Are dogs evidence of evolution?

Question

Most modern dog breeds came into existence in the 1800s, because people were bored after the industrial revolution. God didn't create these different breeds; man did. Dogs are obvious proof that through selective breeding a life form different than its ancestors can be created. These modern dog breeds evolved thanks to human interference.

Since dogs prove that the evolution of one species is possible, does it follow logically that all species evolved differently due to different environments?

A lot of people are saying it's only evidence of evolution within a species. So you're telling me evolution within a species is possible, but not evolution within a genus/family/order/class/phylum?
Seems like a logical fallacy. Does it seem that way to anyone else?

Seems like the different breeds in a species, and the different species in a genus, and the different genuses in a family, and the different families in an order, and the different orders in a class are faaaaairly good proof of evolution.

Answer 1

Dogs? When I seek an example of how evolution works I just look to the banana.

Answer 2

Dogs are all the same species, so no.

But dogs (and domestic chickens) did provide a big clue to Charles Darwin regarding the origin of species. He saw that domesticated animals like dogs and chickens showed a remarkable variety of forms but that members of those species in the wild all looked the same. He reasoned that all being had an inherent ability to express many characteristics but for some reason, only one form was best suited to a particular environment. This got him to the idea of natural selection as the force that makes choices over which member of a species beeds most and how that influences the whole population over time.

In comparison, the intentional breeding of dogs or chickens to have particular characteristics that are not well suited to the wild would be "artificial selection".

Answer 3

I agree with the first post here, but, I will elaborate a little bit on it, for fun.

Most animals created between interspecial crossbreeding are actually steril, for instance a horse and donkey crossbreed creates a mule. A mule can not reproduce with a mule, (or anyone else for that matter), so, the evolution could not continue.

Species, by it's very deffinition, can not produce offspring with other species. This is scientific fact. So, in order for us to have actually come from monkeys, a monkey would have to actually mate make a human and then the human would have to mate with another human. Where did the 2 humans come from is the question.

Evolution in general abviously exists to an extent. The human species used to have smaller foreheads and stronger jaw muscles, and this has been proven... but it's the whole monkey thing that takes a huge leap of faith, as well as breaking a few key physical laws, that keeps me from believing it. I mean, science itself basically says that we couldn't have come from monkeys, even though these are the same scientists who believe in the whole monkey thing.

Answer 4

All species, including humans, have forensic evidence of their evolutionary history contained in their genome. For instance, humans still carry deactivated amphibian genes in their genome. Domestic dogs carry evidence in their genome which shows they began their reproductive isolation from wolves 40,000 years ago on the steppes of Mongolia.

But the logical way to show evolution is not through the domestic dog example.
Simply take three conditions
1. replication
2. heritable variation
3. differential fitness
And apply the necessary mathematical algorithms; evolution must occur

And as far as any macroevolution/microevolution distinction, that would be based on a genetic fantasy that nucleobase replication errors somehow stop after reproductively isolated populations reach more than 0.5% genetic difference.

Answer 5

Dogs are all one species, Canine familiaris, with different breeds, just as humans are one species with different races. All dogs can produce offspring with other dogs.

To the rest of the question: without a doubt, selection pressures in isolation lead to changes and speciation. This has been observed over the past 80 years with the wallabies living on Hawaii, escaped long ago. They developed liver enzymes to be able to eat plants that would kill their Australian ancestors. The Hawaiian wallabies cannot produce fertile offspring with Australian wallabies. Speciation observed.

Fireball, truth is subjective. Facts are facts. Please learn the difference.

Answer 6

It proves they came from a common dog ancestor...not that they evolved from a common ancestor with lions or bears or any other carbivore that is not interfertile. Speciation is not an issue with creationism as many modern animals are derived from the ones that were on Noah's Ark and is observed as you state in the wide varieties of modern dogs. Genetic variation allows for this to happen and can be guided by environmental variations or human breeding practices. Cattle breeders can show you that as well as many other breeders of livestock or flower nurseries.

Answer 7

Great so you just proved that evolution occurs under the species level, and then tell me that because dogs evolve under the species level it is possible for arthropods to become humans through evolution. Its like showing people a spider to prove that spider-man is really a possibility.

Answer 8

Domestic dogs are descended from wolves but in the main they cannot breed with wolves and are now a separate species.

Answer 9

it fairly is information against the theory of evolution. clever human beings breeding canines is the rationalization there are various of of categories of canines. yet clever human beings won't be able to breed canines into different animals. There are obstacles the place substitute won't be able to go previous. If all canines have been decrease back to the wild, practically all could die out in the previous reproducing by way of fact they are in a place to no longer hunt for survival. After some generations, they could revert back to a unmarried canines breed. organic decision is stabilizing, no longer diversifying.

Answer 10

We only helped make new breeds not a new species. A dog is still a dog.
