Generating Innovation: Gene Duplication and Recruitment by Joel Duff

Creationists love to claim that nobody knows the origin of new information/innovations in organisms. Well, here’s a good example.

It’s a long video, but very interesting;

Generating Innovation: Gene Duplication and Recruitment, an example from Amylase (Starch) Enzyme

Here we take a look at one mechanism by which genomes can generate innovations. That would be through gene duplication and reassignment or recruitment. The example we will focus on will be the amylase gene in mammals.

Some really obvious examples to bring up are durum wheat and bread wheat, being tetraploid and hexaploid hybrids, respectively. Sphaeriids, ferns, Campeloma, and numerous other polyploid groups are also well-known.
