Context paragraphs:
Origin of the domestic dog: The origin of the domestic dog is not clear.  The domestic dog is a member of genus "Canis" (canines) that forms part of the wolf-like canids, and is the most widely abundant carnivore.  The closest living relative of the dog is the gray wolf and there is no evidence of any other canine contributing to its genetic lineage.  The dog and the extant gray wolf form two sister clades, with modern wolves not closely related to the wolves that were first domesticated.  The archaeological record shows the first undisputed dog remains buried beside humans 14,700 years ago, with disputed remains occurring 36,000 years ago.  These dates imply that the earliest dogs arose in the time of human hunter-gatherers and not agriculturists.  The dog was the first domesticated species.

Domestication of animals: The domestication of animals is the mutual relationship between animals with the humans who have influence on their care and reproduction.  Charles Darwin recognized the small number of traits that made domesticated species different from their wild ancestors.  He was also the first to recognize the difference between conscious selective breeding in which humans directly select for desirable traits, and unconscious selection where traits evolve as a by-product of natural selection or from selection on other traits.  There is a genetic difference between domestic and wild populations.  There is also such a difference between the domestication traits that researchers believe to have been essential at the early stages of domestication, and the improvement traits that have appeared since the split between wild and domestic populations.  Domestication traits are generally fixed within all domesticates, and were selected during the initial episode of domestication of that animal or plant, whereas improvement traits are present only in a proportion of domesticates, though they may be fixed in individual breeds or regional populations.

Capsicum pubescens: Capsicum pubescens is a species of the genus "Capsicum" (pepper), known in Peru as rocoto (Quechua, rukutu, ruqutu), locoto in Bolivia & Argentina (Aymara, 'luqutu') and as the "Manzano" pepper in Mexico which means "apple" for its apple-shaped fruit.  This species is found primarily in Central and South America, and is known only in cultivation.  The species name, "pubescens", means hairy, which refers to the hairy leaves of this pepper.  The hairiness of the leaves, along with the black seeds, distinguish this species from others.  As they reach a relatively advanced age and the roots lignify quickly, sometimes they are called tree chili.  Of all the domesticated species of peppers, this is the least widespread and systematically furthest away from all others.  It is reproductively isolated from other species of the genus "Capsicum".  A very notable feature of this species is its ability to withstand cooler temperatures than other cultivated pepper plants, although it cannot withstand frost.

Agriculture: Agriculture is the cultivation and breeding of animals, plants and fungi for food, fiber, biofuel, medicinal plants and other products used to sustain and enhance human life.  Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that nurtured the development of civilization.  The study of agriculture is known as agricultural science.  The history of agriculture dates back thousands of years, and its development has been driven and defined by greatly different climates, cultures, and technologies.  Industrial agriculture based on large-scale monoculture farming has become the dominant agricultural methodology.

Dog: The domestic dog ("Canis lupus familiaris" or "Canis familiaris") is a member of genus "Canis" (canines) that forms part of the wolf-like canids, and is the most widely abundant carnivore.  The dog and the extant gray wolf are sister taxa, with modern wolves not closely related to the wolves that were first domesticated, which implies that the direct ancestor of the dog is extinct.  The dog was the first domesticated species and has been selectively bred over millennia for various behaviors, sensory capabilities, and physical attributes.

Cucurbita fraterna: Cucurbita fraterna, also known as Cucurbita pepo" subsp.  "fraterna, is a mesophyte plant species of the genus "Cucurbita".  It is native to Tamaulipas and Nuevo León, Mexico.  It has not been domesticated.  It is the progenitor and nearest relative of the domesticated species "Cucurbita pepo" and wild "C. pepo" is still found in the same areas as "C. fraterna".  It was formally described by Liberty Hyde Bailey in 1943, in "Gentes Herbarum".

Jane Hamilton-Merritt: Jane Hamilton-Merritt (born Mary Jane LaRowe, 1937), in Noble County, Indiana is a retired college professor, photojournalist, author, and animal rights and animal husbandry advocate.  She resides in Redding, Connecticut.  In 1999, she was inducted into the Connecticut Women's Hall of Fame.  Some of her work has focused on breeding and raising Llamas and Alpaca.

Genomics of domestication: Domesticated species and the human populations that domesticate them are typified by a mutualistic relationship of interdependence, in which humans have over thousands of years modified the genomics of domesticated species.  Genomics is the study of the structure, content, and evolution of genomes, or the entire genetic information of organisms.  Domestication is the process by which humans alter the morphology and genes of targeted organisms by selecting for desirable traits.

Emmer: Emmer wheat, also known as farro especially in Italy, or hulled wheat, is a type of awned wheat.  Emmer is a tetraploid (2n=4x=28 chromosomes).  The domesticated species are "Triticum turgidum" subsp.  "dicoccum" and "Triticum turgidum "conv."  durum".  The wild species is called "Triticum turgidum" subsp.  "dicoccoides".  The principal difference between the wild and the domestic species is that the ripened seed head of the wild species shatters and spreads the seed onto the ground, while in the domesticated emmer, the seed head remains intact, thus making it easier for humans to harvest the grain.

Alpaca: An alpaca ("Vicugna pacos") is a domesticated species of South American camelid.  It resembles a small llama in appearance.
