Pros And Cons Of Artificial Breeding

1.5.2 Finch beaks
Many of you may have heard of the finch beaks of the Galapagos Islands which are so famously associated with Charles Darwin and his formulation of the theory of evolution by natural selection. Now, when this piece of information is analysed, it is incredible to consider that it is used as evidence for evolutionary theory and supposedly was instrumental in Darwin coming up with the theory of evolution and common descent. The story is that Darwin was on a voyage around the Galapagos Islands, and he observed various different types of finch birds over the separated Islands. He noticed subtle differences in the birds, particularly their beak sizes and shapes, and he found that the different types were located on different islands. …show more content…

the Great Dane’s and the Chihuahua’s descendants may no longer be able to technically reproduce with each other and would be determined new and distinct species. Now, let’s look at this point. Of course, this may be true but at present it is just a presumption. The fact is that all artificial breeding has shown so far is that certain characteristics of one species can be selected so that new variations within a species can be created which increases the diversity within that species. Artificial breeding has not been able to create a new species, therefore it has not shown that members of a species can evolve into another species. Subsequently, this is nowhere even close to acting as scientific evidence to support our default hypothesis. We want to know if a single-cell organism can turn into a man through a process of evolution, not whether certain traits of a species can be deliberately created or preserved. And, thinking about this logically, isn’t it likely that this would have been known even before the theory of evolution and artificial breeding, as people can see that offspring typically resemble a combination of both their parents? For example, tall parents are more likely to give rise to tall children, so similarly to artificial breeding in dogs, humans too can select certain characteristics and features by selecting their partner. If a dark skinned individual reproduces with a very fair skinned individual, it’s no great secret that their child is likely to have a mixed complexion which is dissimilar to both its parents. Also, is the variation seen within the dog species that remarkable? Okay, a Great Dane and Chihuahua might look miles apart but

Charles Darwin's Beak Lab Analysis: Natural Selection

336 Words | 2 Pages

Beak Lab Analysis Charles Darwin , a naturalist, discovered and stated that organisms arise and grow and develop through the natural selection. Natural selection is the process in which nearby organisms well adapted to the environment to survive and to produce offspring. In class we did a lab where we studied the amounts of food birds get with their different sizes of beaks. For an example, we use a spoon to represent a larger beak I found that it was harder to pick the food.

Scientific Concepts In 'The Beak Of The Finch'

391 Words | 2 Pages

Scientific Concepts in “The Beak of The Finch” On an island in the middle of a volcanic archipelago, where Darwin first created theories on the idea of evolution, Peter and Rosemary Grant spend twenty years proving that Darwin did not understand the power of evolution. I now understand better how natural selection, hybridization, and adaptation work in the real world. When I first took biology freshman year I didn’t quite understand how natural selection and evolution were real. But, as you read this book you begin to learn that natural selection is not a rare thing nor does it work slow.

Instead evolution had this bird develop a successful beak compared to other birds beaks. After the disaster the tweezys thrived then another round of natural selection and still came in seconds after the spoon mutated. Overall evolution made tweezys’ beaks different than others to see if they survived, and when they did, evolution would keep the beak type cycling around the

Compare Your Experiment Results In Better Flying Birds

818 Words | 4 Pages

Our neighbor's youngest bird was relatively similar to our youngest bird in the sense that both had a smaller front wing and a larger back one. They varied with small changes in wing size or position. However, overall the best flying shape among the groups we observed was a larger back wing and a smaller front wing. Predict the appearance of your youngest bird's descendants if… The selection conditions remain the same and the longest flying bird survives to produce the most offspring.

Great Bear Rainforest: Hazardous Or Carnivorous?

1545 Words | 7 Pages

After conducting extensive research, scientists have pulled DNA from the wolf scat, which has now provided convincing evidence that coastal wolves have unique genetic characteristics not found in their continental brethren. From all of the wolf research conducted the results have shown that there are about 35 different DNA haplotypes (DNA variation) in all of the global wolf populations(McAllister). Scientists are excited about the coastal wolves because they have found four or five haplotypes that haven 't been identified anywhere else on the continent. Just because they found these haplotypes in the rainforest wolves doesn’t mean that they aren 't found in other wolf populations, but it suggest that it is possible that these wolves have been evolving in isolation for a very

Golden Jackals Evolution

819 Words | 4 Pages

Canidae, the dog family, consists of 34 related species that diverged within the last 10 million years (Toh 2005). When humans migrated out of Africa, they came in contact with gray wolves; somes wolves were domesticated and through many generations, the modern-day dogs emerged (Freedman 2014). A close distant cousin of the dogs and wolves are the golden jackals, canis aureus. Golden jackals were first reported in Croatia in 1491 (Fabbri 2013). The golden jackals are spread out from most of Europe, to northern Africa and parts of Asia (Arnold 2012).

El Patron Character Analysis

When puppies are born from the same mother they tend to have similar traits such as color, birthmarks, and size. However, once they are separated, the experiences and type of owner they have will result in them being completely different dogs. This is an example of nurture dominating nature. Experiences determine who a person is growing up, not genetics. The way someone is raised, the type of schooling they have, and the friends they have all determine what type of person someone will be once they are grown up.

Dog breeds, what are they? Defined by the American Kennel Club Association or the AKCA a dog breed is a domestic race of dogs (selected and maintained by man) with a common gene pool and characterized appearance and function. So what does that really mean? Breeds of animals is actually a very hard definition to deter, but a common definition easy for us to understand is that a breed of dogs is when a dog looks like another in some cases how when we see a chihuahua we automatically call it a chihuahua without actually finding out. Is pre-determining a breed by looks bad after all?

However, recent studies suggest that many of the physical changes in dogs may have occured spontaneously. So as amazing as it is, it seems dogs have actually evolved along the lines they believe we expect of them. Now that's what I call devotion! Fascinating stuff, but there's also a practical purpose to all this. Let's say you are interested in buying or adopting a purebred dog.

This lack of mental maturity in dogs makes them more aggressive than wolves since aggressiveness is the most common defense mechanism of animal young in the wild. Furthermore, if tameness and aggression are genetic traits this retrogression from domestic to wild animal would not be possible, despite the several similarities shared between wolves and dogs, because genetically dogs represent one

Thinking further and associated his observations with all these theories, which made more sense. Darwin observed that there were thirteen types of finches and the only differences between them were their beaks and that they each were suitable for the type of food they ate. Also observed, traits from parents can be passed to their offspring. The organisms had more offspring that their environment could “handle”. He noticed that resources were running out and that caused competition between groups.

What Are The Arguments Against Darwin's Theory Of Evolution

There are a least 14 species of Darwin’s finches that have developed over millions of years. When Darwin encountered the finches on the Galapagos Islands he noticed the diversity of the Finches beaks and size compared to each other. In Figure 1 you can see this. The diet of nuts and berries that the finches had access to on the island is greatly related to the size and function of the finches beaks (Grant, 2003). The larger beaked birds fed off of hard shelled nuts, while the smaller beaked birds fed off of smaller seeds and nectar from plants.

Nature Vs Nurture Theory Of Human Behavior

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.
