Could be a good popcorn thread. ;-)
“Evolution theories are still evolving”
Of course they are. What’s the news in this?
Psychic Sea Creatures From Outer Space. Orion? Nah, I'm thinking the Pleiades.
What scientists tell you today is absolute fact.
What they told you yesterday, just forget it.
I don’t have religious problems with evolution. But I do have scientific problems. It just doesn’t make scientific sense. The statistical odds against it are astronomical.
So, we even get scientists coming up with an “infinite number of universes” theory, just to get over THAT little problem.
Just to ask one simple question, how on earth does a creature evolve and develop wings? Wings are an advantage, certainly, but how about all the intermediate stages? What’s the advantage in half-sized wings? Quarter sized wings? They are an extra burden until the point where they actually work, so how on earth could natural selection favor them?
The same with every other aspect of the physical body of any animal. And that doesn’t even get into the deal breaker—the complexity of numerous constituent organic compounds at the cellular level, more than a dozen of which already have to exist (without any purpose) so they can come together and produce even a one-celled creature?
None of it makes sense.
Science is constantly evolving. Is this supposed to be news?
Did you know that dinosaurs were an evil plot cooked up by Joseph Smith and implemented by Brigham Young to promote the transcontinental railroad so that illegal Chinese Aliens would steal jobs through granite mountains of the Sierra Nevadas so that Evangelicals would have to go on welfare .. before there was welfare?
There is a very good example of evolution, of sorts, happening right now in the US. It is fairly simple in character.
There is a species of bird found throughout the US, in three breeds. The western US breed can reproduce with the central US breed, and the eastern US breed can also reproduce with the central US breed. But the western and eastern breeds are too far apart, genetically, to breed.
And the central US breed is dying out. When it is extinct, the western and eastern branches will be two different species. Nothing distinct enough to show up in the fossil record, it can only be determined by looking at their DNA.
Dramatic mutation in a species usually fails, with any mutants either being killed by the adults around them as infants, or just by not having enough advantage to matter.
A more common evolutionary skill is for a species to either develop more chromosomes, so it has more flexibility when dealing with environmental changes; or shedding unneeded chromosomes, to save energy.
Even “simple” species can have many chromosomes or few chromosomes, depending on its needs. There is a breed of fern, for example, with about 1,200 chromosomes. Guinea pigs have 64. But people only have 46.
Importantly, as a species, we are shedding chromosomes. The male “Y” chromosome used to be an “X”, but lost one of its arms. When it completely fails, another “X” chromosome will take its place.
They think they know which one, because of the common genetic problem called “fragile X syndrome”. Another X will lose one of its arms, becoming the new Y, and then the current Y will be completely discarded.
Excuse me while I go get a banana.
