Running head: EVOLVING DOLPHINS The Evolution of Dolphins JD Biology 101 January 16‚ 2011 Professor: Abstract Dolphins are a fun and playful species. They have evolved to be well suited for their aquatic environments. Over many years these animals have gone from land dwellers to deep-sea divers. These amazing creatures are considered one of the top predators in the marine ecology system. The Evolution of Dolphins Imagine you are at Six Flags Discovery Kingdom swimming with the

This evolution that happens in response to the changes in the biotic factors of the ecosystem is called co-evolution. The habits or changes in one organism in an ecological relationship create a pressure that drives changes to another. Therefore‚ evolutionary changes in organisms due to changes in temperature‚ water and other abiotic factors are not co-evolution‚ even if changes happen simultaneously in organisms that are in a specific ecological relationship. Easily observable co-evolution occurs

similar in two or more species but not present in their common ancestor are said to be analogous. Analogous features arise through convergent evolution as they have developed separatley in unrelated taxonomic groups as a result of a similar way of life‚ for example the wings of birds and insects as they do not share a common ancestor with wings. The theory of evolution suggests we would expect a higher number of shared homolgies for closely related species‚ and decreasing number as the species become less

The 1920’s was one of the most controversial time periods in all of American history. With many advances in science came new theories such as Charles Darwin’s theory of evolution. With the theory of evolution being incorporated in schools many religious families became severely distressed. Court cases began popping up all over the nation in both favor and opposition towards the new teaching of how life on earth began. The most famous trial being the Scopes trial‚ which effected the education system

Evolution is the theory that every single living structure originated from old progenitors. Through a progression of mutations‚ genetic float‚ movement‚ and natural selection today’s relatives demonstrate an astounding measure of likenesses and assorted qualities. Evolution on a little scale is called microevolution‚ identifying with the progressions that happen‚ for example‚ creepy crawlies getting to be impervious to pesticides. Macroevolution alludes to the fantastic scale. It is connected with

Natural selection is about slow but steady progress. Through it‚ populations constantly get better-adapted. When this process is completed for all populations‚ evolution will come to a stop. 2.

Gradualism versus Punctuationism Although modern evolutionists are thought to be divided on the issues surrounding evolutionary theory‚ a close look at the evidence suggests that both the gradualist school of thought and the punctuationist school of thought share many characteristics in common. This is especially true when evaluating their beliefs about the fossil record‚ disagreement with the theory of saltation‚ and the misinterpretation of the word "rapid" in terms of punctuationist theory
