Different dogs look incredibly different - but that doesn't mean they are necessarily more diverse.
To learn more about this topic, start your googling with these keywords:
phenotypic diversity - the range of different observable traits in a certain organism - for example, size, color, strength, and friendliness.
genetic diversity - the variation in the genetic information within and among individuals of a population or species
artificial selection (or selective breeding) - a process used by humans to develop new organisms with desirable characteristics

  • I think breeding a large Maine-coon/lynx/cheeta/serval mix and then refining ou the different traits would be awesome (long legs of the cheeta, serval and lynx, no retractable claws, like cheeta, amicable and emotionally less temperamental, like a coon and a serval, more loyal and family oriented like a cheeta and a serval and a coon, large paws to make up for the lack of claws, like the lynx, then benefit from the health of the wild types), like successful wolfdog breeds, like the German Shepard, savanah cats have proven very successful (part domestic, part serval). And using 4 types of stock like this could render a varieties of coat colors, patterns, types, sizes, etc. If love a rich grey/spotted, medium/fluffy, lanky, social healthy cat that's 35 lbs, wants to snuggle and doesn't ruin my furniture.

  • Short answer, we’ve never really bred cats past their base forms. So we really only see regional genetic differences dictated by availability of mates vs a specific breed genetic difference based on desired outcomes of mating by us an outside influence. AND this is probabaly due to the fact cats aren’t really domesticated as much as acclimatized to living in shared environments with humans. And why is that you ask? Cats have really had one primary job. Vermin extermination. Which they’re naturally pretty good at..... Dogs have had many more jobs that required very different behaviors and even physical characteristics that had to be planned for or protected during the breeding process to maintain instinctual behaviors or remove them.

  • Breeding program not likely. Remember that when you bred to a standard the ones that don't meet that standard go in the trash. Notice how most breeds were developed in Germany , well at that time they also tested new medicines on death row prisoners not lab animals . It was a different time with different ethics.

    Kolila GephartKolila Gephart3 dagar sedan
    • @Warwick Lewis Selective breeding can be problematic even if done using “humane” methods. Case in point: brachycephalic breeds like pugs. Looking as dumb as they do sometimes comes at the cost of THEIR EYES LITERALLY POPPING OUT IF THEIR SKULLS, but that’s a price some breeders are willing to pay

    • @Gi Gi ironically while dog breeders have started breeding for a longer snout in some brachycelphalic breeds cat breeders have now produced brachycelphalic cat breeds that suffer the same problems. The popularity of snub nosed flat faced freaks is a huge selling point. In the long run as long as there is demand there will be breeders who are willing to breed undesirable traits. German sherperds are a modern breed. Created in the 20th century by mixing various other breeds to creat a German super race of dog.

      Warwick LewisWarwick LewisDag sedan
    • @Warwick Lewis The issues are not eradicated when people think they are actually good. I.E. compare examples of brachycephalic breeds today to examples of the breed from 100 years ago. Their muzzles have become shorter, not longer. To the point that breeds like the pug can actually have their eyes POP OUT OF THEIR SKULLS because the eye sockets are too misshapen. Bulldogs rely on IVF & cesarean procedures to reproduce more than ever. Other types of dog like the German Shepard have been reliable working dogs throughout history, but now show breeders select dogs to have sloping backs- ruining their athletic abilities, leading to hip & elbow dysplasia, among other problems. Selective breeding can improve a breed, or it can ruin them- which direction things move towards depends on intent as well as method. There’s not enough incentive to breed healthy animals, while breeding freaks is profitable

      Gi GiGi Gi2 dagar sedan
    • @Warwick Lewis What's not true? I know that efforts are being made to assist in safe breeding, but the problem of inbred health issues still exists and won't go away so long as humans keep the demand going for superficial traits in dogs. It's selfish. Human inbreeding is a much scarcer problem considering we're more diverse genetically, and it's also more complex because it's consensual. I don't care to get into specifics about humans for that reason. It's not comparable at all. Dogs are only allowed their relatives with whom to carry out their instincts. Breeders don't allow them freedom to choose. You're acting like breeder dogs get to choose. If dogs are left to their own devices, they'd mix and would solve the problem much more quickly.

      coffeefrogcoffeefrog2 dagar sedan
    • @coffeefrog that's just not true. There are specific issues regarding certain breeds but efforts are made to eradicte these problems by only selecting healthy dogs for breeding. There are specific issues related to human beings should we stop people who have a higher chance of certain genetic disorders from breeding ?? It is an unfortunate fact of life that not every baby is perfect. This applies to puppies as well as humans.

      Warwick LewisWarwick Lewis2 dagar sedan
    • @Warwick Lewis It's an example, which is not exclusive to one breed, and there are others with different issues. And people fuel the breeding industry regardless due to completely superficial reasons. It's selfish.

    • @Gi Gi wait, you're talking about traditional siamese or modern siamese?

      Shinx The LionessShinx The LionessDag sedan
    • @Shinx The Lioness Siamese are known for being talkative & attentive to their owners, but also for being active & athletic. The norm is that they are inclined to hunt, actually. You’re right that not all individuals adhere to those norms, but the breed is actually considered one of the top choices for mousers!

      Gi GiGi Gi2 dagar sedan
    • @Gi Gi fair enough, but even felines being more lonely than wolves, they both hunt very well so I still think we can someday make their hunting instincts way weaker. Also, I'm not saying Siamese don't hunt, they just do it way less than a regular cat, they are way tamer than a shorthair in general, of course, there will be exceptions but overall the more gentle and tame behavior is listed as one of the characteristics of the breed. Btw my cat is perfectly healthy, he's just very shy and calm in general.

      Shinx The LionessShinx The Lioness2 dagar sedan
    • @Shinx The Lioness Cats are not pack animals by nature as dogs are. They are inherently more independent than dogs. Selective breeding has only accomplished so much, even with canines. Also I’ve had Siamese cats before & they knew all too well how to hunt! My current cat is an indoor moggie for a number of reasons, but a Siamese I had as a child would frequently bring home full grown rabbits. He was the bane of neighbourhood dogs & even took on deer just for the hell of it. Didn’t stand a chance of catching one, but he liked to make sure they knew who was king. If you have a Siamese who can’t hunt, it’s either because it never learned, had the opportunity or is unhealthy (probably the former, but some Siamese are more disposed towards problems with their eyesight)
