It is very easy to say what is Not Evolution: if there is no change in any population’s gene pool… there is no evolution. The gene pool literally has to Change in order to have Evolution. And by change, it is meant:
-
the loss of a gene, the garbling of a working gene, the appearance of a brand new gene (either good or bad), OR EVEN …
-
the change in percentages in a gene pool regarding Existing genes:
a) if a present population has hair genes in these proportions: 12% fuzzy, 80% straight, 8% curly.
b) If we find a fossil of the same kind of creature (say we think it is 100,000 years old) … and microscopic analysis of the fossilized hair and hair follicles reveal an ORIGINAL proportion of: 30% fuzzy, 30% straight and 40% curly …
that is Also considered a change in the gene pool. So that is Also evolution.
**But perhaps you are asking (or also asking) what would Disprove evolution … in the broad sweep of things… if we find Any pattern (not a one-off exception of mysterious context) where a large number of large mammal fossils or human fossils are mixed in with dinosaur fossils… **
… this would be devastating! Because one of the most secure “testable hypotheses” in Evolution is that until the Dinosaurs greater than 50 pounds were wiped out … it was virtually impossible for mammals to diverge into important ecological niches… for in those niches they were quickly eaten and depleted.
After generations of research, we STILL haven’t found any systematic pattern of large mammals mixed in with dinosaurs.!
