Evoblog 11 Weblab Phylogeny

There are three groups in phylogenetics-- Eukaryota, Archae, and Bacteria. The Eukaryota consist of humans and animals, organisms that contain a nucleus, the Archae are single-celled organisms, and the Bacteria group consist of single-celled organisms that are everywhere and has lived for very long. All life is related and can be traced back through lineages to a common ancestor. Family resemblances or features are passed on from generation to generation.A genealogy shows how the lineage of parentage and a common ancestor among them all.From this lab I learned that parrots and caimans are very similar because they are all vertebrates. A common ancestor refers to the most recent common ancestor of any two (or more) organisms.Also cladograms represent the common ancestors where their relationships are based on shared features that have been inherited from a common ancestor. From this whole lab interactive i learned that life is very diverse and yet all living things are related. Also that branching diagrams like claodgrams show how how living things are related to one another and is able to find even older species along the diagram. I would give this tutorial a rate of 9 out of 10 because of the well information but lack of clear examples and ideas to visualize.
