Week11a+Speciation+Summary

No problems here, as expected. Some like to quote the entire title, such as "promiscuous orchids', instead of simply 'orchids', but that's about it.
 * Question 1: What is your team number? Which is the organism you are assigned to work on?**

**Question 2: Which methods are described in the article (exmaples: DNA analysis, behavioral analysis, counting patterns on the skin etc.)?** LOTS of trouible here. The most common was the description of the speciation process, or 'method' instead of the method that the researchers used in their study. Now, granted, it is not always so clear form the article what they were doing. Were they comparing appearnaces, traits in general, DNA sequences between groups? Some wrote "behavioral analysis", but that doesn't give me or anyone any idea what that means. What type of behavior? What were the researchers doing while they were observing? Were they visible to the animals or not?

This will be come important in the project you guys have hopefully started. You can just say "behavioral analysis' and expect it to be clear. Here is one example I really liked: [|Per2AshleyTojong] wrote: "The method that was used in the article was behavioral analysis. The scientists studied the greenish warblers singing and compared the songs to the birds closer to central Asia. Once they saw the difference in the songs, they realized the ring has been broken between the species." This is a good example of making things simple and therefore showing the writer's own understanding: Ashlet wrote "behavioral analysis", but continued to elaborate on that entailed. I highly recommend this post as a model to follow in your project.

**Question** 3a, 3b: **3a: What was thought to be the initial reason why the original species separated into two or more groups?** **3b: What needs to happen in order for an initial separation to end up giving rise to new species?** **(If you are not sure - go over the powerpoint on speciation!!)**

"I believe what needs to happen in order for a complete new species is that the electirc fish has to mate with a whole different type of fish, or fish from different waveforms." "maybe having them both lay eggs in the same area at the same time could cause a new species"
 * In 3b several answers looked like this. But GUYS and GIRLS - inter-species mating does not exist!!! Have you ever opened my powerpoint?!**

Taek a look at [|Per6RosaR]'s post: "3B. In order for an initial seperation to happen between a certain species, the Tropical fish would have to be divided into 2 or more groups __for a long time__ because of a variety of factors lic physical barriers. Even though they have the ability of mating they dont because they are far apart from each other. __Due to the seperation there is no gene flow between them so little by little they start loosing the ability to mate with each other. After decades of seperation, when they come together, they have no ability to mate with each other due to the lack of gene flow__."

Although decades is an underestimate if we are talking about vertebrates..
