It’s pretty easy for (some) people to look at the “science” of Global Warming and realize it’s much more politics than it is science.
But the same is true for Darwinism. People treat evolution like something proven and beyond question. It isn’t. The core concept of species changing into different species is totally unproven and very much open to question. It’s time to realize that Darwinism is much more politics than it is science.
Really...fixity of species is a nebulous term....no one actually knows at this time if the variation seen in organism is pre existent (like a jumping gene or transposon)or a novel SNP. What is true is that mutations that go to a point where the organism dies or cannot reproduce are lost to genetic pool variation.
Either way, darwinism or neodarwinism is not a very complete explanation. As such it should be relegated to a theory which tried to encompass the known science of the day.
The language of DNA,RNA, epigenetic controls, restriction enzymes, correction enzymes, intracellular transport architecture, protein synthesis, intercellular communication schemes, etc....make the concept that an organism can cross the large barriers of plant or animal differences highly unlikely. I am overlooking the elephantine problems associated with formation of a cell which has those capabilities. (the “but we are here” argument is circular reasoning)
