The title of the article I was assigned to read in Marine Biology was called “This is your ancestor” by Jack Monoclinic and Richard Barnes, published in November 2004. This article is about tracing evolution in terms of seas sponges. A micro biologist named, Mitchell Songs was tracing the DNA chain of animals to find the very first species that rooted off into all other animals including humans.
“When micro biologist Mitchell Songs decided to trace human evolution to its roots, he had no idea he might find sponges” (Page 1 . . Genes research was based on the findings of Carl Whose, who had the same idea in 1977 but had insufficient technology to prove his findings. Songs decided to go even further into the DNA ribbon.
After more than a year of research, comparing the DNA of thousands of animals, including humans, Songs found a key link between human and sea sponge DNA that appeared to match one another. This finding was revolutionary as no one has ever gotten so far in this type of evolutionary research. Sponges are very unique creatures.They have no organs, no veins, and no nerve endings as other creatures do. Sponges appear to merely sit on the ocean floor while sea water passes in and out of them.
After Songs made his initial discovery, he decided to more closely examine the sea sponge itself. One way he did this was to place a sea sponge In a Jar and monitor It for 48 hours. Over the 48 hours he observed that the sponge actually moves on its own, very very slowly. He did this experiment several times and noticed that the sponge would climb up the wall of the Jar.In order to determine how the sponge moves, he dissected one and realized that the sponge has thousands of cells with tall like flagella that enable t to move itself along the sea bottom and push food through Its pores.
There were still holes in Genes research In terms of linking human evolution to sponges. After continuing his research for some time, he was getting desperate to prove his findings and moved on to plants and fungi which Is where he made another very big discovery. Fungi. Fungi seemed to be the link he was hoping to find.It has one strand of DNA that was present In all other DNA strands of animals and humans.
Until this discovery fungi was thought to be neither plant, nor animal. These findings changed hat thought. Because of his research, he redefined the theory of evolution. Fungi DNA appears to be the link between sea sponges and all other living animals Including humans. From this article I learned three things which I found to be quite Interesting. It was Interesting to me to find out that sponges actually have the ability to move on their own, although quite slowly.Also Interesting to learn was how the fungi strand of DNA matches all others and that we now have the technology to match DNA strands wealth a year where In the past this would have been nearly Impossible.
The title this article ‘This Is your ancestor” peaked my Interest In the article right away because of the picture of sea sponges below the title, so I was anxious enough to read the article to see what It could tell me about sea sponges and If It was possible that humans actually evolved from them.This article was Informative and did not leave me with any further questions and I would recommend It to others Interested In flung out more about different evolution theories.
