You guys do know that 90% of purebred dogs out there were actually at one point hybrids. Ill give you one example here just for conversation sake.
Herr Karl Friedrich Louis Dobermann was born on February 2, 1823 in Thuringia, Germany. Herr Dobermann worked as a dog catcher and tax collector by day and a police officer at night. He wanted a companion dog for security and protection that was large, agile, intelligent, loyal, and fearless. He wanted what in his mind did not exist in Germany at that time.
In 1880, Herr Dobermann began his breeding program with Thuringian Shepherds, early Rottweilers and German Shepherds. He visited many dog shows and breeding kennels to find the particular characteristics he wanted for his foundation stock. German Pinschers, Black and Tan Terriers, Weimaraners, Greyhounds, and the German Shorthair Pointers all contributed to his early breed stock.
Years of trial and error passed before the refined breed capable of reproducing itself now known as the Dobermann Pinscher was produced. Because of his lifelong love of dogs and his dedication to this breed, upon his death on June 9th, 1884, Herr Dobermann’s friends and colleagues perpetuated his name as a tribute to him in the breed he developed, THE DOBERMANN PINSCHER.
You really think that there were ever doxons or poodles in the wild??? LOL They were hybidized just like almost other dog available to the public, its just been happening for so long that we recognise these hybrids as pure breeds now. Hybrid fish are no different. Probably the same kind of stories can be said for alot of the fish around today that you arent even aware of. Ive got no more problem with a hybrid fish than I do a doberman pincher or a great dane which was also originally a hybridization between the irish wolfhounds and mastiff breeds.
