Hypothetical Phylogenetic Tree: Using a cladistic approach‚ we constructed a hypothetical phylogenetic tree of many different plant taxa by comparing their morphologies. We first decided to sort the various types of plants into groups based on morphological features. After sorting these plants into five different groups we began to determine how the plants differed from eachother in the group and what features set them apart. From this we started to create the hypothetical tree and decided

16.1 All of Life is connected through its Evolutionary history Phylogeny- is the history of descent of organisms from their common ancestor. Groups of evolutionarily related species are represented as related branches in a PHYLOGENETIC TREE. - A group of species that consists of a common ancestor and all its evolutionary descendants is called a CLADE. Named clades and species are called TAXA. - HOMOLOGIES are similar traits that have been inherited from a common ancestor. - A trait that is

Evolution: descent with modification; the idea that living species are descendants of ancestral species that were different from the present-day ones. Biology: the scientific study of life. Emergent properties: new properties that emerge with each step upward in the hierarchy of life‚ owing to the arrangement and interaction of parts as complexity increases. Systems biology: an approach to studying biology that aims to model the dynamic behavior of whole biological systems based on a study of the

Introduction Cladogram is a tree diagram that is designed to determine the relatedness and evolution of species. Two methods to produce a cladorgam one based on morphological characteristic and another based on sequence of amino acid. Based on morphological characteristic‚ first‚

different numbers of shared derived characters exist between different groups‚ we can draw a diagram of branching lines which connect those groups‚ showing their different degrees of relationship. These diagrams look like trees and are called "phylogenetic trees" or "cladograms" (CLAY-doe-grams); see examples provided by your teacher. The organisms are at the tips of the stems. The shared derived features of the homologous structures are shown on the cladogram by solid square boxes along the branches

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

He was surrounded by acquaintances beneath his social class‚ relatives‚ and servants.[2] He was described as a youth who “searched for parental love” and a “place in a society with rigid class structures”. He was also the grandson of the landlord protagonized by José in the novel Po-on. In Tree‚ the boy narrated
