Scientists have been fascinated about human sleeping cycle, where the darkness of sunlight triggers a chain of molecular event spreading from our eyes to our pineal gland thus generates a hormone melatonin into the brain. With the melatonin, it alters the electrical rhythm and brings brain to realm of sleep. During this new study, scientists discovered this power sleeping cycle occurred 700 million years ago. Moreover, through this study, the author proposes that our sleeping habits evolved from the rise and fall of our tiny ocean ancestors- Platynereis dumerilii. These marine worms spend most of the nights near the ocean surface, feeding on algae or other resource; however, during day time, they sunk to the bottom where they can hide from

However, if this study was to take further study on the human sleeping habit, there might raise more measurement validity. Such as people might tell researcher what they want to hear or even there might be missing data. Thus a careful planned and conduct research is critical to any social/science research. I personally enjoy reading this article for three main reasons. First, the context was clear. The structure layout was well organized and neatly presented that all information was given clearly. I knew what the hypothesis, the research method, and most the conclusion were. Second, the definition was explained. I faced difficulty when reading a scientific research because I cannot understand the term or languages. It is important to communicate directly with your audience when writing a social research paper, because you want to your audience to understand it. Third, it did not manipulate audiences’ trend of thoughts. Some news article leaves no space for the audience to think about the topic. However, this new articles brought the critiques of the study and how it may be improved. There is no perfection to one research. There will also be errors; however, we can limit it by replication and interitem reliability, meaning to conduct a research using different
