Identify the organism in the table that is least closely related to the others 2. Use the information in the table to coretruxt a cladogram of these animals below. CladogramWRITTEN WORK Q4-17.1.1 WRITTEN WORK TITLE: Cladistic System & Phylogenetics Worksheet WRITTEN TASK OBJECTIVE: To describe the concepts learned about cladistic system and phylogenetics Instruction: Read the passage carefully to complete the table and diagram. CLADOGRAM ANALYSIS What is a cladogram? It is a diagram that depicts evolutionary relationships among groups. It is based on PHYLOGENY, which is the study of evolutionary relationships. Sometimes a cladogram is called a phylogenetic tree (though technically, there are minor differences between the two). In the past, biologists would group organisms based solely on their physical appearance. Today, with the advances in genetics and biochemistry, biologists can look more closely at individuals to discover their pattern of evolution, and group them accordingly - this strategy is called EVOLUTIONARY CLASSIFICATION CLADISTICS is form of analysis that looks at features of organisms that are considered "innovations", or newer features…Name To be Submitted on: Time Frame: EVOLUTION At the end of this lesson, you will be able to describe general features of the history of life on Earth, including generally accepted dates and sequence of the geologic time scale and characteristics of major groups of organisms present during these time periods; and explain the mechanisms that produce change in populations from generation to generation (e.g., artificial selection, natural selection, genetic drift, mutation, recombination) TOPIC: Learning Competencies: Earth formed 4.6 billion years ago. Life first appeared on Earth about 4 billion years ago. The first life forms were microscopic, single-celled organisms. From these simple beginnings, evolution gradually produced the vast diversity of life today. In this lesson, you'll learn about the history of life from its origins until now. You'll learn that living things had to cope with some astounding changes. Giant meteorites struck Earth's surface. Continents drifted and…

How does embryology provide evidence for evolution? 3. How do homologous and vestigial structures provide evidence for evolution? 4. What could be possible for some species belonging to the same family to be presently living in various locations on Earth? You can furthel support your answer with an example.please reflect on the three major subject areas 1. Evolution - including evolutionary processes, speciation, the fossil record, and phylogenetics. 2. Biodiversity - including the diversity of microbes, fungi, plants, and animals. 3. Ecology - including organismal ecology, population ecology, community ecology, ecosystem ecology, and conservation ecology. For each of the subject areas, describe at least two ways that concepts involved with that subject area relate to aspects of everyday life, the medical field, or hobbies.PERFORMANCE TASK: 1. Go online. Choose a group of organisms you are interested to work with (e.g. invertebrates); 2. In tabular form, list all the characters. Evaluate the characters (whether primitive or derived). 3. Remember that in building your cladogram, use only shared derived characters. 4. Construct your own cladogram.
