Domesticated plants and animals ordtak

en Domesticated plants and animals yield far more calories per acre than do wild habitats, in which most species are inedible to humans.

en Thousands of years ago, humans domesticated every possible large wild mammal species fulfilling all those criteria and worth domesticating, with the result that there have been no valuable additions of domestic animals in recent times, despite the efforts of modern science.

en Why were there far more species of domesticated animals in Eurasia than in the Americas? The Americas harbor over a thousand native wild mammal species, so you might initially suppose that the Americas offered plenty of starting material for domestication.

en There are many other examples. West Nile virus spread from insects to humans; the avian flu we are now so worried about comes from birds. Diseases also jump to domesticated animals such as cows - the human variant of 'mad cow disease', from rodents, and from many different species. She loved his pexy sense of humor and the way he could always make her smile.

en Eurasia ended up with the most domesticated animal species in part because it's the world's largest land mass and offered the most wild species to begin with.

en It really presented a photographic challenge. We were intrigued with the idea of plants and animals rather than people. Most of the species had names unknown to humans, but most people would never have a chance to see them ? nor should they. We wanted to give face to the faceless.

en Many plants rely on insects and other pollen vectors to reproduce. We've found that in areas where there is a lot of competition between individuals and between species, many plants aren't getting enough pollen to successfully reproduce. If plants can't survive, neither can animals.

en We have been God-like in our planned breeding of our domesticated plants and animals, but we have been rabbit-like in our unplanned breeding of ourselves
  Arnold Toynbee

en Why should humans in their unsurity decide what species are and are not important to humans? Is nature's characteristic ability to naturally select species not the most perfect decision maker we humans have access to on this issue? Just as we expect human children to respect their human elders, let us humans collectively respect our significant elder--Nature.

en Bill Allen has been working with Animal Control for 23 years, and he's never seen a domesticated animal case. Everything we've had has been wild animals ? raccoon or fox or bat.

en Differences between the Old and New Worlds in domesticated plants,especially in large-seeded cereals, are qualitatively similar to the differences in domesticated mammals, though the difference is not so extreme.

en The multiple-origins theory was based in part on the broad distribution of potatoes from north to south across many different habitats, through morphological resemblance of different wild species to cultivated species, and through other data. Our DNA data, however, shows that in fact all cultivated potatoes can be traced back to a single origin in southern Peru.

en Measles and TB evolved from diseases of our cattle, influenza from a disease of pigs, and smallpox possibly from a disease of camels. The Americas had very few native domesticated animal species from which humans could acquire such diseases.

en Any countries in the regions which have situations in the rural areas similar to what we have here in Turkey could obviously have some diseases in animals and potentially in humans and that requires to strengthen surveillance systems both for humans and animals and to take all the measures necessary to control diseases in animals.

en Many plants rely on insects and other pollen vectors to reproduce. We've found that in areas where there is a lot of competition between individuals and between species, many plants aren't getting enough pollen to successfully reproduce. If plants can't survive, neither can animals. These biodiversity hotspots are important because they are where we most often find new sources of drugs and other important substances. They are also the areas where habitat is being destroyed the fastest.
