America. While on the mainland of South America‚ Darwin observed a type of finch inhabiting the area. Darwin studied the finch specie and tried to look for different variations‚ but to no avail. Darwin observed no changes in the finches while on the mainland. However‚ this was not the case when he started exploring the Galapagos Islands. Darwin was quick to notice a variation in the species of finches‚ particularly in their beak area. The amazing part was that the finches were actually different from

Charles Darwin was basically forced to go to school and learn medicine to become a doctor by his father. At the age of 16 he was enrolled at the Edinburgh‚ Scotland as a medical student. He showed little interest in medicine and was horrified by the brutality of the surgery that was performed with no anesthesia or pain relief‚ as anesthesia wasn’t used for

Although Charles Darwin was not the founder of the Galapagos Islands‚ he is considered “the most celebrated visitor to Galapagos”. He arrived on board the HMS Beagle in 1835 on his way home after charting the coasts of South America from the Rio Plata round to Chiloe in Southern Chile. It was on the Galapagos that Darwin stumbled upon many diverse life forms. (Finch‚ n.d.) The beauty and uniqueness Charles Darwin recognized

Darwin also noticed that all of the finches varied in beak size and shape‚ and that they were associated with various diets based on different foods. He concluded that when the original South American finches reached the islands‚ they dispersed into different environments where they had to adapt to different

America as Darwin being an amateur. Instead of Darwin spending five years just in the sea he decided he wanted to explore the lands. One specific animal that grabbed Darwin’s attention was the finch bird. He noticed that on every island he would go each species of finches were different especially their` beaks. He then took examples of the different bird species and took them back with him to the museum of London. Darwin never valued the little differences between the finches until John Gould did and

Evolution vs. Creationism: Disproving The Theory of Evolution Since the 19th century‚ biologists have questioned the origin of life‚ asking the question "How did life first begin?" To answer that question‚ they have come up with two contradicting yet plausible theories‚ Creation and Evolution. The theory of Creation states that an intelligent being designed each organism. On the other hand‚ the theory of Evolution states that some form of stimuli sparked one of the earliest forms of life and
