Summary:
Boris Vinatzer is a professor at Virginia Tech proposed a new way to classify organisms. His new method is based on the genome sequence. This method is based on the Linnaeus Classification System that was used by scientists. He doesn't want to change the entire classification system but wants to add more specific classifying data. He believes that the genetic system will allow for an easier system.
Connection:
This is article is relevant to our curriculum because we learned about the classification system. We also learned about Linnaeus Classification System. The new genetic classification could change some of the things that we learned about. Some organisms could be placed in a different kingdom if they are more closely related based on the new genome sequence.

Exactly how would organisms be classified "based on their genome sequence?" Would the scientists only use one set of genes, like mitochondrial dna to compare, or would they devise an algorithm to account for all the genes? If so, what would define an orginism as an "animal," if we are solely looking at DNA?
ReplyDeleteThe article didn't state the type of DNA they will use specifically. But scientists wouldn't solely look at DNA in order to classify. Boris Vinatzer wants to use DNA to help classify animals more specifically. They will still use the current classification system but he is proposing that using DNA will help
ReplyDeleteHow will the genetic system help classification of organisms?
