    In an attempt to find a correct phylogenetic tree, our group has found that Phylogenetic tree C shows a significant lineage. After researching, Phylogenetic Tree C seems to be an accurate depiction of hominid evolution. It shows a clear line of lineage that begins with the common ancestor A. Afarensis. To explain how the hominids connected in the lineage, our group decided to compare the skulls’ cranium width and length of braincase. We concluded that over millions of years, the width of the cranium

  • The Butterfly Effect: The Phylogenetic Tree

    742 Words  | 3 Pages

    how exactly did the butterfly get those wings? Scientists have recently formulated a complete phylogenetic tree that showcases more than 200 species of butterflies and their evolutionary history and relation to other butterflies. It is because of this completed evolutionary chart that scientists are now able to trace back when and how the butterflies we see today are what they are. A phylogenetic tree is a scientific blueprint that allows someone to look back at a particular species past and locate

  • Arthropods are the Major Component in Animal Diversity

    morphogenisis, therefore it could awnser many questions regarding evolutionary biology (Regier & Shultz, 1997). To awnser those questions is required a a phylogenetic framework. Unfortunally evolutionary relationships among the majorority of arthropods groups are still controversial (Regier & Shultz, 1997). One of the problems of phylogenetic reconstruction of arthropods is the choice of a outgroup (Giribet & Ribera, 1997). Acording to Giribet & Ribera (1997) an outgrup must be historically related

  • The Phylogenic Tree

    Phylogenic Tree Name Institution Name The phylogenetic tree is also known as the evolutionary tree. As the name suggests, it represents the relationship of evolution in different animal species of animal that are represented in a tree-like diagram or branching diagram. The taxa that are drawn into diagram are according to their differences and similarities in their genetic and physical materials. The animal that is seen today is at the tip of the tree is the modern animal. The tree is often branched

  • Ancient Penguin Discoveries and Evolution Essay

    1207 Words  | 5 Pages

    Ancient Penguin Discoveries and Evolution In a recent BBC News article, Ivan Noble discusses the possibility that ancient penguins may hold the key to unlocking the mysteries behind the complicated molecular clock of evolution. Although a seemingly unlikely animal to research, prehistoric penguin remains in the Antarctic often have been the basis for study, research, as well as debate in the modern science world. Because the prehistoric relatives of the cute and cuddly modern day

    Fish phylogenetic tree based on protein size Amanda Reed Lab partners: Lecia Redwine, Kyle Hatcher TA: Baneshwar Singh Biology 117, Section 25 Tuesday 10:30 AM Introduction       Although tree diagrams have been used since the days of Charles Darwin, biologists have only recently adopted the tree model of evolution to read and interpret phylogenies. One of the reasons for this is the confusion that often arises from using a tree model to describe a phylogeny (Baum, 2008a). Many people interpret

    . As you can see replicators played a huge part in creating life. How did replicators lead to the first cell though? If replicators are meant to replicate and reproduce how did they end up making a living organism? The first cell is presumed to have arisen by the enclosure of self-replicating RNA in a membrane composed of phospholipids which are the principal components of cell membranes. The process of replication lead to the first cell which is called LUCA (Last Universal Common Ancestor). Many

  • Evolution Of The Endemic South American Animals

    thought to be true, he is trying to determine a phylogenetic tree using collagen found in fossils of extinct ancestors of South American mammals. The study required the use of fossil records and the molecular phylogeny. The author isolated proteins found in the collagen of the ancient remains of these creatures and sequenced it. The author then observed the structure using liquid chromatography (tandem mass spectrometry). As a result, a phylogenetic tree was created with many creatures linked based

    1. Did the construction of the phylogenetic tree based on the 14 living Caminalcules change the way you would group Caminalcules species in your taxonomic classification (chart)? What does this suggest about classification based on strictly of similarity versus evolutionary relationship? The phylogenetic tree was more of an evolutionary tree. It showed the evolution of the organisms and their ancestors or traits that they branched off of. The chart however just simply organizes and separates the

  • Essay On Cetaceans

    the medical aspects and applications of mammalian genetics, such as specific types of cancer genetics or stem cell differentiation, my topic will discuss perhaps the not as applicable, but by no means less interesting radiation, biodiversity, and phylogenetic relationships among cetaceans. This topic is of major interest to me because of my fascination with the origin and evolution of life on earth. When I was younger I had an ambition to become a paleontologist and study prehistoric life, particularly
