The Unknown Scientist:
“Mr. Behan reaches new heights in ignorance of evolution when he reworks the creationist lament, “Why ain’t monkeys turning into humans?
” He puts his own spin on it by asking:
“why then haven’t domesticated versions of foxes and coyotes, not to mention other dump scavengers such as rats, bears, raccoons, skunks, crows, ravens, seagulls, etc., etc., been domesticated through the same process that tamed the wolf?”
In simple terms, once an organism takes an evolutionary path in any direction, it’s hard to do a U-turn. No do-overs. And even under identical environments E.coli
will evolve into different strains.
“Even from so simple a beginning, small happenstances of history may lead populations along different evolutionary paths. A potentiated cell took the one less traveled by, and that has made all the difference.” (Lenski 2008)
The same is/was true for dogs.”
KB: The Unknown Scientist doesn’t know what I’m saying because The US doesn’t know what she/he’s saying. The Russian Fox breeding experiment is cited as evidence that the domestication of the dog occurred through selecting for the trait of approachability. When humans began living in settlements and concentrating waste in one spot, those wolves that were the last to leave when humans approached, and the first to return, evolved into the domesticated dog.
In short, friendliness is the defining variable of the domesticated dog. I discount this interpretation that approachability is the defining factor even though it can still be true that scavenging human refuse sites may prove to be the catalyzing event in the domestication of the dog (although the most recent evidence is trending in the opposite direction, see Mark Derr "How the Dog Became the Dog" for the counter argument). In point of fact dogs are far more aggressive than wolves and are able to perform far more complex work in service to human beings than can other domesticated animals. Meanwhile The US says that once an organism takes an evolutionary path in a certain direction, it can’t do a u-turn, and therefore my point is nullified because foxes, coyotes, raccoons and sea gulls were on a different evolutionary track from wolves so that they couldn't self-domesticate even given the selective pressure toward approachability from the largesse of human waste dumps. But this is actually a restatement of my thesis. In other words, the defining principle of a dog derives from the evolutionary track of wolves so that it could benefit from the largess of human dump sites. What makes a dog a dog remains its heritage from the wolf as a group hunter of a large dangerous prey animal, and so that's why the scavenging theory cannot account for the nature of the dog.
