Chapter nine in Guns Germs and steel goes to describe how and where many of the domesticated animals in history came from, and how many of the larger species could not be domesticated and why. He uses the analogy of the Anna Karenina principle, that there are many reasons why an animal could be undomesticable, but in order for an animal to be domesticated, it must fit a multitude of requirements for it to be advantageous to use it in this way. He specifically refers to large animals, those over 100 pounds, and of those, only five species were used worldwide, and nine were used in specific geographies, this out of approximately 148 candidates throughout the world. Diamond then describes why most (13 of the 14) of the domesticated animals came
From this aspect, we can see that it was the development of science and technology rather than the natural selection that determines whether a species is able to be domesticated or not. Two forces were at work--- first, the human selection of the most useful animals, and second, the natural selection for the optimization in the huma n environments compared to the wild. This is the same as what he has discussed of plants. Nevertheless, Mcneill, on one hand, confirms that Diamond makes a good point Eurasia on east-west axis as opposed to north south continents, but he, on the other hands, doubts whether it should be as bid a part of development as Diamond makes it out to be, because in his view, geographic reductionism is radically out of fashion these
According to the novella Call of the Wild, Darwin’s proposition about survival of the fittest is correct in multitudinous approaches. Examples like Law of Fang and Law of Club are just some great indicators that only the most pertinent canines can abide whilst the weaker canines are either clubbed to death, died of
The indisposition that had scourged Darwin throughout his life began to direct him to the threshold of repose. Until his heartbreaking dissolution occurred on the 19th of April 1882, to a life that had so significantly affected the course of humankind. Before his tragic departure, Charles Darwin embarked on a fascinating voyage around the world on the HMS Beagle. Darwin 's studies of specimens around the globe led him to formulate his theory of evolution and his understanding of the universe that greatly increased scientific
The book “Darwin’s Doubt” by Stephen C Meyer attempts to negate the negativity surrounding the theory of intelligent design by giving a creationist’s perspective on the different issues surrounding the controversy and provide an argument for the legitimacy of intelligent design from a scientific and rational viewpoint. The book is broken into three different sections part one titled “The Mystery of Missing Fossils”, part two titled “How to build an animal” and part 3 titled “After Darwin. What?” Part one of the book focuses on the lack of validation and evidence hence the name “The Mystery of Missing Fossils” and gives a very brief introduction to the problems of missing fossils, missing phyla, and just general missing validation of the evolutionary
The other is “through influences which may occur more or less simultaneously but which, in any case, derive from different aspects of the total socializing environment” (121). This essay works well with Wayne Dennis’ article on the development of feral
For hundreds of years dogs have been purebred leading to health concerns. Even though dogs may look tougher, faster, or cuter, healthwise these purebred dogs are not as resilient to problems (Beuchat). This fact is the same for humans. When humans only marry into their close knit ethnic communities, their genetic deficiencies will be continuously passed on to future generations. Mutations, which come from random mating between species are valuable to future generations.
Early domestication was selecting for behaviours; such as decrease of aggression because they were seeking for wild power under their controls. Lately, DNA evidence shows that dog domestication has occurred in different cultures with different subspecies and later they
For example, two “Pitbulls” born from the same litter are given to two different owners; the first pup is brought up as a domestic, caring animal, able to coexist with humans of all ages and accustomed to sharing their living space with an array of animals of different species. On the contrary, the second pup is brought up as a fighting dog, up to an extent where the owner can no longer control the dog and it reaches a point where the dog is now so wild that it will attack humans and animals without an apparent cause. Although both pups are genetically equal up to a certain point and assuming they both share the genes responsible for tameness and domesticity, their distinct upbringings can still turn them into domestic or wild animals. Thus, implying that tameness, is just a unique quality that can be learned and passed on from species to species, rather than an inherited gene; It is an ability that can be improved and developed through example and
That wild animal of yours is unpredictable and not domesticated. The quote claims “Exotic animals are wild animals with wild animal instincts, even when born in captivity. A wild animal is never 100 percent predictable. An animal that has behaved one way for many years cannot suddenly change. Domestication is not something that happens in one or two generations: it takes hundreds or thousands of years” (Lewis).
I have also included an example of evolution in present times. This report will provide a better understanding of what evolution is about because different organisms have used to cover each section of this report. Evolution is continuous and so as changes in the environment occur, organisms will adapt in such a way as to adapt to these changes. Part One: Organism: Horses
Introduction The theory of evolution has been discussed, evaluated, and researched many times since the theory was first brought to light. Darwin’s theory of evolution is said to be divided into two parts, common decent and natural selection (Bouzat, 2014). Many research papers agreeing with Darwin’s theory comment on the diversity of a species and how they have descended from one common ancestor. Natural selection is a process in which species that are better adapted to the environment tend to survive and reproduce (Dictonary.com).
Evolutionary Biologist Stephen Jay Gould once discussed that evolution is the starting point of great realizations, “Evolution is a process of constant branching and expansion”. This statement has held true over many years, especially when looking into the tributes and trials the African Wild Dog has undergone to thrive and succumb to environmental pressures. The African Wild Dog (hereafter wild dog) is native to Sub-Saharan Africa. Being the only extant family member of Lycaon, the wild dog forms part of the Canis family due to its morphological characteristics.
Some of the traits become less notable dependent upon the environment the animal is placed in (Nurture)”. When observing a dog of a different breed one can see behaviour that can be identified as being specific to the breed. In mixed breed dogs the dominant genetic behaviour can be readily identifiable to a specific breed. Some dogs are very laid back, a child can pull on their ear and the dog just won’t react, this could be a genetic disposition. However if the same dog was beaten or traumatized in some way (Nurture) the dog may even bite the child.
Domestication is the taming of an organism to convert it to domestic use. Domestication however differs from taming in a sense that with domestication, both the behaviour and the physical characteristics of an organism can change. Domesticated organisms live in close contact with humans, mainly because they are beneficial to them. Domestication is the taming of an organism to convert it to domestic use. With domestication both the behaviour and the physical characteristics of an organism can change.
