Why Haven't Dogs Evolved?

[strollingbones]

Think woodie was upset when he found out the 'dogs playing poker' paintings were fictional.

have some respect......i grew up with that picture on the wall.....and i am sure its packed away somewhere

Because the evolution heresy is false.

by the tenants of that "theory", a dog would have grown a nose that acts as an extra limb to reach leaves on the higher branches.

not really since dogs have no trouble fining food why on earth would an elephant like trunk be needed?

Besides dogs don't eat leaves

Or a giraffe like neck.

Who says dogs haven't evolved. They started as wolves living with humans because they helped each other get food and fight off predators. Wolves have evolved so much that now humans provide them food and pick up their stool, and they get to lick their human's face right after licking their own balls.

If you told any wolf 50,000 years ago that is how things would turn out he'd say, "I can live with that".

That is one of the funniest clips I've seen. Holly hell a monkey-fish-frog.

What if they're home owners instead of tenants?

From the OP:

Can someone explain why they haven't evolved into different species?

I don't know whether it is due to lack of reading comprehension or general ignorance, but no one has addressed this question in a comprehensible manner. Different species have noncompatible DNA for the purposes of reproduction. No one disputes adaptation within species; that is why polar bears are white. The question is where did different species come from? To say that dogs evolved from wolves or even "mongoose-like forest dwellers" misses the point: If they still can (or could) interbreed with each other, then they are all the same species from an "Evolution" standpoint, since that theory purports that species can transform into other species with which they are genetically incompatible (e.g., fish into reptiles).

I am not philosophically opposed to this concept, but I have not seen a logical explanation of how this has (or even might have) occurred. Instead, this question is simply glossed over as somehow happening "over millions of years" or else discounted altogether as some sort of "creationist" trickery. (As an agnostic, I find the latter to be particularly disingenuous.)

Is there anyone who can answer this question objectively?

They have been subjected to intense genetic specialization for 5,000 years, resulting in the greatest intraspecies variation in Earth's history. Despite a 100X size disparity, a Great Dane and a Chihuahua can still (theoretically) mate. Why? Because they are both still DOGS.

Why would they?

And why do you think that no evolution has happened- simply because no new species have resulted?

Dogs are a great example of human engineered evolution.

Why did ancestors of Horses- and Donkeys- result in eventual Horses and Donkeys?

Horses and Donkeys can crossbreed- because they are genetically closely related- but their offspring are sterile cross-species- mules.

And those lines split a few million years ago

• The horse family, Equidae, has three main divisions based on anatomy and DNA studies. (Oakenfull et al 2000)
  • The caballines - include domestic horseand Equus przewalskii, a wild ancestor (Forstén 1988)
  • The asses - include domestic donkey, African wild asses, and the hemionines (Asiatic onager and kiang)
  • Zebras
• The genus Equus appears around between 4 and 2 million years ago (Pliocene) (Oakenfull et al 2000) (Steiner & Ryder 2011)
• A pony-sized horse, Hippidion, appeared in South America after the Isthmus of Panama formed about 3.2 million years ago (Orlando et al. 2009) (Weinstock et al. 2005)
  • Previous studies had suggeted these Hippidion lineages had more ancient orgins, around 10 million years ago
  • At least two South American species are recognized; one in high altitude Peru, another in Patagonia and Argentina
  • Equus dispersed from North America to Eurasia around 2.6 million years ago (Steiner & Ryder 2011)
• The earliest known true African wild ass (E. africanus ) dates to 1.5 to 1.7 million years ago in Olduvai Gorge, Kenya. (Churcher 1982)
  • Domestic donkeys are descended from African wild asses (Clutton-Brock 1999)
  • Donkeys and closely related Asiatic asses have a long separate evolutionary history. (Forstén 1988,1989)

Most people seem to want to see some Hollywood style change from one form to another in an instant. It doesn't happen like that, there are usually very small mutations and changes over millions of years. All you have to do is google 'transistional fossils' to see what archeologists have found.

And on a side note, the fossil record isn't some neat full filled out encyclopedia of fossils with every gap filled and an example of every thing that ever lived. We only have maybe 35 PARTIAL T-Rex skeleton fossils of probably tens of millions of examples that actually lived. Scientists use all knowledge bases and correlate information into an overall picture that is pretty damn accurate. The same was done when the human race was first filling in the periodic table. We knew certain elements, the ones we didn't know we cold speculate about their size, weight, and properties, and usually we were very close once the real thing was found.

Also, if you want to know how hard it is for something to fossilize, take any animal carcass you want, rat to elephant, go anywhere in the world and either place it on the surface of the dirt or let it sink in any body of water as if it just died there. Now guarantee it will fossilize (first of all that it won't be scavenged, a huge hurdle right off the bat) and be there 100 million years from now. Not so easy by any stretch of the imagination. Its pure happenstance that anything fossilizes.

They have evolved into different species. Why do you think they are so different in the first place?

ARE YOU PEOPLE REALLY THIS STUPID?

I AM ASKING HOW ONE SPECIES CAN PRODUCE GENETICALLY INCOMPATIBLE, BUT VIABLE, OFFSPRING. ARE THESE WORDS TOO BIG TO UNDERSTAND?

P.S. "OVER MILLIONS OF YEARS" IS NOT AN ANSWER TO THIS QUESTION!

P.P.S. I AM NOT TALKING ABOUT INTRASPECIES ADAPTATION!!

GOOD GRIEF!!!

Your pc seems to be stuck on caps lock. Retype and try again, otherwise it looks like you are demanding something and that dog don't hunt Pinky.

The average step is 2.6 feet. There are 2445.43 miles between New York and Los Angeles. That means there are 4,966,104 steps between NY and LA.

What you are asking is the equivalent of - why when I take 1 step starting in NY have I not arrived in LA.

It is as easy as that to understand, but he and others won't understand it because they cannot conceive of 'deep time'. Millions of years and very gradual change. VERY gradual.

C'mon folks! Dog have evolved. They are now innately capable of training their human pets.

Same reason a fish thought to have been extinct for a hundred million years has not changed - species don't evolve into other species.
