Instead, he says they discovered a technical glitch behind the findings supporting two domestications, which they reported in their study today.

"For right now, I can't think of another way of actually explaining all this information altogether, besides suggesting that there were two domestications," he says.

A claim of multiple domestications for dogs requires extraordinary evidence, says study coauthor Krishna Veeramah, an evolutionary geneticist at Stony Brook University in New York.

These new data don't completely rule out multiple domestications (the single event is just the simpler explanation), nor do they indicate where humans and canines became BFFs, Veeramah says.

The evidence shows that this isn't true: there's an enormous gap—four thousand years—separating the "two key domestications," of animals and cereals, from the first agrarian economies based on them.

The relationships between these populations is still unclear, but with the help of the Bronze Age Newgrange dog's genome, Frantz's team has shown that they likely did not significantly intermingle until many millennia after their unique domestications.

Pogo, also known as Tigger in humans, has been domesticated by humans and yeast alike into the CENPB gene. Other human domestications of pogo include TIGD1, TIGD2, TIGD3, TIGD4, TIGD5, TIGD6, TIGD7, JRK, JRKL, POGK, and POGZ.

Chenopodium giganteum belongs to the same genus as quinoa or Chenopodium album. Many species of this genus have a long history of domestications as grain, vegetable or forage crops. Therefore, genetic relationships and place of origin are hard to determine. Chenopodium giganteum has two main subspecies one origin form India the other from America.

As plant species sharply declined, humans migrated to the fertile Niger River bend region, with abundant resources including plants for grazing and fish. Like in the Fertile Crescent, many food crops were domesticated in the Niger River region, including yams, African rice (Oryza glaberrima), and pearl millet. The Sahara aridification may have triggered, or at least accelerated, these domestications.

This latter ritual in particular, is a unique feature of the south Indian neolithic and has resulted in the formation of large ‘ashmounds’ up to 30 feet high at various places.

Genetic studies have shown that all dogs are descendants from the gray wolf, however, it is currently unknown when, where, and how many times dogs were domesticated. Some genetic studies have indicated multiple domestications while others have not. Archaeological findings help better understand this complicated past by providing solid evidence about the progression of the domestication of dogs. As early humans domesticated dogs the archaeological remains of buried dogs became increasingly more abundant.

Recent research in the early 21st century has modified this view somewhat; scholars now indicate the adjacent Balsas River Valley of south-central Mexico as the center of domestication. An influential 2002 study by Matsuoka et al. has demonstrated that, rather than the multiple independent domestications model, all maize arose from a single domestication in southern Mexico about 9,000 years ago. The study also demonstrated that the oldest surviving maize types are those of the Mexican highlands.

Because of the wide range of crops developed from the wild B. oleracea, multiple broadly contemporaneous domestications of cabbage may have occurred throughout Europe. Nonheading cabbages and kale were probably the first to be domesticated, before 1000 BC,Katz and Weaver, p. 284 perhaps by the Celts of central and western Europe, although recent linguistic and genetic evidence enforces a Mediterranean origin of cultivated brassicas. While unidentified brassicas were part of the highly conservative unchanging Mesopotamian garden repertory,"Cabbage plants" are mentioned by A. Leo Oppenheim, Ancient Mesopotamia: Portrait of a Dead Civilization rev. ed.

At least 11 separate regions of the Old and New World were involved as independent centers of origin. Some of the earliest known domestications were of animals. Domestic pigs had multiple centres of origin in Eurasia, including Europe, East Asia and Southwest Asia, where wild boar were first domesticated about 10,500 years ago. Sheep were domesticated in Mesopotamia between 11,000 BC and 9000 BC. Cattle were domesticated from the wild aurochs in the areas of modern Turkey and Pakistan around 8500 BC. Camels were domesticated late, perhaps around 3000 BC. Centres of origin identified by Nikolai Vavilov in the 1930s.

Time-lapse video of mung beans germinating over 10 days The mung bean was domesticated in India, where its progenitor (Vigna radiata subspecies sublobata) occurs wild. Carbonized mung beans have been discovered in many archeological sites in India. Areas with early finds include the eastern zone of the Harappan Civilisation in modern-day Pakistan and western- and northwestern India, where finds date back about 4,500 years, and South India in the modern state of Karnataka where finds date back more than 4,000 years. Some scholars, therefore, infer two separate domestications in the northwest and south of India.

The domestication of barley probably occurred around 10,000 years ago in the Israel and Jordan region of the Fertile Crescent. Barley grains have been found at a number of archaeological sites in this area and the wild barleys here are more molecularly similar to the cultivated gene pool than are any other wild populations. AFLP technology indicates single domestication of barley, not, as had previously been hypothesized, a series of domestications in different parts of its range such as in Ethiopia and in the Mediterranean region. Further research using haplotype frequency in different geographic parts of the range led to the inference that there were at least two domestication events, one in the Fertile Crescent and another some further east.

Native Oaxaca criollo avocados, the ancestral form of today's domesticated varieties Persea americana, or the avocado, possibly originated in the Tehuacan Valley in the state of Puebla, Mexico, although fossil evidence suggests similar species were much more widespread millions of years ago. However, there is evidence for three possible separate domestications of the avocado, resulting in the currently recognized Mexican (aoacatl), Guatemalan (quilaoacatl), and West Indian (tlacacolaocatl) landraces. The Mexican and Guatemalan landraces originated in the highlands of those countries, while the West Indian landrace is a lowland variety that ranges from Guatemala, Costa Rica, Colombia, Ecuador to Peru, achieving a wide range through human agency before the arrival of the Europeans. The three separate landraces were most likely to have already intermingled in pre-Columbian America and were described in the Florentine Codex.
