1. Im thinking fox or coyote, but a hyena im pretty sure is a member of the cat family. EDIT : Actually alot of people do think that, but they are a Feliformia, which is a cat like carnivore.
2. Hyenas aren't part of the canine family. They are Feliformia -"cat like carnivores. Dogs descended from Gray wolves. If your science teacher classified Wolves as a breed of dog let alone hyenas you need a new teacher. Wolves and Hyenas are entirely different species.
3. Prior to the use of DNA researchers were divided into two schools of thought: 1. most supposed that these early dogs were descendants of tamed wolves, which interbred and evolved into a domesticated species. 2. other scientists, while believing wolves were the chief contributor, suspected that jackals or coyotes contributed to the dog's ancestry. Carles Vila who has conducted the most extensive study to date, has shown that DNA evidence has ruled out any ancestor canine species except the wolf. Vila's team analyzed 162 different examples of wolf DNA from 27 populations in Europe, Asia, and North America. These results were compared with DNA from 140 individual dogs from 67 breeds gathered from around the world. Using blood or hair samples, DNA was extracted and genetic distance for mitochondrial DNA was estimated between individuals.
