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

So they tried to duplicate the frogs’ swimming movements hence the first “frog stroke” was born! As time passed and mankind learned to developed new swimming techniques from these two early swimming strokes‚ the doggy paddle and the frog stroke. Now‚ the international swimming community recognizes 4 official swimming techniques‚ namely The Crawl‚ which is

Although there are differences such as the fingers are elongated and may have additional bones and the joint between upper arm and forearm is immobile‚ creating an effective paddle. Also it is said that whales have evolved from four legged‚ hairy land mammals approximately 50 million years ago. They began their transition back into the oceans by feeding on the food present in the shallows around the edge of waters. Gradually whales adapted to their marine environment

I was amazed to find out just how ancient frogs are. For 190 million years‚ the ancestors of modern frogs have roamed the earth‚ looking much the same as they do today. This means that at one time when there was a huge dinosaur eating a plant‚ there could have been some type of frog down by its feet. About 3‚800 species of frogs and toads have developed since the dinosaur days. The secret to their success is their amazing adaptability. Frogs have evolved to live in a large variety of climates.

metamorphosis of the frogs from ‘jellies specks’ He loses his innocence. This poem’s title is an extended metaphor. The naturalist in Seamus dies as he experiences the transformation from a child to a man. It’s a comparison between the metamorphosis and the transformation of the tadpoles and the child into frogs and a man respectively. Heaney’s poem ’Death of a Naturalist’ focuses on his experience of collecting and watching frogspawn as a child‚ and his reaction when the spawn turned into frogs. In the

(Gitig 2009). Organisms need to adapt both physiologically and anatomically in order to survive in changing environments. For example‚ Tibetans have developed genes to help them adapt to life at high elevation. While most humans would become very ill at such high altitudes in south-central Asia‚ the Tibetan highland people thrive in this climate. Researchers have concluded that‚ “through thousands of years of natural selection‚ those hardy inhabitants evolved 10 unique oxygen-processing genes that help
