Introduction This lesson explores the classification system used to identify animals. Learning Objectives After completing the lessons in this unit, students will be able to: Know and understand the seven levels of classification.
Apply that knowledge as they practice classifying animals. Evaluate and compare the classification of animals. Devise a classification system for the objects in their homes. Create a new species and classify it according to the principles of classification.
Preparation Print the lesson plan on a color printer. Have access to the Internet for student s. Lesson 1: Beginnings Look at the pictures of these animals, then fill in the chart below: Choose the two animals from your chart that you think are most similar and justify your choice in one sentence: Lesson 2: Organizing the animals — how it happened Back in the 18th century, a Swedish man named Carolus Linnaeus thought it was important to organize living things, and he developed a system to do just that.
Linnaeus's system has seven levels: Kingdom Phylum Class Order Family Genus Species Every animal on the planet, down to the most microscopic creature you can imagine, can be classified according to this system. K ing P hillip, c ome o ut, f or g oodness' s ake!
K ing p enguins c ongregate o n f rozen g round s ometimes. Let's look at each level and an example using one common animal. Kingdom Generally, scientists agree there are six kingdoms.
The animal kingdom called Kingdom Animalia is just one of those. Originally, Linnaeus only identified two kingdoms: Some scientists think that viruses should have their own kingdom, but currently they are not included under this system. Phylum Within the animal kingdom, the animals are divided into more than 30 phyla which is the plural of "phylum".
You might be interested in Phylum Chordata — it's the one humans and all animals with backbones are in do you see how "chordata" looks like the word "cord" — like spinal cord? Phylum Arthropoda contains insects, spiders and other animals with segmented bodies, like shrimp. Arthropods have their skeletons on the outside of their bodies think of the hard shell of a lobster and other characteristics in common.
Class The third level of classification is class. For example, Phylum Chordata has classes in it like birds, mammals Mammalia and reptiles. Order The next level, or rank, is order. Orders are smaller groups within the different classes.
Lepidoptera is the order of moths and butterflies. Carnivora is the order within Mammalia that has the most diversity in animal size.
Family The fifth rank of classification is family. When you get to this rank, people sometimes disagree about which family an animal belongs to, so you may find that different sources tell you different things. This can even happen with orders. The family for dogs is Canidae. Genus This rank looks like "genius," doesn't it?
It's the second-to-last rank, and a genus may have only one or two animals in it. If animals are in the same genus, they are really closely related. In fact, you may not be able to tell them apart just by looking at them!
When we write the name of the genus, we capitalize it and italicize it. For example, the genus of dogs and wolves, too!
Species If animals can breed together successfully, they are a species. When an animal is called by its scientific name, then that means it is being identified by its genus and species. We use a lowercase letter and italics for the species. The scientific name of dogs is Canis familiaris; however, the scientific name of wolves is Canis lupus.
Lesson 3: Using what you've learned Look back at your chart of the animals that you did in Lesson 1. Using that chart and the chart on the last page of this lesson, answer the following questions: Why do you think we left Kingdom off of the chart?
What kingdom does each of these animals belong to? Look at the class of the Chilean flamingo.
All birds belong to that class. Do you see why we call things to do with airplanes "aviation? If two animals are the same genus, then they must also be the same family, order, class, phylum and kingdom.
Why did you make that choice? Why do you think that we had to be more specific about the animals in this chart? Why can't we just put "bear"? Why did we have to say "grizzly bear? Think about the name of the kind of doctor who puts braces on people's teeth. Now think about the name of the whale suborder Odontoceti.
Do you think these are whales with teeth or whales with baleen?
The family that horses belong to, Perissodactyla, means "odd toed. Can you think of any other animals not on this chart that might belong to that family? Using the chart above, write the scientific names of the cow, the flamingo and the whale. Cow Chilean flamingo Blue whale Did you put the genus first with a capital letter?
This form of obtaining energy distinguishes them from autotrophic organisms, such as most plants, which make their own nutrients through photosynthesis and from fungi that digest their food externally. Animals may be carnivores, herbivores, omnivores, or parasites Figure Most animals reproduce sexually: The offspring pass through a series of developmental stages that establish a determined body plan, unlike plants, for example, in which the exact shape of the body is indeterminate.
Figure All animals that derive energy from food are heterotrophs. The a black bear is an omnivore, eating both plants and animals. It spends its larval stage in mosquitos and its adult stage infesting the hearts of dogs and other mammals, as shown here. A hallmark trait of animals is specialized structures that are differentiated to perform unique functions.
As multicellular organisms, most animals develop specialized cells that group together into tissues with specialized functions. A tissue is a collection of similar cells that had a common embryonic origin. There are four main types of animal tissues: Nervous tissue contains neurons, or nerve cells, which transmit nerve impulses.
Muscle tissue contracts to cause all types of body movement from locomotion of the organism to movements within the body itself. Animals also have specialized connective tissues that provide many functions, including transport and structural support.
Examples of connective tissues include blood and bone. Connective tissue is comprised of cells separated by extracellular material made of organic and inorganic materials, such as the protein and mineral deposits of bone. Epithelial tissue covers the internal and external surfaces of organs inside the animal body and the external surface of the body of the organism.
Most animals have diploid body somatic cells and a small number of haploid reproductive gamete cells produced through meiosis. Some exceptions exist: For example, in bees, wasps, and ants, the male is haploid because it develops from an unfertilized egg. Most animals undergo sexual reproduction, while many also have mechanisms of asexual reproduction. Almost all animal species are capable of reproducing sexually; for many, this is the only mode of reproduction possible. This distinguishes animals from fungi, protists, and bacteria, where asexual reproduction is common or exclusive.
During sexual reproduction, the male and female gametes of a species combine in a process called fertilization. Typically, the small, motile male sperm travels to the much larger, sessile female egg. Sperm form is diverse and includes cells with flagella or amoeboid cells to facilitate motility.
Fertilization and fusion of the gamete nuclei produce a zygote. Fertilization may be internal, especially in land animals, or external, as is common in many aquatic species. After fertilization, a developmental sequence ensues as cells divide and differentiate. Many of the events in development are shared in groups of related animal species, and these events are one of the main ways scientists classify high-level groups of animals.
During development, animal cells specialize and form tissues, determining their future morphology and physiology. In many animals, such as mammals, the young resemble the adult. Other animals, such as some insects and amphibians, undergo complete metamorphosis in which individuals enter one or more larval stages.
For these animals, the young and the adult have different diets and sometimes habitats.
In other species, a process of incomplete metamorphosis occurs in which the young somewhat resemble the adults and go through a series of stages separated by molts shedding of the skin until they reach the final adult form. Asexual reproduction, unlike sexual reproduction, produces offspring genetically identical to each other and to the parent.
