It's fairly obvious to most people that complex capabilities like flight or the sonar which whales use could not evolve, hence the popular amusement at the little dog-and-pony shows which evolutionists produce to try to explain such things.
What if an outsider were to come up with something hundreds of times more fabulous than flight or sonar. For onstance, what if a creature were to be found which, without recourse to any technology, was naturally able to withstand the cold and vacuum of space and somehow navigate and travel across cosmic distances?
Is there any point at which even the most hardcore evolutionist would have to stop, examine the evidence, and say to himself "JEEEsshh, now I KNOW that shit can't evolve... time to go back to the drawing board."
If there is no such point, than evolution is basically unfalsifiable and clearly a pseudoscience.
I believe that a number of things which are normally termed "paranormal" represent just such a case. Evolutionists generally pooh-pooh such evidence and attempt to discredit the people involved with such studies, since they instinctively dislike the idea of having to deal with anything like that within an evolutinoary context.
Nonetheless, there are other people and groups of people who do not have the luxury of trying to ignore things which do not fit within their ideological paradigms. The king of France in the 1400's, for instance, did not have such a luxury. The Catholic church, apparently making up in thoroughness for anything they might lack in celibacy, took several hundred years to analyze the case of Joan of Arc, and ultimately determined that at least some of her activities required information that she had no way of having other than for paranormal means; they cannonized Joan in the 20'th century.
Likewise the US military does not have the luxury of ignoring such things. You can check out this article on the US military's interest in remote viewing or do your own google search on 'Stubblebine' and 'remote viewing' at your leisure. Books have been published on soviet activities in this area and I presume American general officers are not paid to investigate pseudoscience.
My own take on this sort of thing as I've noted resides on bearfabrique.
I believe I've done a more adequate job of presenting these ideas on this page than I had with previous efforts.
Rupert Sheldrake's www site is Sheldrake.org
Sheldrake is a former director of studies in cellular biology at Cambridge University who has made a second career of using statistical methodology and intelligent experiment design to investigate things normally termed "paranormal" and is generally viewed as public enemy #1 by the CSICOP crowd and other such "science vigilantes". If nothing else, his methods are unassailable and his credentials are significantly better than theirs are. The best starting point for reading Sheldrake's view of nature is "Seven Experiments Which Could Change the World", which is available as an inexpensive paperback. Sheldrake notes that the big questions in science no longer require "big science" or large sums of money to investigate them. In particular, major compute power which not long ago was exclusively found at government agencies and universities, is now available to the public for under $1000.
