Also, 1 million years is NOT a long time compared to the evolutionary history of other animals. You can't expect us to grow super brains and become masters of our environment in that short of a period. What else do you propose we build our houses out of if not rocks and wood? Those are, clearly, the most available forms of structure. Not everyone can run around building their houses out of reinforced steel or whatever. Moreover, it took billions of years just to go from protists to multicellular organisms to human life forms. I don't see where you believe we are stagnated, because we are certainly not. There is so much potential in the human race, and the only reason that it may seem we are "stagnated" is because the media portrays the negative psychological aspects of humanity. We are moving forward at light speed, whether you may realize it or not.

Probably the best answer to your question does not deal directly with evolution as it pertains to humans. The problems you list, mainly crime, are largely socio-economic and environmental, not questions of evolution.
Mans existance has shifted from, "What can I hunt and gather to eat today?", to "Who do I call for delivery and what do I wach on the tube?".
We have "Evolved" technologicaly to the point where man has stopped "learning" to survive. Ok, maybe not totally a bad thing, but society has not the skills to teach our children how to deal with this, herein is the problem. What has stagnated is our education in general. Hence disparity, hate, crime, etc.
In nature, all animals are a product of their environment, so they evolve accordingly. So says the law of nature. If you want to survive, you must learn.
Enough of my soapbox...
We still make our homes out of rocks and wood because that is the material we have to work with. (About 20% of all new homes are being built with steel recently, almost 40% in Florida where I live. Termites.) Plastics and compisites are out because they dont go away. Rock is reuseable, Trees are renewable. At least they are supposed to be...
Fossils. You see "evidence" of an "aquatic level extinction" (whatever that is), on top of the dinosoaur fossils, well probably because at the very end of their time on this planet, the earths temp averaged almost 108 degrees. the ice caps were nearly melted, ocean levels rose to never seen levels, and continental water was almost completely depleted. The planet was nearly a desert. Almost all life existed in the oceans.
There have been may scientitst out to prove the "magic bullet" meteor theory, but the fact remains that, within earths history, almost all, about 80%, species on this planet were exterminated in less that 1000 years following an impact.
The fact that it took humans 40,000 years to move from stone tools to metal, and only 4-5,000 to get where we are now, should speak for itself. At least in geologic terms.

Evolution is a real force in the biological world. Humans have gotten by for a while by reshaping nature with our tools rather than being shaped by it, so natural selection, at least for humans, has been short-circuited. What you're talking about, however, is cultural, not biological. I worked as a microbiologist for a while, and have seen bacteria evolve into "superbugs" that are resistant to many different antibiotics. Other pests in our lives have also adapted to our application of chemicals to control them. They're evolving, but we aren't (yet). Wait till our cushy technological society collapses. THEN you'll seen some evolution!

im not a big fan of evolution, but it could be possisble. we are moving forward though, not with survival, we have already hit the top of the food chain, why move any higher? we are moving forward with science. what other creature on earth knows how to cure cancers? To put another on a moon? Humans are the only ones that have touched the moon, not dogs, sharks, or anything, humans have done that and are still doing that. Sure there are some physcos, but that is because the choose that. We are still moving forward, just at a slower pace.

While, there is still a lot of negative things that go on in this world, I believe there are actually less than there were in the past. The difference? Now that we have television etc, ANY time something bad happens, we all know about it so it seems like there is a lot more than there used to be.
Perhaps the next step of evolution is not something to be measured by the physical body, but by the nature of the soul itself.

I agree with your thinking. But don't be surprised someone will say we are getting dumber is a proof of evolution.
I finished high school a year ago. When they taught us evolution, I just attended a class and that was all. It really made me sick to hear that I am from protists and then apes.
If that was the case we may have been seeing signs of becoming different creatures and so the other organisms.
Don't believe in this freak.
