If this had been observed evolution would not be called a theory.
Do you know what a theory is?
Gravity, Plate tectonics, the Periodic Law, Oxidation-reduction and Heliocentrism are all theories. A theory is the best explanation for the data available and can change when newer better data is found. All of the above theories have been modified since their inception. The same with evolution.

Since Evolution is only ~90% correct it should be thrown out and replaced by Creation which has even a lower % of correctness. W T Young, 2008
