Which of the following traits is shared by all vertebrates at least in some developmental stages except the lampreys notochord vertebrae cartilaginous skeleton cranium head mouth with jaws. Introductory Video. Objective: Students will identify vertebrates and classify some as birds and fish.. Lesson 2.1 God's Design of Vertebrates. Unique. One of a kind. Verterbrate: An animal with a backbone. PHYLUM: CHORDATA. SUBPHYLUM: VERTEBRATA. VERTEBRATES. ANIMALS WITH:. Dorsal nerve cord. Hollow backbone. Ventral heart . 5 major classes . Classified by:. Skin covering. Heart chambers. Reproduction. Embryological Evidence for Evolution. Development Videos & Articles. Main idea behind our activity was to determine how the similarities between the embryos of vertebrates provides evidence of evolution . Learning Objectives : To explain how animals are classified into groups.. Key Words: . How do we identify living from non living?. There are seven essential life processes..  . To remember these processes meet . By: Haya Al . Rabban. What are Vertebrates?. Vertebrates are animals that have backbones like Fish, Amphibians, Reptiles, Birds and Mammals . Fish. Fish have slimy bony scales for protection and . They also have gills for breathing. They get thousands of eggs and they don’t worry about the eggs.. Invertebrates. I can classify animals by determining if. they are vertebrates or invertebrates.. Essential Questions. • . Why do we classify animals. ?. • How do we classify animals?. Think-Pair-Share. Regulates water, pH and ion balance . Kidneys present in all vertebrates, but exchanges can occur at gills, skin, liver, and specialized salt glands. . Urinary system. Development is again used for comparisons among our different vertebrates. Cnidaria. Ctenophora. Rotifera. Nematoda. Nemertea. Mollusca. Annelida. Arthropoda. Bryozoa. Phoronida. Brachiopoda. Echinodermata. Chordata. No true tissues. radial symmetry. diploblastic. true tissues. - Reptiles and Mammals -. Amniote. Egg. Amnionic sac – protects embryo. Allantois – disposal sac for embryonic waste, works with chorion in gas exchange. Yolk sac – storage and transfer of nutrients to developing embryo. The . Protochordates. as Ancestors. Some living chordate groups may resemble the primitive vertebrate ancestors (. protochordates. ). Hemichordates. Burrows in marine sediments (acorn worms). (+) pharyngeal gill slits; . Objective. :. . To compare the anatomy of a frog with that of the human body. Bell work: . Complete a Venn Diagram that details the similarities and differences between frogs and . Homo sapiens. :. The Diversity of Life. Taxonomy . is the study and practice of classifying living organisms.. Modern taxonomy uses the three domain system.. Domain . Archaea. : . Unicellular and live in harsh environments; no nuclei. Introduction. To survive in a changing world vertebrates must detect changes in their external and internal environments and make appropriate behavioral and physiological responses.. The ability to detect and respond to change is a basic property of life. Theories of origin of life. What is life?. The condition that distinguishes . animals and plants. from . inorganic matter. , including the capacity for . growth. , . reproduction. , . functional activity.
