Best to adopt a different term entirely. I find it clear and informative and the opposite of tendentious. Walter White, several very minor details that have no bearing whatsoever on the point of this post. The reason for so few is because of how the color line opened up two options.
But when Francis Crick, co-discoverer with James D. Watson of the double helix structure of DNA, was asked what unraveling the chimpanzee genome would tell us about human differences he replied: The dog genome, Crick went on, would be a better target—because dogs vary so widely in appearance and behavior that unraveling their DNA would reveal much more about the influence of genes.
Canine evolution, because of dog breeding, has been run in fast forward—in some cases, before our very eyes. In an informative experiment, Dmitry Balyaev selectively bred foxes [PDF] to show neither fear nor aggression when approached by humans.
But the foxes changed in more than just their behavior. And a recent study by the Max Planck Institute has demonstrated that that in certain cognitive tasks our canine best friends are more like us than are our simian nearest relatives.
Fourteen-month old humans and almost any dog, but not even the brightest chimp, can use human pointing as a cue to find a food reward.
Researchers Brian Hare and Mike Tomasello concluded [PDF] that this ability is heritable and due to recent selection, since wolves cannot do it.
Dog breeds provide the classic case study of within-species differentiation. Those who would dismiss race and race differences regularly point out that DNA differences between races are minimal. Butas Vincent Sarich demonstrated in Race: The Reality of Human Differences pp.
They are around ten times the difference between the sexes within each race and larger than the differences that distinguish the two species of chimpanzee. Despite minimal genetic differences, human physical racial differences are clearly observable.
But only recently has genetic analysis been able to distinguish between breeds—or even between dogs and wolves. Unfortunately, this has been true even in scientific circles. And that in itself is instructive. The classic study was carried out by Daniel G.
Freedman for his doctoral dissertation. Freedman spent every day and evening rearing four dog breeds—Beagles, Wire-haired Fox Terriers, Shetland Sheepdogs, and Basenjis—from age two to twelve weeks.
Little Beagles were friendly from the moment they detected him. Shetland Sheepdogs were the most sensitive to a loud voice or the slightest punishment. The Wire-haired Fox Terriers were so tough and aggressive, even as clumsy three-week olds, that Freedman had to wear gloves in playing with them The Basenjis, barkless dogs from central Africa, were aloof and independent.
But originally breeds were selected to excel in certain elements of the basic wolf-dog ethogram [behavioral repertoire] and reduce or eliminate others. All of these differences, including the barklessness of the Basenji, make perfect sense in terms of what we know about the traits for which the different breeds were, or were not, selected.
Beagles are scent hounds.The social construction of gender is a notion in feminism and sociology about the operation of gender and gender differences in societies.
According to this view, society and culture create gender roles, and these roles are prescribed as ideal or appropriate behavior for a person of that specific sex.. Some supporters of this idea argue that the differences in behavior between men and women.
The advent of agriculture was a watershed moment for the human race.
It may also have been our greatest blunder. Essay Race As A Social Construct - The concept of race is an ancient construction through which a single society models all of mankind around the ideal man. This idealism evolved from prejudice and ignorance of another culture and the inability to view another human as equal.
A longstanding orthodoxy among social scientists holds that human races are a social construct and have no biological basis. A related assumption is that human evolution halted in the distant past.
Mar 04, · Constant exposure to people who see race as a fluid concept — who define themselves as Asian, Hawaiian, black or white interchangeably — makes rigid thinking about race . Sociologists, in general, recognize "race" as a social ph-vs.com means that, although the concepts of race and racism are based on observable biological characteristics, any conclusions drawn about race on the basis of those observations are heavily influenced by cultural ideologies.
