Anews article discussing the evolution of domestic dogs from wolves included this statement: "on its way from pack-hunting carnivore to fireside companion, dogs learned to love-or at least live on-wheat, rice, barley, corn, and potatoes." what is more scientifically accurate way to state what happened with dogs?
a) dogs were created at the same time as wolves.
b) being around humans represented an advantage, so wolves were able to take advantage of that by changing their digestion to be able to eat wheat, rice, barley, corn, and potatoes.
c) dogs mutated to be able to eat wheat, rice, barley, corn, and potatoes.
d) some wolves may have had variants in their digestion that allowed them to eat wheat, rice, barley, corn, and potatoes and so were able to survive with humans.

The correct answer will be option-D

Explanation:

The studies done by the scientist led to the conclusion that the doges were evolved from the wolves,

The interaction of the wolves with humans became symbiotic around 10000-15000 years ago when the wolves in search of food changed themselves and adapted to survive with humans.

The studies on the genes of Dog shows that the gene responsible to digest carbohydrate called amylase starting duplicating in Wolves allowing them to digest carbohydrate cereals offered by humans. Their pancreatic enzymes also got modified to digest the carbohydrate-protein rich cereals.

Thus, option-D is the correct answer.

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.
