Great read. In the interest of opening the debate on lack of novel modern domestic animals, the best example I can think of would be the Russian domestic fox experiment, conducted by zoologist Dmitry Belyayev beginning in 1959. The domestic variety was created for the purposes of understanding the domestication process. By the 4th generation, pups had begun to exhibit dog like responses to handlers. Subsequent generations exhibited more and more domesticated traits. Eventually, the foxes were expressing most of the domesticated traits. The adult foxes began to exhibit widened skulls, shortened snouts, floppy ears, curly tails, which are all juvenile traits certain domesticated species retain in adulthood. Many other behavioral changes occurred, that are hallmarks of domestication.
There are many other species that have been "domesticated" in the last 150 years or so, particularly the model organisms that are bred on a large scale for scientific studies.
Eukaryotes aside, many other organisms that have far shorter generation times have been "domesticated" in systems such as fermented foods.
I put quotation marks around domestication in two cases as domestication may be interpreted differently.
