i got a script for cialis and my dick stays hard as rock.

bitch ,call that well prepared!

[!DoNkE*PuNchA!]

No masterbating before sex, so you can last longer. Is being prepared.

and the cialis is cool to except when her friend walks in and your face is the color of "neg" and feels like its on fire.

SCIENTIFIC METHOD / SCIENCE & EXPLORATION

Where did dogs come from? It turns out we don't really

know

Dogs were the very first creatures that humans domesticated,

and their remains have been found along with those of

humans from before we even had basic things like agriculture.

And, with the advent of molecular tools, researchers were able

to identify the animal that was domesticated (the gray wolf), as

well as a handful of breeds that appear to be "ancient," and

split off close to the source of domestication.

It was a nice picture, but apparently it was probably wrong.

That's the conclusion of a study that appeared in this week's

PNAS, which uses a combination of genetic, archeological, and

historic evidence to argue that the history of domestic dogs is

such a mess that we're not going to be able to unravel it

without resorting to large-scale genome sequencing efforts.

The challenges of sorting out what happened from

archeological remains are significant. The source of

domesticated dogs, the gray wolf, historically ranged across all

of North America, Europe, and Asia. The earliest domesticated

dogs, which appeared about 15,000 years ago, looked a whole

lot like the wolves they were descended from, making

unambiguous identification of domestic vs. wild animals a

challenge. And once things that were clearly dogs started

appearing, they appeared over a huge geographic range. The

earliest remains appear in Europe, the Middle East, and

Kamchatka (on Russia's Pacific coast) all within 1,500 years of

each other. Within another thousand years after that, domestic

dogs were present in North America, as well.

It's impossible to tell whether these distant sites represent

separate domestication events, or whether (and, if so, how

often) the earliest domesticated dogs ended up breeding with

wolf populations.

All of that would seem to make DNA testing the best way to

bring some clarity. And, indeed, the authors have a prodigious

amount of data at their disposal, having looked at nearly 50,000

individual variations in DNA sequences, using a population of

1,375 dogs and 19 wolves. As with past studies, these identified

a handful of breeds as "ancient," meaning they appear to have

branched off the family tree much closer to the domestication

event. These breeds are the Akita, Basenji, Eurasier, Finnish

Spitz, Saluki, and Shar-Pei (more on the Eurasier later).

But the authors themselves point out that there's a problem

with their own data: none of these breeds are from the regions

where the first remains of domesticated dogs are found, and a

few come from outside the normal range of the grey wolf. In

fact, the archeological evidence suggests that some of the

genetic data can't be trusted at all. As far as we can tell, dogs

spread across the Pacific only 3,500 years ago, but two breeds

(Dingoes and New Guinea Singing Dogs) from there appear

near the base of the tree. The same thing goes for Southern

Africa, where dogs arrived less than 1,500 years ago, but a

specific breed (Basenjis) looks ancient.

What in the world is going on here? The authors argue that it's

a product of the odd history of the domestic dog. For one, we

can largely throw out any genetic data from the Americas.

Everything we have from there indicates that dogs were

brought over in such large numbers by European colonists that

they swamped out any breeds native to these regions. (In fact,

a hairless mutation found in a breed "native" to Mexico is

identical to that found in breeds in China.)

In Europe, most breeds aren't original. For example, the Irish

Wolfhound has been proposed as being an old one, but wolves

were already hunted to local extinction before 1800, and the

original version of the breed probably died out shortly

afterwards. (The current incarnation is probably the product of

a recent attempt to revive the characteristics through selective

breeding.) Similar things apply almost everywhere else; most

breeds have probably only been around 300 years or less. And

then both World Wars created large bottlenecks; many breeds

were reduced to a handful of individuals, and some probably

vanished entirely (only to be rebred since).

This process of rederiving breeds has made matters worse. In

some cases, we know exactly how a breed came about. As the

authors note, Eurasiers looked ancient, but were recently

derived from a mix of Chows, Keeshonds, and Samoyeds. But

all of these breeds come from near the base of the dog family

tree. As a result, Eurasiers look like an ancient breed

themselves, even though we know they're not.

The authors conclude that the breeds that appear ancient

haven't actually split off from the dog family tree early. Instead,

they've simply remained isolated during the massive shuffling

and rederivation of breeds that has been taking place over the

last few hundred years. That shuffling has made everything else

look older, so that a breed that has only been isolated for a few

thousand years suddenly looks ancient.

Will we ever sort this all out? The authors argue that the advent

of cheap DNA sequencing could give us enough data to start

pushing the resolving power back. But that would require that

we decide knowing more about the dog's history is worth the

resources required to do this sequencing.
