it is not just idea or speculation only, and haven’t been for 150 years, as it have been substantiated with verifiable evidence, that the theory of Evolution is factual information about biodiversity through genetic variations to speciation.
There are 5 alternative mechanisms to Evolution, and each mechanism have been tested, via observations of evidence, not just with fossils, but more importantly DNA testing, to show common ancestry between species and species, between subspecies and subspecies.
And more important, it has been recognised as science, by other disciplines and fields of Natural Sciences.
The only lying I see are from creationists, particularly YEC creationists and Intelligent Design proponents, who are also creationists pretending not to be creationists, particularly misinformation & propaganda published by organisations like AnswersInGenesis, Creation Ministries International, and the Discovery Institute. It is these organisations and groups of people who spread pseudoscience fantasies.
Tell me, YoursTrue.
is it only Natural Selection you have problem with?
Or do you also have problems with Genetic Drift, Mutations, Gene Flow or Genetic Hitchhiking?
