The Finches From The Galapagos Island - 1255 Words

Change is the key factor in a species survival, whether that change, is being minimal or extremely dramatic, and without change a species have condemned itself to extinction. Animals have learned to adapt to their surroundings in order to survive, and with these adaptation people can witness new breeds added to the spectrum and see them flourish. Breeds can be defined as a stock of animals or plants within a species having a distinctive appearance and typically having been developed by deliberate selection. For example the finches from the Galapagos Island’s they are all finches, but they all differed in their appearance, some had smaller others had larger beaks. Charles Darwin studied these Finches and came to discover that the Finches differed in appearance because they had adapted to their environment. The Galà ¡pagos finches provide an excellent example of this process. Among the birds that ended up in arid environments, the ones with beaks better suited for eating cactu s obtained supplementary food. As a result, they were in healthier condition to mate. Similarly, those with beak shapes that were well suited in getting nectar from flowers or eating thicker shielded seeds in other environments were at an advantage there. In a very real sense, nature selected the best adapted varieties to survive and to reproduce. With his findings throughout the years Darwin formulated his theory of evolution by natural selection, and published his first book entitled, On the OriginShow MoreRelatedThe Galapagos Islands1539 Words   |  7 PagesThe Galapagos Islands The Galapagos Islands are a group of 16 islands located in the Pacific Ocean that straddle the equator about 525 miles west of the South American Coastline. The islands were formed by underwater volcanoes millions of years ago and belong to Ecuador. The Galapagos are well known for their vast diversity in plant and animal populations. Some of the plant and animal life found on the islands cannot be found anywhere else in the world.

For centuries, this chain of volcanic islands has been used uniquely by various cultures based off distinct needs. What has remained the same however is the fact that island isolation has forced many animal and plant species to adapt differently from one anothe r based off their island’s environmentalRead MoreCharles Darwins Life and Accomplishments784 Words   |  4 PagesDarwin had 10 children.

He was the second youngest of six children. Darwin came from a great long line of scientists. His father, Dr. R.W. Darwin, was as a medical doctor, and his grandfather, Dr. Erasmus Darwin, was a distinguished botanist. Darwin’s mother, Susanna, died when he was only 8 years old. Darwin was a child of lucre andRead MoreThe Natural History of the Galapagos Written by Ian Thornton1150 Words   |  5 Pagesof biology. The following is based on the book â€Å"The Natural History of the Galapagos,† written by Ian Thornton. Darwin came up with the theory of evolution after he had spent time in the Galapagos Islands. While he was in the Galapagos Islands Darwin had noticed a specific breed of birds, these birds were known as the Galapagos Finches. What Charles had specifically noticed about the Galapagos finches was that the finches were made up of many different species; it was obvious that these birds wereRead M oreThe Theory Of Christianity And Christianity1321 Words   |  6 Pagesor the rising and setting of the sun. Our ancient ancestors at the dawn of humanity were in a huge and confusing world, obviously trying to make sense of it all. This beginning of our intellectually adept species had no people before them to learn from, and formulated simple theories that could easily explain everything. The idea of a higher being, a deity, was an easy concept to grasp. Some of the very early creationist theories were centered on a polytheistic foundation. Polytheism was the cornerstoneRead MoreAdaptive Radiation And Species Diversification1490 Words   |  6 PagesThe population of an ancestor species radiates outwards to different ecological niches. From there, these now separate populations adapt to their new habitats and resources in isolation. This gives them opportunity to evolve and become their own species based off of genetic changes that make them most fit for their new environments. Examples of these kinds of adaptations derive from geographic isolation from other species, reduction of gene flow among the populations, and the occurrence of sexualRead MoreCharles Darwin s Theory Of Biblical Creation1028 Words   |  5 PagesIn 1831 Charles Darwin graduated from Cambridge, with a Bachelor of Arts Degree, yet Darwin was far more interested in geology and biology. Taking a drastic turn in his studies, Darwin became fascinated in the scientific findings of geologist Adam Sedgwick and the naturalist John Henslow. Prior to the expedition, Darwin, along with his mentors rejected biological evolution. Darwin s mentor, Henslow, was able to secure a spot for Darwin on the H.M.S Beagle.

However, most scientists in the scientific community do not accept the concept or theory of intelligent design. Moreover, they consider it to be an argument from ignorance because it relies upon a lack of knowledge for its conclusion: Lacking a natural explanation, we assume intelligent cause (Scott Branch, 2002). Most scientists would agree that what cannot be currently explained now is not unexplainable
