When startrek was new and it came on tv late Saturday night after rassling, I was a kid. I thought those flip up communicators were pretty cool. Lots of people didn't have a phone in their home. Never thought I would live to see real communicators.
My grandad was born in 1903, the year the Wright bros flew the first motor propelled flying machine. We watched the first moon landing at his house on his TV. He kept saying it wasn't real. It was a lot to happen in one mans lifetime. In my lifetime we have gone from a computer taking up an entire building at Cape Canaveral to a cell phone with more computing ability than that whole building had. I know how he felt.
So to say that a species wont change over thousands of generations is just silly. 200 years ago for example people were much shorter. A 6 foot tall man was not common.
There is also some evidence that average IQ has increased and is still increasing.
Those who would give up essential liberty, to purchase a little temporary safety, deserve neither liberty nor safety. Benjamin Franklin (1706-1790)

I wish I still had thumbs on my feet. When did you get them cut off? Last wednesday.
Forget that fear of gravity-get a little savagery in your life.

If you look up at the stars at night, millions or billions of stars and an even greater number of planets. I think it would be naive or self serving to think we are alone out here. However we have arrived at this point in time, I certainly think it has to be possible the same thing has happened on other planets. I too think this but I would add that I also find it arrogant to think it has all been made for us. There are 100's of billions of galaxies in what is just the observable universe. Each containing hundreds of billions of stars and planets. It's mind numbing and I think it's easier to take the "I know everything" route than admit there is just too much out there to know.

Take fish as an example, fresh water fish, salt water fish, warm water fish, cold water fish. All of them have adapted/evolved to survive in the environment available to them, or an environment that enables them to thrive. Interesting that you bring up fish. Where I lived in the Ecuadorean Amazon for two years we had various freshwater specimens of salt water species that had adapted to fresh water. Including stingrays and porpoises. The Amazon millions of years ago was covered by the Pacific ocean. Gradually the continental shift pushed up the Andes, shutting the region off and caused the rivers to reverse direction and flow to the Atlantic. Freshwater adaption was something some species were able to pull off through the forces of evolution.
