I've read that argument put forth by Brittanica before,, and it doesn't hold water- first, measuring genetic differences does not account for new information- it merely proves micro-evolution- adapting of species based on gene info already present between like kinds- new info is not being introduced as would be necessary as I've stated before for a 'morph' to an entirely new KIND- we've known for quite some time that gene info can change drastically during micro-evolution- but it always plays out using all the info already present in a species or KIND.
The whole Brittanica article falls apart on one key issue "New Info" - they showed 'Changed Info' but not "New"
