selection was a process in which “tiny variations were selected by virtue of whether or not they helped organism survive” (Wyhe‚ 2016). In Darwin’s voyage to the Galapagos islands‚ he discovered finches with different beak size that still somewhat resembled one another. Adaptive radiation was used to describe this concept because the finches all came from one common ancestor but developed variation based on the environment and food supply available. Birds that were generalist survived on variety of

depending on the habitat‚ those with advantageous attributes would survive and those without would die off. “Darwin had collected 13 similar but separate species of finches. Each finch species had a distinctive bill specialized for a particular food source.[…]The similarities of the Galapagos finches led Darwin to infer that the finches shared a common ancestor.” (Darwin’s Theory of Evolution) Those without a special bill to easily collect food would be not be selected by nature to continue their

Math Darwin‚ again‚ is very famous‚ or infamous‚ for his studies on finches. First he noted on the differences on the sizes of the birds. Their size accounts for certain elements that occur in nature. For instance‚ concerning islands (and how effective of an example they are) they have different habitats to live in. Certain islands have bigger predators‚ others have smaller or no predators at all. In island 1 the finch lives with the more predators‚ and therefore could grow larger than the predators

conditions. This applies to all living organisms on the planet. Adapting and being able to change is what keeps a species from going extinct. Darwin proved this theory by doing experiments on finches on the Galapagos Island. He observed how finches would react to any challenge that were thrown their way. Some finches went extinct due to them not being able to keep up with the number of predators and decrease in the type of insects that they consumed. An example of natural selection is penguins. Penguins

Christianity is consisted of many beliefs‚ and topics which leads to debates‚ agreements‚ disagreements‚ and heated discussed. While some Christians don’t share the same belief‚ the majority of them believe this: Jesus died for our sins‚ he was then buried and resurrected‚ and he now offers salvation to people who receive him in faith. But back to different beliefs‚ there is two theories created by one man that has been debated about for years. That man is Charles Darwin‚ a British born naturalist

These four main theories were developed to explain how we as humans behave‚ think and react. Although the human mind still remains a mystery

Every organism’s difference is a variation. While I traveled to the Galapagos‚ I noticed many variations in the finch species. From island to island‚ each finch bird has a different type of beak. I hypothesize this is because each island has different food sources so each bird adapted to their environment. Some have sharp
