Darwin was a naturalist and geologist who was best known for his work on the Galapagos Islands. The Galapagos Islands are off the coast of Ecuador. When Darwin was on the islands, he noticed many finches. Also, each island had a distinct group of finches, different from the ones on the other islands based on their beaks. This is where he got his idea for natural selection. He concluded that all the finches must have originated from one species in Ecuador, and that some must have flown to the islands. Some groups might have stayed on one island, and other groups on other islands. This is where the beaks mattered for the finches. Since each island had different sources of foods, the finches had to have specific beaks in order to get the food. …show more content…
If finches had short beaks, then they would struggle to get nectar. In this case, the long beaked finches are better adapted to their environments, meaning they have higher chances of surviving and passing their genes onto their offspring. The short beaked finches would have a disadvantage, and would struggle to survive and reproduce. Over time, the finches better adapted would strive in their environments and their population would increase, while the finches with disadvantages would most likely die off. This is natural selection. Moreover, the finches that survived on each island would evolve to be better suited to their environments. Eventually, the groups of finches would separate into their own species. Darwin's idea of natural selection was that plants and animals best suited to their environments will survive to reproduce, and the weak ones will die off over
Juana Villegas v Metropolitan Government County/Nashville-Davison County Sheriff’s Office Juana Villegas, 9 months pregnant with her fourth child, was arrested and detained for pretrial on a minor traffic offence on July 3,2008. After two days in the Davison County detention center, Ms. Villegas’s water broke and she went into labor. She was transported by ambulance to Metro General Hospital, before transport she was handcuffed and shackled, at that time an officer from the detention center noted his concerns. According to the testimony of Dr. Sandra Torrente, the concern was reasonable given the history of Ms. Villegas’s short labors; in fact, once the restraints were removed, she progressed from 3cm.
In Biology class we conducted a lab called “Bird Beaks”, in the lab we were separated into four groups of different bird beaks. Our goal was to see which type of beak was more successful, and if evolution occurred. I claim that Evolution did occur in the bird beak lab because spoons were able to survive and grow throughout everything that occurred and tweezys were able to grow and thrive after migration and everything that followed. My first piece of evidence and reasoning, is that spoons survived throughout the whole experiment after two natural selections, a migration of tweezys, a natural disaster, and a mutation. We started with seven spoons and ended with thirteen spoons.
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.
TKAM/Scottsboro- Final Paper Racism has been a major social issue in our modern world. From many years ago to today, there has been discrimination among many. Nine young african american men were accused of rapping 2 white women in 1931 (Scottsboro Boys) and a black man was accused of rape in To Kill a Mockingbird. The men were falsely convicted due to the fact that they were black men and the victims were white women.
Quote: “There was some law the birds obeyed, and it had to do with the east wind and the tide.” (Du Marier 12). Analysis: Every time the birds are gone, he knows he can go outside and do some work for a few hours to make the house better at keeping the birds out. This is smart because he also knows when the birds are coming and when they are attacking the most. Follow Up: So, by the end of the story, this knowledge led him to survive longer than the
Overall, Darwin knew that species were transforming and evolving over
This feeding mechanism can be explained partially by the bird’s beak shape and size. The Chickadee has a short conical beak allowing it to peck into shell and feed on the inside. Yet it is also conical and comes to a point allowing it to grab insects. Thus the Chickadee tends to forage in locations with ample berries, seeds or insects. This diet partially explains why the Chickadee prefers White Oak (Hemert et al, 2012).
Only the offspring with certain traits that were suitable with the environment survived. This led him to believe that species evolve from a common ancestor because he saw that many organisms had similar traits and that they eventually accommodate to their surrounding
Later he found them first one, then two and a third and fourth- four lifeless baby sparrows, scattered in the short grass where they had been thrown from their nest. Matted fuzz covered the twisted little bodies. Two had died with their big yellow beaks open as if searching for food. The other two lay facing their nest, their necks reaching out.

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.
When insects became abundant, finches have developed smaller and longer beaks.
When forced to leave one habitat or environment on the island for nature or naturalist causes whether that be: interspecies competition or lack of resources the birds in response were able to adapt such that they could survive and their species would not die off. This was an immediate response to a subtle change in climate (sand and sun to water and rain forest) that was not predetermined, for theses
On his numerous explorations, he would spend countless hours searching, recording and comparing animals he saw from one place to another. His encounters with the varied species on the Galapagos Islands gave Darwin the ideas and the evidence to support his theory. The people he met along the way encouraged him to observe and publish his work. Additionally, once his theory was known, people took his ideas, making new ones, sparking the exchange of other theories and ideas. Therefore, as a result of his extensive research and exploration of the Galapagos Islands through the different encounters of people and various species, Charles Darwin formulated his theory supported by
Charles Darwin was an incredibly influential scientist whose Theory of Evolution changed the scientific community forever. His theory assumes that all of life evolved from one common ancestor. He also came up with the concept of Natural Selection, a topic that we often have discussed in class in context to the evolution of different species. Natural Selection is, simply put, the idea that genetic mutations that have evolved to benefit a species are the ones that will remain in the species over time. Natural Selection will pick off the individuals with genetic mutations that don’t benefit the species and ensure that the gene pool is filled with largely the individuals with beneficial mutations for the survival of the species.
