Galapagos Islands



Tuesday, April 29, 2008 Caitlyn Cronin The Galapagos Islands had a resouandig impact on the formations of darwins thoery of natural selection.

Weather
Although located on the Equator, the [|Humboldt Current] brings cold water to the islands, causing frequent drizzles during most of the year. The weather is periodically influenced by the [|El Niño] phenomenon which brings warmer temperatures and heavy rains. During the season known as the "Garua" (June to November) the temperature by the sea is 22°C, a steady and cold wind blows from South and Southeast, and frequent drizzles (Garuas) last most of the day, along with dense fog which conceals the islands. During the warm season (December to May) the average sea and air temperature rises to 25°C, there is no wind at all, there are sporadic though strong rains and the sun shines. Weather changes as altitude increases in the large islands. Temperature decreases gradually with altitude, while precipitation increases due to the condensation of moisture in clouds on the slopes. There is a large variation in precipitation from one place to another, not only with altitude but also depending on the location of the islands, and also with the seasons. The following table corresponding to the wet 1969 shows the variation of precipitation in different places of Santa Cruz Island:

Studies of certain molecules essential for life also provide strong evidence for evolution. Cytochrome C is a protein that helps organisms produce energy. Biologists have been able to determine the sequence of building blocks — called amino acids — that make up this protein. When they compare the 104-amino-acid sequence in human Cytochrome C to that in other species, they find that it is identical to the sequence in chimpanzees, 1 amino acid different from rhesus monkeys, 10 amino acids different from whales, and 35 amino acids different from wheat.

**Ecuador Weather and Climate**
Due to geographic differences in altitude, longitude and latitude, and the climatic effects of the Pacific Ocean, the Amazon, and the Andes, the various regions and sub regions of Ecuador have very different climates and microclimates. The Pacific coast has a rainy season between December and May and a dry one from June to November. The temperature oscillates between 23 and 26 degrees centigrade. The Highlands, on the other hand, has a rainy, cold climate from November to April and a dry one from May to October. The temperature here is between 13 and 18 degrees centigrade. In the Amazon, the climate is rainy and humid between January and September, with temperatures between 23 and 36 degrees centigrade, and it is dry between October and December. The Galapagos has a temperate climate with temperatures ranging between 22 and
