writing assignment 612
In simplest terms, evolution can be defined as a change in allele frequency over time. A fact of nature is that allele frequencies for any given gene are always in a state of flux and for that reason evolution is a fact of nature. At the same time we have evolutionary theories that help us explain why allele frequencies change in the first place. For this section we will explore these evolutionary mechanisms.
The purpose of this discussion board is meant for you to share an article or a news story that specifically deals with how evolutionary mechanisms are shaping nature around us. Look for a story in the news that specifically deals with only one of the following — natural selection, gene flow, genetic drift, or sexual selection.
Your job will be to do the following:
- Give a short summary of what you read.
- State the evolutionary mechanism involved and explain how that evolutionary mechanism works.
- Lastly, give a short explanation of what is promoting the evolutionary change in the first place.
- Make sure you cite your work so that others can follow the news article.
