What is Mitchondria RNA? Where are we from?

Like every other human, I came from Africa ultimately. But anthropologists have long known that early humans branched off as they left Africa and spread throughout the world. My particular lineage takes my ancestors out of Africa and through the Middle East. At this point, roughly 40,000 years ago several groups split off – one going south into India and eventually making its way to Australia, while another ends up in China.

During the scientific inqury class, I have had a chance to think where I am from with scientific evidences. I believe that I have strong faith to God. So, first time, when Dr, Rood tried to lead us to think about Mitchodria Eve, I felt akward. Also, he mentioned about Ameoba with Bacteria, I was really curious how to solve or tell about the theory.
So far, so Good. I mean, I like that he keeps giving a chance to think about the topic. According to the bible, Gen1:1, God creates the world.
I belive Christians specially, young students should know that clearly also with scientific thinking.

Deductive reasoning

In logic, we often refer to the two broad methods of reasoning as the deductive and inductive approaches.

Deductive reasoning works from the more general to the more specific. Sometimes this is informally called a "top-down" approach. We might begin with thinking up a theory about our topic of interest. We then narrow that down into more specific hypotheses that we can test. We narrow down even further when we collect observations to address the hypotheses. This ultimately leads us to be able to test the hypotheses with specific data -- a confirmation (or not) of our original theories.

Induction reasoning

Inductive reasoning works the other way, moving from specific observations to broader generalizations and theories. Informally, we sometimes call this a "bottom up" approach (please note that it's "bottom up" and not "bottoms up" which is the kind of thing the bartender says to customers when he's trying to close for the night!). In inductive reasoning, we begin with specific observations and measures, begin to detect patterns and regularities, formulate some tentative hypotheses that we can explore, and finally end up developing some general conclusions or theories.

These two methods of reasoning have a very different "feel" to them when you're conducting research. Inductive reasoning, by its very nature, is more open-ended and exploratory, especially at the beginning. Deductive reasoning is more narrow in nature and is concerned with testing or confirming hypotheses. Even though a particular study may look like it's purely deductive (e.g., an experiment designed to test the hypothesized effects of some treatment on some outcome), most social research involves both inductive and deductive reasoning processes at some time in the project. In fact, it doesn't take a rocket scientist to see that we could assemble the two graphs above into a single circular one that continually cycles from theories down to observations and back up again to theories. Even in the most constrained experiment, the researchers may observe patterns in the data that lead them to develop new theories.

These drawings were very difficult but I enjoy this class very much!!!
