Lesson Overview Lesson Overview Finding Order in Diversity History of Life Project Goals and Grading: You will work with your partner sitting at your table to create a summary of the major event that you will be assigned. You will create an information poster using 1 PowerPoint slide Your poster (1 PowerPoint slide) must include: A title that is large and visible and describes the event. Underneath the title, write the estimate of how long ago the event occurred. (20 points) At least 1 or 2 pictures that represent the event. (20 points) A description of what occurred during the event. (50 points) You will present the event to the class and hang it on the timeline. (10 points) Timeline: You will have the rest of today and tomorrow to complete your poster. We will present and create the timeline on Tuesday.

Lesson Overview Lesson Overview Finding Order in Diversity Basic Characteristics of Animals 1.Animals exhibit all of the characteristics of living things. 2.Animals are all heterotrophs- they obtain nutrients and energy by eating other organisms. 3.Animals are also multicellular- their bodies are composed of many cells. 4.The cells that make up animal bodies are eukaryotic- containing a nucleus and membrane-bound organelles. 5.Unlike the cells of algae, fungi, and plants, animal cells lack cell walls.

Lesson Overview Lesson Overview Finding Order in Diversity Directions: Write and Answer the following questions under our notes in the Life History tab under The Tree of Life. 1.Do you notice any patterns in the timeline about the history of animals? 2.What is the most interesting thing to you after looking at the timeline? 3.When did animals evolve the ability to live on land? 4.How many years did it take for the first living things to evolve from the formation of the earth? 5.How long did it take between first life and the first animals that evolved?

Lesson Overview Lesson Overview Finding Order in Diversity Classification Goals 1.Helps organize the millions of living species into groups that can be studied more easily 2.Shows relationships between organisms 3.The system can be used universally around the world and eliminates the confusion of common animal names

Lesson Overview Lesson Overview Finding Order in Diversity Binomial Nomenclature Carolus Linnaeus developed this two-word naming system in the 1730s. Rules 1.The scientific name usually is Latin. 2.It is written in italics. 3.The first word begins with a capital letter, and the second word is lowercase.

Lesson Overview Lesson Overview Finding Order in Diversity Taxonomy Linnaeus also developed a classification system that organized species into larger groups. Traditionally, organisms were grouped together by anatomical similarities and differences. Today, DNA and RNA sequences and evolutionary relationships are used to show similarities and differences between organisms.
