Evolutionary lineages

An evolutionary lineage is a series of populations of organisms that descend from a common ancestor. Each species in the lineage is the direct consequence of evolutionary change from a common ancestor. A phylogenetic tree is generally used to display lineages visually. Lineages are components of the phylogenetic tree of life. Molecular systematics procedures are widely used to predict lineages.

10. Taxonomy versus Phylogenetics For novice biologists, taxonomy and phylogenetics are difficult concepts to understand and keep separate. This confusion is made worse because modern taxonomic methods make use of molecular tools. Write an essay that contrasts taxonomy to phylogenetics and explain how both disciplines are important to our understanding of species and evolution. Your essay should include a description of taxonomy and phylogenetics, as well as a detailed explanation about how information is represented in a phylogenetic tree or a cladogram. It may help you to frame your argument if you start by constructing a paragraph for yourself that says: "Before reading my paper, my reader will think X. After reading my paper, my reader will think y."
Which statement about the taxonomic classification system is correct? There are more domains than kingdoms Kingdoms are the top category of classification Classes are divisions of orders Subspecies are the most specific category of classification.
To construct a phylogenetic tree by applying the principles of parsimony to molecular sequence data, one would: a. start by making assumptions about variations in the rates atwhich different DNA segments evolve. b. group together organisms that share the largest number ofancestral sequences. c. group together organisms that share derived sequences, matching the groups to those defined by morphologicalcharacters. d. group together organisms that share derived sequences, minimizing the number of hypothesized evolutionarychanges. e. identify derived sequences by studying the embryology of theorganisms.

Please create a phylogenetic (evolutionary) tree given this criteria and follow all points! There are three domains of life - Bacteria, Archaea, and Eukarya. Start by drawing these three main branches. Then add branches for plants, animals, fungi, and protists. When adding all these branches, don't just add them randomly. The branching pattern reflects evolutionary relationships. You should use the relationships/branching patterns. Then add additional branches for • three species of bacteria • three species of archaea three species of plants three species of animals • three species of fungi • three species of protists (single-celled eukaryotes) You can pick any species you want. For each species, be sure to add 1 synapomorphy (shared derived character) that defines the species or group. • Finally, label the tree with all the terms (parts of a tree, not phylogenetic groups) when describing a phylogenetic tree.
Draw a simple phylogenetic tree for two sisters clades with a common ancestor. Each sister clade consists of two taxa. Define the following terms and use to label your diagram: clade, node, branch, common ancestor, and taxon.
Which of the following is FALSE regarding phylogenetic trees? 1) The branch lengths on the tree are scaled to molecular (DNA) changes and/or time. 2)Phylogenetic trees have shown us that there is much more bacterial diversity compared to eukaryotes. 3) Phylogenetic trees show the evolutionary relatedness of different organisms. 4). The branch lengths on the tree depict abiotic and biotic factors affecting speciation.
