Saguaro National Park is located in Tucson, Arizona. The park is split into two parts called districts. The first one being the Eastern Rincon Mountain District, rising over 8,000 feet and having over 128 miles of trails. The Western Tucson Mountain District is almost level with a dense saguaro forest. Even though Saguaro National Park is in the middle of the desert, there is a lot of information to be learned in the vast lands of sand and…
By capturing Atahualpa at Cajamarca, the conquistadors had essentially defeated the Incas. Without its leader, the rest of the empire fell easily. Pizarro demanded a massive ransom for Atahualpa, consisting of an entire room filled with silver and gold. He then executed him, replacing him with a puppet ruler. Although several rebellion attempts occurred over the next 40 years, all were unsuccessful, and the Spanish finally colonized the region in 1572 as the Viceroyalty of Peru.…
The Beak of the Finch by Jonathan Weiner explores evolution through the most famous examples in history—the finches of the Galápagos Islands. Charles Darwin’s theory of natural selection and the process of evolution are applied directly to what scientists refer to as Darwin’s Finches. Weiner follows scientists Peter and Rosemary Grant as they study the finches in real time on the Galápagos. Years of previous work, study and data is collected and analyzed. Different species of animals are observed and explained throughout history. The Grants have one goal, and that is to find the origin of the species, how organisms first began. They find that it really is about the “survival of the fittest” and who nature selects to thrive and produce generations far greater than the last.…

The Penascola Gulf Islands in Florida are pretty much your average definition of paradise. The area is known for the most beautiful white sand beaches and turquoise blue waters. The beach stretches for miles along the Gulf of Mexico, full of people constructing hammocks to lie in the warm sun, standing for hours fishing, and many many others jumping around the waves and surfing or swimming in the calm waters. These islands are essentially a strip of land completely surrounded by water, which means you’ll get a good view wherever you go. With many resorts, restaurants, and coastal areas, these islands have all you need.…
English naturalist, Charles Darwin, believed the finches he collected and observed on the Galapagos Islands shared a common ancestor because he found they all greatly resembled a bird located on the Ecuadorian coast off South America. When Darwin initially began his journey on the Beagle, he was biased toward the widely accepted idea that every living thing on Earth was a divine creation, which remained unchanging and existing as it was originally created. However, when Darwin arrived on the Galapagos Island he began to see a flaw in this theory. Examining and collecting the islands animal population closely and carefully he began to see uncanny similarities between the animals upon the island and the animals on the South America mainland. For example, Darwin discovered that the fossils of extinct armadillos and the currently living armadillo population on the island had many of the same features, though the current population of armadillos had certain characteristic that helped it survive in the islands environment. Using this, the finches and other animal specimens, he was struck by the idea that this animals must have migrated long ago from South America to the island, giving rise to a new and thriving animal population.…
Charles Darwin, a geologist in the United Kingdom, traveled by ship called H.M.S. Beagle around the world in five years from 1831 so that he would survey the Pacific Coast of South America. When he called at the Galápagos Island, he realized that even though in the same species, they changed their figure according to their environment for a long time. Moreover, Charles Darwin supposed that all creatures were a natural part of the evolutionary process. Galápagos iguana is a good example of this supposition. There are three types of iguanas, namely land, marine and black and white in the Galápagos Island. Now I would like to mention two differences and similarities between the three kinds of Galápagos iguana.…
You’ve heard of the islands called Maui, the Bahamas, and Ellis Island, but have you ever heard of Angel Island? Angel Island started off just like a normal island in San Francisco Bay, until the United States turned this island into an immigrate station. Both Angel Island and Ellis Island are immigrate stations, the only difference was that Ellis Island was used for the European Immigrants and Angel Island was mostly used for Asian Immigrants. Immigrants who migrated felt different emotions when they left their country to come to the United States. Angel Island is an island where Asian Immigrants began to arrive, however these immigrants changed America, and Angel Island has changed since immigrants started to arrive.…
A group of archaeologists discovered a lost island. The island was once the ancient city of Kane. It was discovered in the eastern Aegean Sea. Xenophon was a Greek historian that mentioned the island. The island is memorable because of the Battle of Arginusae in 406 B.C.…
Darwin’s theory of evolution is based on the theory of natural selection. Natural selection is the the process whereby organisms better adapted to their environment tend to survive and produce more offspring. This theory is now widely believed by many people throughout the world. Charles Darwin’s theory includes the idea that fossils of extinct animals turn up where similar animals live today. Darwin came up with this theory when he discovered fossils of animals that were very similar to the animals that were living today. Darwin also observed that the Galapagos tortoise’s had different shapes of their shells depending on which island they came from. Darwin believed that these tortoises were adapting to their environment by changing their shell…
Kurt Vonnegut’s novel Galapagos was written in 1985 and is written using addictive prose from an imaginative perspective. Like Vonnegut’s earlier work, Galapagos is characterized by exaggerated characters, imaginative scenarios, and striking insights into the human condition. And while Galapagos paints an often unflattering picture of the human species, there is great humor and affection for the characters nonetheless.…
There were many species of animals that Darwin discovered on his voyage. Two animals that Darwin studied on the Galapagos Island are the tortoise and the finch. He learned that they all had different features but they were the same species. He called this natural selection. He discovered that the animals could adapt to their environment over time, in order to survive. For example, in his research of tortoises, Darwin found that saddle-back tortoises have shells that rise in the front making it easier for them to lift their heads to eat tree cactus. While dome-shaped tortoises live where vegetation is close to the ground, making it not as important for them to be able to raise their head. He also found that finches had different kinds of beaks.…
2. Besides the finches, what two things did Darwin study while on the Galapagos Islands? He studied mockingbirds and giant tortoises…
13.4443° N, 144.7937° E are the coordinates to a 26 mile long, three mile wide island in the middle of the Pacific Ocean. Guam, is the little island I called home for four years of my life, while my mom served as a Navy Nurse. Since, then many people have asked, “Guam? Where is that? What is it like?” I could spend hours babbling on about Guam, but one word to describe Guam is, “Hafa Adai,” (hello in Chamorro, the native language of Guam). Guam is a small island with a big heart welcoming all who comes, and my family was one of the lucky guests.…
The oldest land areas of the modern Caribbean are at the extreme ends of the arc of islands in Cuba and Trinidad. The Greater Antillean islands have all had a somewhat similar geological history but they differ from one another in the distribution, form and erosion patterns of the limestones deposited during several phases of submergence and uplift through the Tertiary period and Pleistocene.…
