descendants. Paraphyletic- An evolutionary unit that includes an ancestral population and some‚ but not all of its descendants. They are not meaningful units in evolution. Polytomy- Term for internal node that has more than 2 descendants (sister taxa) Homoplasy- Similarity among organisms of different species due to convergent evolution. Compare with homology. Example: Bird wings versus Bat wings. Both different ancestor‚ but both have wings.

February 19‚ 2013 In 1925 John Scopes challenged the Tennessee school system and the law when he decided to continue to teach Darwin’s theory of evolution although it had been banned to teach since it had went against thing written in the bible. This drew the attention of two men Clarence Darrow and William Jennings. Jennings stated that the theory of evolution isn’t fact and made students doubt their Christian faith while Darrow argued that the children should have intellectual and religious freedom

The theory of evolution through natural selection describes how humans and other animals have evolved over a long period of time. Charles Darwin made a hypothesis based on the different pictures of the same animal that were found over the years. There was a slight change in its features‚ which brought him to the conclusion of how animals adapt over time. His theory began to gather more evidence when discovering fossilized “ape-like” bone structures‚ which gives great data to his theory that all animals

Bacterial Evolution Outline Evolution is defined as the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth. The theory generates from Darwin’s Theory Of Evolution. Darwin’s Theory Of Evolution describes a process in which all life is related and has came from a common ancestor. More complex creatures evolve from less complex or simple ancestors over time due to genetic mutations that are deemed beneficial

Herbert Spencer is popularly known for his treatment of evolution. The evolutionary doctrine was no doubt the foundation of Spencer ’s sociological theory. He‚ however‚ presented the organic analogy‚ a secondary doctrine which also played a vital role in his thought system. He identified society with a biological organism. (Agarwal) One of the main reasons that Herbert Spencer was important to sociology was because of his views and ideas about evolution. Charles Darwin is always given credit for the idea

discussion board and you should look at other web sources to add to your posts. PBS ran a NOVA video this last summer entitled "What Darwin Never Knew". You can find that video at http://www.pbs.org/wgbh/nova/evolution/darwin-never-knew.html . This web page has lots of information that explains evolution theory and it is a good addition to this NC Live video in developing an understanding of how genes adapt to change through time.

selective breeding to make our daily life easier. We use it in food products‚ we use it in humans which is also known as eugenics but we do it especially in animals. Charles Darwin also known as the father of evolution used selective breeding to help gather proof for his schedueled system for how evolution works by experimenting with animals such as birds. This topic has gotten alot of contreversy as it is considered as unethical action done by us humans. Selective breeding is a form of selection in which
